Best time to visit Thailand

Timing is simple in Thailand: almost every destination here peaks in December or February, so one set of dates works for the whole country.

Averaged across every destination listed, Thailand is at its best in December, scoring 75 out of 100, with January close behind at 74. May is the weakest month nationally at 39. The window is narrow: only 3 months come within eight points of the best, so an itinerary covering several of these places should be built around that rather than around any one city's own peak.

Thailand is climatically consistent — only 4 °C separates its warmest destination from its coolest across the year. Rainfall is broadly similar throughout, from 154 wet days a year in Ubon Ratchathani to 255 in Hat Yai.
