Bangkok answers
When is the best time of year to be in Bangkok?
Quick answer
The cool season around November to February is the most comfortable. The rainy season runs roughly May to October, and the hottest months fall in between.
Bangkok has three broad seasons: cool and dry from around November to February, hot from March to May, and wet from roughly May through October. The cool season is the most comfortable for walking the city and the busiest for visitors.
Rain in the wet season tends to arrive in heavy bursts rather than all day, so it is workable if you plan around the afternoon. Air quality is typically worst in the dry months, which is worth knowing if you are sensitive to it.
