India does not have one safety season. The same week can bring a cold wave in Punjab, a cyclone alert on the Odisha coast and a landslide on a Uttarakhand road. This calendar lists what usually peaks in each month, the festivals and crowd events that tend to fall there, three lessons from our own case studies, and the guides worth reading first. It is built from IMD, NDMA, NCRB and health ministry material, and it states clearly when a figure is one year of record and not a forecast.
Open the current month first. Read the three actions, then the guides. Hazards differ by region, so use the month as a prompt and check IMD's Mausam app and your State Disaster Management Authority for your own area. Festival dates move every year; where we give a month it is a range, so check a current calendar. To get a reminder on the 1st of each month from November 2026 to October 2027, add the calendar file to your phone. The file contains only the month's short reminder and a link back to this page.
Choose a month
Festival dates move every year, so festivals are shown as a month or range, never an exact day. January, February and May rest on thinner sources and are marked; the page says so wherever it matters. How we know
January
January: Cold waves, fog and winter nights
Cold waves and dense fog hit the north; sleeping spaces, road trips and wedding travel carry the risk.
Thinner sourcing
Hazards this month
Cold-wave spells and fog over north India. IMD's 2025 report records cold-wave days in January 2025 in Himachal Pradesh, Punjab and north Rajasthan with adjoining Haryana, though over a small area and for few days. How severe a January is changes every year. S01
Cold itself kills quietly: NCRB recorded 833 deaths from exposure to cold in 2024 (a full-year count, not January alone). S11
The forest-fire season that runs from November to June has begun in dry forest areas. S16
Festivals and crowds
Lohri, Makar Sankranti, Pongal and Magh Bihu (mid-January, usually the same dates each year)
Republic Day events and parades (26 January, central holiday)
Wedding season in many states (usually runs through the winter months; check local muhurat dates)
Mid-January festivals fall on or near the same dates each year. Wedding dates differ by region and panchang, so check your own calendar.
Do this month
1
Walk your family through the exit from every bedroom at night, and keep the keys where everyone can reach them.
2
Drive slower in fog and leave early; if you cannot see far, stop somewhere safe and wait.
3
Before a wedding or function trip, count seats against passengers and ask for the driver's rest plan.
Sourcing for January: medium. Cold-wave and fog facts come from the IMD 2025 annual report, which is one year of record, not a forecast. No official source was found for fire risk specific to winter, so none is claimed.
February
February: Late winter, exams and market fires
Winter loosens its grip but western disturbances can bring hail and heavy hill rain; exam season and crowded markets need fire care.
Thinner sourcing
Hazards this month
Western-disturbance weather in late winter. In IMD's 2025 report, heavy rain, floods and landslides on 27 and 28 February 2025 caused 9 deaths in Jammu and Kashmir and Himachal Pradesh, and hailstorms damaged crops. S01
Cold-wave spells can still return early in the month, as they can in January (see January). S01
Forest-fire season (November to June) is under way; the peak comes later, from April. S16S15
Festivals and crowds
Maha Shivratri (usually February or March)
Ramzan fasting month, in 2027 expected to end with Eid-ul-Fitr in March
School and board examinations (many boards start in February or March)
Check the calendar for Shivratri and Ramzan. The CBSE 2027 date sheet was not out when we checked.
Do this month
1
Charge e-scooters and power banks in the open, awake and away from exits and stock.
2
Print the home fire checklist and walk through the house with a pen.
3
If you run a shop, keep the lane to your shutter clear and keep one extinguisher where staff can see it.
Lessons from our case studies
Seelampur Market Fire: Charging-Scooter Claim, Cause Still UnconfirmedSeelampur, 22 February 2026: a major fire in a congested cloth market; some accounts blamed a charging scooter but the official cause was not established. Crowded markets need clear lanes, alarms and a rule on where batteries are charged.
Sourcing for February: medium. Hazard text relies on one year of IMD record. No official source gives exam dates for 2027 yet. The Seelampur lesson carries the case's own caveat that the cause is unconfirmed.
