Has the climate in Trang changed?

Trang has warmed about 2.1°F between 1971 and 2024.

About 0.4°F per decade, measured from Trang's official daily weather records, 1971–2024. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.

Is that a lot? Trang's warming is broadly in line with other cities in Thailand — neither unusually fast nor unusually slow.

What has actually changed

Each bar is one year. Most recent years sit above the older ones. Some recent years still came in cool — warming is a slope, not a straight climb.

In day-to-day terms, that long-term shift shows up as about 19 more days above 90°F compared with the 1970s.

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.
