India’s extreme rain
Every reading against its published limit. Every gap named.
Year round
PERIODIC — an archive, not a live gauge
13days
over IMD’s heavy-rain threshold in 2025 · Mangaluru, Karnataka
4,283 mm in the year, +69% on its normal
IMD calls 64.5 mm in 24 hours heavy rain. Crossed 13 times in one year — and no rule caps how often.
12 grid points, ECMWF ERA5 / ERA5-Land reanalysis. What counts as extreme.
A year’s rain in an afternoon
Across these 12 cities there is more rain, and more days heavy enough to cross IMD’s threshold. What this data does not show is rain getting more concentrated.
A flood is not a weather event. It is rainfall meeting a decision about where to build.
Annual rainfall rose at 9 of these 12 cities, and extreme-rain days at 8. 6 of 12 are already above their own normal this season.
The heaviest 24 hours in the whole archive is 336 mm at Patna on 30 June 1996 — 1.6× IMD’s top class, and thirty years ago. The record is not the story here; the frequency is. 2025’s heaviest day anywhere on this list was 159 mm at Guwahati.
Who it kills
3,594 people in 2024, from five named causes in one official table. Four of the five rose.
3,594
deaths from flood, landslide, lightning, torrential rain and cyclone, 2024
361 + 39 + 2825 + 351 + 18 for 2024; 266 + 61 + 2560 + 239 + 2 for 2023. Addition on five published rows of one table, nothing else.
2,825
of them from lightning alone
More than the other four causes put together (769). Lightning is the largest single killer in India’s whole table of deaths from forces of nature, and it is almost never the subject of a climate story.
Counted or measuredModelled
The five causes, 2024
Landslide deaths rose 46.9% and flood deaths 35.7% in one year. Cyclone deaths went from 2 to 18 — a small number moving a long way, which is what a single landfall looks like in an annual table.
These are recorded deaths, and they are a floor. A death enters this table only if an authority attributed it to a named cause and filed it. And 1,626 deaths in the same table — 20.6% — have no named cause at all.
There is no national count of landslide EVENTS, flash floods or cloudbursts. NCRB counts deaths by cause; nobody publishes how many times the ground moved. A landslide’s death toll is counted. The landslide is not.
What counts as extreme
IMD classifies a rainfall day, and the boundaries are its own. So an extreme rainfall day is a countable event, not an adjective.
Every “extreme rain day” on this page is a day that crossed 64.5 mm at that grid point. Nothing here is a judgement about whether the rain was unusual — it is a comparison against a notified boundary.
IMD classifies a DAY, not a storm. 200 mm in three hours and 200 mm spread over a full day are the same category and are not the same event. That distinction is why a day-class cannot tell you whether a street flooded.
Not just the monsoon
Extreme-rain days are counted over the WHOLE YEAR, not just the monsoon. Chennai's extreme rain is the northeast monsoon in October and November, and a June-September window would miss it entirely. The monsoon total is reported separately per station.
The monsoon total is still reported for every city, and the season-to-date figure is compared with the same calendar dates in the 1991-2020 normal — never with a whole-season normal, which always makes a season look dry.
Three things, named rather than estimated
- CLOUDBURSTS ARE NOT COUNTED. IMD defines one as 100 mm or more in a single hour. ERA5 is a ~9 km reanalysis that smooths convection, so a real cloudburst appears in it as an ordinary wet hour — counting them here would return roughly zero everywhere, and that zero would be a fact about the instrument, not about India. There is also no public national cloudburst register to check against.
- FLASH FLOODS ARE NOT COUNTED for the same reason: there is no public national register of flash flood events, and rainfall alone does not determine whether one happens — terrain, land use and drainage do.
- LANDSLIDE COUNTS are not published nationally either. NCRB publishes landslide DEATHS, which is a different quantity and is used instead, from its own table.
- India's official rainfall departures are IMD's, computed on its own gauge network by subdivision. These are computed here from a reanalysis and are not IMD's figures.
A zero from the wrong instrument is not a zero. A 9 km reanalysis asked how many 100 mm hours India had would answer “almost none”, and that answer would be about the model, not the country.

Twelve cities
Days over IMD's heavy-rain threshold in 2025, and the year's total beside it. Season-to-date figures beside each city run to 13 September 2026.
A sum of station-days, NOT a national count of extreme rainfall days. 32 station-days across 12 cities in 2025.
Every city against its own normal
All figures in millimetres unless marked. “Top 5 days” is the share of the year’s rain that fell on its five wettest days — one division on two measured numbers, and the closest this page gets to describing how concentrated the rain is.
What is changing
More rain, in more extreme days. The concentration is the part that is not moving.
Four measures, the first eighteen years against the last, counted across all 12 cities. The pale bar is cities where it rose, the grey where it did not move, the dark where it fell.
Rainfall is up at 9 of 12 cities and extreme days at 8. But the share arriving in the five wettest days is down at 8 of them — so this dataset shows more rain and more extreme days without showing rain getting more concentrated.
How many of the reporting stations move each way between the first and second halves of the record. Counted as stations, never averaged into a national trend. And ERA5 reanalysis — a model constrained by observations. Rain is far more local than heat: one gauge can record a cloudburst another two kilometres away never sees, and a 9 km cell has one answer.
And who is looking
Views of the English Wikipedia article on climate change in India. Lighter bars are monsoon months. Peak 8,800 in Jan 2022, floor 1,173 in Aug 2026 — 7.5×. It measures attention, never rainfall.

Coverage follows the flood, not the rainfall. A 300 mm day in a place with drainage is a wet afternoon. The same day where a lake was built over is a disaster. The rain is the same; only one of them gets a headline — and it is the second one that tells you something about a city.
What you can do
Rainfall is weather. A flood is a decision.
Find out what was there before
Most urban flooding happens where water used to go — a lake, a nala, a floodplain. City master plans and old survey maps are public. If your street floods, something was built on the way out.
Lightning is the one you can act on today
2,825 deaths a year, mostly outdoors, mostly avoidable with thirty minutes of shelter. It is the largest killer on this page and the cheapest to reduce.
Ask who signed it off
Every building on a floodplain has an approval with a name on it. That is a public record, and it is a more useful question than how much it rained.
Every figure here is public, dated and reproducible from the source named beside it.
A gap is a gap
An empty day stays empty — a gap in the record is a gap in the record, never a zero.

Reuse freely — CC BY 4.0. Every figure carries its source and its cadence in how the number is made. If you quote a number from here, quote the kind with it. Each upstream source keeps its own terms.
This is what we are doing.
It is not enough.
The work against this reading
Mostly the written record, and going to look. Three of the essays on this site were reported out of flood years, and Gram Anubhav takes groups into villages living with this, run with over a hundred grassroots partners in the villages themselves.
And why it is not a reply
Publishing and going to see are not resilience. Swechha does not build drainage, and nothing here reduces the 3,594 deaths this page counts. What the work does is make the count harder to ignore — a smaller claim than it sounds, and the only one the evidence supports.
Understand the data
- What counts as extreme rainfall?IMD's day categories — and the reason a day is the wrong unit for a cloudburst.
- How is Delhi's rainfall measured?Gauges, a seasonal normal, and why two Delhi rainfall figures rarely agree.
- Measured or modelled?The first question to ask of any environmental number, and the one most often skipped.