March
March: Heat starts, Holi and thunderstorms
IMD's pre-monsoon season begins; heat waves can start by mid-March, and Holi and Eid crowds gather.
Hazards this month
Heat waves typically occur from March to June, and rarely into July. In March 2025 IMD recorded heat-wave conditions over western India on 10 to 15 March and over east-central India on 15 to 18 March. S04S01
Pre-monsoon (March to May) thunderstorms and lightning: in the 2025 pre-monsoon season IMD's report, based on media reports, counts 289 lightning deaths and 179 deaths from thunderstorms. S01
Forest-fire season (November to June) continues and builds towards the April to June peak. S16S15
Festivals and crowds
Holi (usually falls in March; in 2027 the central holiday list places it in March)
Eid-ul-Fitr (in 2027 expected in March)
Good Friday (March or April)
Board examinations and school annual days
Check the calendar for exact dates; they move every year.
Do this month
1
Start the heat routine early: water bottle, cap or umbrella, and no hard outdoor work in the hottest hours.
2
Have the AC, wiring and fans checked before the first heat wave, not during it.
3
On a night bus, check where the emergency exit is before the bus moves.
Sourcing for March: strong. March heat and the season window are in NDMA and the IMD 2025 report. Festival months for 2027 are from the DoPT list as reproduced by StaffNews.
April
April: Heat waves, forest fires and lightning
Heat waves build in the north-west and centre; forest fires and pre-monsoon lightning rise.
Hazards this month
Heat waves. IMD's April 2025 record shows Rajasthan and Gujarat with 6 to 11 heat-wave days, and East Madhya Pradesh and Vidarbha with 4 to 6. S01S04
Forest fires are mostly experienced in the summer months from April to June, varying by state and forest type. S15
Pre-monsoon thunderstorms and lightning continue (2025 pre-monsoon season: 289 lightning deaths and 179 thunderstorm deaths, per IMD's media-based count). S01
Heat stroke deaths: NCRB recorded 1,832 deaths from heat and sun stroke in 2024, up from 804 in 2023 (full-year counts). S11
Festivals and crowds
Ram Navami (usually April; in 2027 the central list places it in April)
Mahavir Jayanti, Baisakhi, Vishu, Tamil New Year and Bihu (mid-April)
Wedding season and summer holidays begin in many states
Ram Navami processions draw crowds in heat. Check the calendar for exact dates.
Do this month
1
Drink water before you are thirsty and carry ORS if you work or travel outdoors.
2
Never light a fire, burn waste or throw a cigarette near dry grass, forest or hill slopes.
3
When thunder starts, go into a pucca building or a closed hard-top vehicle; do not stand under a lone tree.
Lessons from our case studies
Kolkata Rituraj Hotel Fire, April 2025: 14 Deaths and the LessonsKolkata, 29 April 2025: a fire on the first floor of the Rituraj Hotel killed 14; most died from smoke. Guests in a hotel should find the nearest staircase on arrival and never use the lift in a fire.
Sourcing for April: strong. IMD, NDMA, PIB and NCRB all cover this month. Counts of 2025 deaths in the IMD report are based on media reports, as the report states.
May
May: Peak heat, AC fires and early cyclones
The hottest weeks of the year, heavy AC load, storms, and the second cyclone peak on the coasts.
Thinner sourcing
Hazards this month
Heat waves peak. IMD's May 2025 record shows Rajasthan, Jammu and Kashmir and Ladakh with 6 to 11 heat-wave days; heat waves can run into June and, rarely, July. S01S04
Cyclones: the north Indian Ocean has a main peak in November and a second peak in May, and May-June produces cyclones of severe intensity. Amphan (May 2020), Tauktae (May 2021) and Yaas (May 2021) are among the May storms in IMD RSMC reports. S03S24
Forest fires: April to June is the usual season. Pre-monsoon storms bring lightning and gales. S15S01
Fire calls rise in severe heat. Delhi Fire Service figures reported in May 2024 showed more than 220 fire calls a day. Experts quoted in the press linked this to AC and transformer load, but no official statistic proves the link. S25
Festivals and crowds
Eid-ul-Zuha (Bakrid) (in 2027 expected in May)
Buddha Purnima (May)
Summer vacations and hill-station travel; school and college results; wedding season
Dates of Eid move with the moon. Check the calendar.
