A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

Getting there

How far Bangkok is, and what it costs, depends on where you set off from — the months above do not.

The year in Bangkok

Bangkok has a tropical climate with a distinct wet season from May to September. The climate data indicates potential for extreme heat in the shoulder period.

Busiest	mid Nov to late Feb — Cooler weather and lower humidity attract many tourists.
Quieter, still good	early Mar to late May — Transitioning from cool to hot weather, prices may be lower. early Oct to late Oct — Tapering rainfall before peak season begins, decent value.
Wet or stormy	early May to late Sep — monsoon, moderate
Watch out for	extreme heat; haze

This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
