About 0.1°F per decade, measured from Ang Thong's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Ang Thong's climate has warmed more slowly than most other cities in Thailand.

not a straight climb.
When in the year the change shows up
How much warmer each month is now than in the 1970s.
Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
November has warmed the most — about 1.9°F. The warming runs across the whole year, not just one season.
