Weather extremes
How extreme does Trincomalee's weather get?
The hottest, coldest, wettest and snowiest days Trincomalee has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Trincomalee has recorded — each shown against what a normal day that time of year looks like.
That is about 20°F hotter than a normal June afternoon in Trincomalee (typical high near 96°F).
The three most extreme on record
About 30°F colder than a normal May night in Trincomalee (typical low near 84°F).
The three most extreme on record
About 75% of a typical December's rain in a single day (Trincomalee averages roughly 15.7 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Trincomalee's record heat sits well above even a hot day for the season — June's 116°F is about 20°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
In plain terms
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 11 years of daily observations at China Bay, a weather station, about 7 km from the city centre. The underlying daily records come from NOAA's global station network.
