Weather extremes

How extreme does Surat Thani's weather get?

The hottest, coldest, wettest and snowiest days Surat Thani 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 Surat Thani station 20 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 Surat Thani has recorded — each shown against what a normal day that time of year looks like.

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.

Surat Thani's record heat sits well above even a hot day for the season — May's 107°F is about 13°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, Surat Thani's warmest days reach the mid-90s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 107°F and as low as 58°F. A single day has delivered over 14 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