Do this month
1
Look at AC plugs, sockets and extension boards: any that feel hot or smell of burning should be changed.
2
Check every time before locking a car: no child, no pet.
3
If you live on a coast, save the cyclone warning sources (IMD Mausam app, SACHET alerts) and pack your emergency bag.
Lessons from our case studies
Gulzar Houz Fire Tragedy, Hyderabad – May 2025Hyderabad, 18 May 2025: 17 members of one family, including eight children, died of smoke and burns in a dense building with a shop below the homes. The cause was not finally established; a preliminary forensic view pointed to AC compressors.
Budaun Village Fire During Storm, May 2025Budaun, 21 May 2025: during a storm, a reported transformer spark spread through about 200 houses in a village; nobody died. Storm-season checks on power equipment and firebreaks between houses matter.
Sourcing for May: medium. Season facts are strong (IMD, RSMC, NDMA, PIB). The heat-to-fire link is only a media-reported expert view and is stated that way; no official causal statistic was found.
June
June: Monsoon arrives, cyclones and snakes
The monsoon normally reaches Kerala around 1 June; storms, lightning, snakebite and the last cyclones of the pre-monsoon season.
Hazards this month
The southwest monsoon normally sets in over Kerala around 1 June and covers the whole country around 15 July. The IMD monsoon season is June to September. S17S02
Cyclones: May-June and October-November are known to produce cyclones of severe intensity; Vayu (June 2019), Nisarga (June 2020) and Biparjoy (June 2023) are in IMD RSMC reports. S03S24
Lightning with thunderstorms: in the 2025 monsoon season IMD's report counts 669 lightning deaths, based on media reports. S01S08
Snakebite risk rises in the rainy season. The national snakebite action plan says the risk is greater in the monsoon, which coincides with heavy farm work and the snake breeding season. S12
Heat waves can still occur in June, especially in the north. S04
Festivals and crowds
Rath Yatra (usually falls in June or July)
Muharram (in 2027 the central list places it in June)
Monsoon treks and pilgrimages begin
Rath Yatra gathers very large crowds in Puri; check the calendar for exact dates.
Do this month
1
Carry a torch at night and wear closed shoes when walking outside in the dark.
2
Find the nearest hospital with anti-snake venom and keep its number with the emergency numbers.
3
Clear drains and gutters near your home before the heavy rain begins.
Sourcing for June: strong. IMD pages and the NAP-SE document back the onset, cyclone and snakebite statements. Rath Yatra month is general knowledge and is not sourced from an official list.
July
July: Floods, landslides and waterborne illness
The monsoon is at full strength: floods, waterlogging, lightning, landslides on hill roads, snakebite and waterborne illness.
Hazards this month
Heavy rain, floods, cloudbursts and landslides. IMD's 2025 report counts 1,082 deaths from these in the June to September monsoon season, based on media reports. In 2025 the full monsoon season totalled 1,785 reported deaths. S01
Lightning remains a major killer in the monsoon (669 reported deaths in 2025). S01S08
Snakebite risk is higher in the rainy season, particularly after floods. S12
Illness from dirty water and mosquitoes. Dengue cases upsurge from July to November and peak after the monsoon. S13S10
Landslides on hill roads after heavy rain; NRSC's Landslide Atlas (2023) maps about 80,000 landslides in 17 states and two union territories (figure via our landslide guide). S07S26
Festivals and crowds
Kanwar Yatra and the month of Sawan (usually July and August)
Guru Purnima and Rath Yatra (June or July)
Amarnath Yatra and other hill pilgrimages (usually in the monsoon months)
Nashik-Trimbakeshwar Simhastha: first bathing days fall in August and September 2027 as reported
Kumbh and Mela periods are set by their organisers; check official notices. The Nashik schedule is from a press report.
