A Year in Three Parts, Not Two
Most tropical cities are sold to visitors as wet and dry. Bangkok runs on three seasons, and the difference matters, because the same itinerary that is a pleasure in January is close to unworkable in April. Cool, hot and monsoon each behave differently enough to change what a day here costs you in effort.
The Cool Season (November to February)
Highs of 31 to 33°C, lows near 24, and one to four wet days a month. The humidity that defines the rest of the year briefly lifts, and this is the only stretch when walking between temples in the middle of the day is comfortable rather than a decision. It carries the fullest festival calendar too. December and February run very busy and price accordingly; November is the same weather for less.
The Hot Season Is the One to Plan Around
April is the hottest month of the Bangkok year at 28 to 40°C, and it is also one of the busiest, because Songkran falls in the middle of it. That combination catches people out: they book around the festival and meet the heat. If you are coming for Songkran, come for Songkran and accept the rest of the fortnight. If you are not, March and May are the same city without either.
The Monsoon Is Not the Season People Fear
Thirteen to eighteen wet days a month sounds decisive and is not. The rain arrives late in the afternoon, falls hard, and stops, and the temperature sits three or four degrees below the hot season. What it buys is emptiness: May through October is six consecutive months rated low for crowds, the longest quiet run of any destination on this site. Nothing closes, and the rooftops are still there between showers.
Our Bangkok Guides
Fifteen guides, three seasonal overviews and all twelve months. They are written to answer the question the seasons raise rather than restate it: which weeks inside a season are worth paying a premium for, and which are the same trip for considerably less.
