How extreme does Koh Kong's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the Khlong Yai station 20 km away. Updated through May 2026 — 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 Koh Kong has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day

109°F Oct 17, 1987

That is about 20°F hotter than a normal October afternoon in Koh Kong (typical high near 89°F).

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.

Koh Kong's record heat sits well above even a hot day for the season — October's 109°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

In a normal year, Koh Kong's warmest days reach the low 90s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 109°F and as low as 58°F. A single day has delivered over 20 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 & precipitation — 1991–2020 normals computed from 26 years of daily observations at Khlong Yai, a weather station, about 20 km from the city centre. The underlying daily records come from NOAA's global station network.