Do this month
1
Never enter floodwater on foot or in a vehicle; turn around and take another route.
2
Avoid hill roads during continuous heavy rain, and check that the road is open before you leave.
3
Empty standing water from coolers, buckets and pots weekly to cut mosquito breeding.
Sourcing for July: strong. IMD report totals are media-based counts and are labelled so. The landslide atlas figure comes via our own post and was not re-opened at NRSC.
August
August: Hill landslides, festival crowds and Sawan
Heavy rain continues on the Himalayan and Western Ghats slopes while Sawan, Janmashtami and Ganesh festival crowds build.
Hazards this month
Heavy rain, floods, cloudbursts and landslides continue to be the leading monsoon killers (1,082 reported deaths in 2025, June to September). S01
The monsoon is the main season for these events: IMD's 2025 report counts 1,082 reported deaths from heavy rain, floods, cloudbursts and landslides in the monsoon against 122 in the whole pre-monsoon season. Wayanad's landslides on 30 July 2024 killed more than 200 people in a night, according to our landslide guide. S01S26
Crowd crushes and structure failures at religious gatherings are a recurring festival-season risk (NCRB counted 147 stampede deaths in 2024, up from 32 in 2023). S11S21
Sourcing for August: strong. The IMD report and NCRB figure support the hazard text. Festival months for 2027 are from the DoPT list as reproduced by StaffNews; Ganesh Chaturthi date was not on that list.
September
September: Late floods, immersion and drowning
The monsoon starts to withdraw but rivers stay high; Ganesh immersion puts crowds beside water.
Hazards this month
Monsoon withdrawal from the extreme north-west is not attempted before 1 September, so heavy rain and river floods can continue through the month. The IMD season ends on 30 September. S18S02
Drowning is a leading accident cause: NCRB recorded 40,044 drowning deaths in 2024 (full-year count). S11
Dengue and waterborne illness stay high after the rains (July to November upsurge). S13S10
Floods in 2026 included Uttar Pradesh and Bihar river floods and a flash flood at Nilambur in Kerala on 20 September (our case studies). S27
Festivals and crowds
Ganesh Chaturthi and immersion (usually August or September)
Onam (usually late August or September)
Pitru Paksha (September or October)
Navratri may begin by the end of the month, depending on the year
Immersion days fall on several dates across ten days or more. Check your local committee's schedule.
Do this month
1
Keep children and elders on the shore during immersion; send one trained, supervised group at a time.
2
Never enter water to rescue someone without help; throw a rope or a floating object instead.
3
Do not visit a hill stream or waterfall during or just after rain; it can rise even when it is dry where you stand.
Sourcing for September: strong. Withdrawal and season end are from IMD; the NCRB drowning count is full-year. The 2026 flood events are from our own case studies, not an official summary.
This month
October: Puja crowds, crackers and the first cyclones
Navratri, Durga Puja, Dussehra and Diwali preparations; stubble burning begins; the post-monsoon cyclone season opens.
