How extreme does Galle's weather get?

The hottest, coldest, wettest and snowiest days Galle has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 23 years of daily weather observations (2002–present), from the Galle station 2 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Galle has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Galle has reached as high as 103°F and as low as 64°F. A single day has delivered over 11 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.

Methodology & sources

Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 12 years of daily observations at Colombo, a weather station, about 102 km from the city centre. The underlying daily records come from NOAA's global station network.
