Best time to visit Surat Thani

February is the best month in Surat Thani, scoring 73 out of 100, with May the weakest at 41. The 32-point spread means timing is worth planning around without being decisive. Only that one month come close to the top, which makes the timing narrow.

April is the warmest month at 32.8 °C and December the coolest at 28.9 °C — a 3.9 °C spread across the year. 184 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season.

There is a real wet season here. May, July, September and October carry the rain — up to 28 wet days in a month — while January to March drop as low as 5. That 23-day gap is the biggest single difference between a good month and a bad one in Surat Thani, and it moves further than the temperature does.

Daylight barely moves: about 12.7 hours whatever the month, which removes one variable from the decision entirely.

The three strongest months are February, January, March. The one to think twice about is May. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