Hazards this month
The southwest monsoon withdraws from the entire country around 15 October (IMD recorded 16 October in 2025), and the northeast monsoon begins over Tamil Nadu and nearby coasts. S02S01
The post-monsoon cyclone season opens (October to December). In 2025 IMD recorded Severe Cyclonic Storm Shakhti (1 to 7 October) and Montha (25 to 29 October). November has the main yearly peak. S01S03
Paddy stubble burning in Punjab and Haryana. For 2026, CAQM deployed flying squads in 34 districts (18 in Punjab and 16 in Haryana) from 1 October to 30 November. S14
Festival crowds and temporary structures: pandal gates, barricades, electric wiring and rain. See the NDMA crowd list in our pandal guide. S21
Fireworks injuries: NCRB recorded 110 accidental fires caused by fireworks in 2024, with 112 people injured and 134 deaths over the year. S22
Festivals and crowds
Navratri, Durga Puja and Dussehra (usually fall in late September and October; in 2027 the central list places Dussehra in October)
Diwali (falls in October or November; in 2027 the central list places it in October, and in 2026 in November)
Karva Chauth, Dhanteras and Diwali shopping crowds (October or November)
Nashik-Trimbakeshwar Simhastha: opening flag-hoisting reported for 31 October 2026
Check the calendar for exact dates. Many cities set local cracker rules, so check your own city order.
Do this month
1
At any pandal or mela, note two exits before you go in and leave if the crowd starts to push.
2
Keep diyas on a steady, non-burning base and away from curtains; no open flame while a gas cylinder is being changed.
3
Keep two buckets of water and one of sand near where crackers are lit, and keep children at a distance.
Sourcing for October: strong. Stubble-burning dates are from a Ministry statement carried by All India Radio. The fireworks numbers come via our own Diwali guide citing NCRB. Festival dates for 2026 and 2027 are given by month only.
November
November: Cyclone peak, smog and Diwali
The yearly cyclone peak, smog in the north, early cold waves, Diwali and Chhath crowds.
Hazards this month
November is the main peak month for tropical cyclones in the north Indian Ocean (primary peak in November, second in May). In 2025 IMD tracked Cyclonic Storm Senyar (25 to 27 November) and Cyclone Ditwah (27 November to 3 December). S03S01
Smog and stubble-burning smoke in the north: CAQM's flying squads in Punjab and Haryana run until 30 November in 2026. S14
Early cold waves. IMD recorded cold to severe cold-wave conditions in isolated pockets over north-east Rajasthan, south Haryana, north Madhya Pradesh, south Uttar Pradesh and north Chhattisgarh from 8 to 18 November 2025. S01
Dengue cases are still high (July to November upsurge). S13
Diwali firecrackers: NCRB recorded 110 accidental fires from fireworks in 2024 (full-year count). S22
Festivals and crowds
Diwali (usually falls in October or November; in 2026 it is in November)
Bhai Dooj, Govardhan Puja, Chhath Puja (usually a few days after Diwali)
Guru Nanak Jayanti (November)
Wedding season picks up in many states
Chhath ghats put crowds beside water and need immersion-style care. Check the calendar for dates.
Do this month
1
Use only one appliance per socket and throw away light strings with cracked insulation.
2
If you live on the east coast, check your cyclone warning sources and keep your emergency bag packed.
3
On bad-air days, keep windows shut during the worst hours and limit outdoor exercise.
Sourcing for November: strong. Cyclone peak is from the RSMC FAQ; 2025 storm names are from the IMD annual report. Diwali month for 2026 comes from our own guide citing the central holiday list. Smog health advice is general and was not sourced to NDMA, whose smog page was empty when opened.
December
December: Cold waves, dense fog and year-end crowds
The coldest, foggiest weeks in the north; late cyclones in the south-east; Christmas, New Year and school-function crowds.
Hazards this month
Cold waves. IMD recorded cold-wave conditions for 8 to 15 days over parts of Chhattisgarh, West Madhya Pradesh and Punjab in December 2025, and for 1 to 7 days across many other states. S01
Dense fog: 15 to 26 days of dense to very dense fog over the Indo-Gangetic Plain (Punjab, Haryana, Uttar Pradesh) and parts of Himachal Pradesh and Uttarakhand in December 2025, and 26 days over Odisha. S01
Cold exposure killed 833 people in 2024 according to NCRB (full-year count). S11S05
The post-monsoon cyclone season (October to December) runs on, with Mandous (December 2022) in IMD RSMC reports, and northeast-monsoon rain over Tamil Nadu and nearby coasts. S03S24
Festivals and crowds
Christmas and New Year gatherings (25 and 31 December)
School annual days and winter-break trips
Wedding season continues
Pilgrimage and tourist travel to hills and beaches over the winter break
Year-end parties and school functions need exit checks.
Do this month
1
Stay below the speed at which you can stop in the distance you can see; if fog is thick, pull off the road safely and wait.
2
Never run a generator or a charcoal sigri in a closed room; carbon monoxide has no smell.
3
At any party, school function or restaurant, look for the exits before you sit down.
Jaipur-Ajmer Highway LPG Tanker Fire IncidentJaipur-Ajmer highway, 20 December 2024: a container truck hit a turning LPG tanker and escaping gas exploded, burning about 40 vehicles; PESO's record lists 20 deaths.
Sourcing for December: strong. The December 2025 IMD record gives cold-wave and fog days. The Dabwali and Kamala Mills lessons are historic cases, kept for the crowd-exit point. Charcoal-sigri carbon monoxide advice is general and not tied to a source in this pack.
Add reminders to my calendar
One all-day reminder on the 1st of each month for the next 12 months, with a short safety line and a link back to this page. The file is made in your browser. We receive nothing, and it holds no personal data.
Needs JavaScript. It downloads a .ics file that Google Calendar, Apple Calendar and Outlook can open.
How we know
Each hazard line is tied to the sources below by its code (S01 and so on). Hazard statements are anchored to the sources listed at the end. Counts drawn from IMD's annual report are for 2025 and are based on media reports, as the report says. They show what has happened, not what will happen. Last checked 19 October 2026.
Where the evidence is thin
January, February and May are marked "thinner sourcing". January and February rest on one year of IMD records (2025), not a long-term average, and we found no official source for winter-specific fire risk, so none is claimed. For May, the link between heat and building fires is only a press-reported expert view, and it is worded that way.
Death and event counts taken from the IMD annual report are for 2025 and are the report's own media-based counts. They show what was recorded in one year, not an average or a forecast.
We did not open monthly climate normals (how often cold waves or fog occur in each month). Month placement rests on the IMD 2025 report and NDMA pages. For normals, use IMD's climate pages.
Rath Yatra, Ganesh Chaturthi, Maha Shivratri, the start of Navratri and Durga Puja, Chhath, Sankranti, Pongal, Lohri and the wedding season have no official source here. They are stated only as a month or range with "usually", and the wedding season is unsourced.
The Nashik-Trimbakeshwar Simhastha dates come from a press report, and a second site gave conflicting dates. The page calls them "reported". The CBSE 2027 date sheet had not been published when we checked, so exam months are not dated.
Charcoal and generator carbon monoxide advice and the smog advice are general safety advice from our guides, not tied to an official source.
This calendar shows what usually happens in each month. It is not a forecast. For warnings, use the IMD Mausam app, your State Disaster Management Authority and NDMA SACHET alerts.
Common questions
Are the festival dates exact?
No. Festivals follow the lunar calendar and move every year, so we give the month or a range, such as 'usually falls in October or November'. Check a current calendar or your city's notice for the exact day.
Is this a weather forecast?
No. It shows what usually happens in each month, using IMD and NDMA material and one recent year of IMD records. For a forecast, use the IMD Mausam app, the IMD website and the SACHET alerts from NDMA.
Why does my area not match the month shown?
India is large. The north has cold waves and fog in December while the south-east coast is in cyclone and northeast-monsoon season. Use the month as a prompt and check your own state's disaster authority and IMD district warnings.
What does the calendar file add to my phone, and does it hold personal data?
It adds one all-day reminder on the 1st of each month from November 2026 to October 2027. Each carries a short safety line and a link to this page. It holds no name, email, location or other personal data.
Who do I call in an emergency?
Dial 112 for any emergency, 101 for fire and 108 for an ambulance. Our guide to emergency numbers explains which to use, and a state-wise list covers local helplines.
