Bangkok in April

The hottest month of the year. Songkran, the Thai New Year, runs from the 13th to the 15th, and water fights break out on the streets. Keep your phone and wallet in a waterproof pouch.

Bangkok in April ran hot: 36°C by day and 27°C at night. By midday the shade was the best seat in town. 6 rain days in a typical April: noticeable, but most days stayed dry. April could skip rain entirely: 1 of 20 years had none, while 2021 had 15 rain days.

Highs topped 30°C on 30 days of the month on average. Mixing in indoor stops at midday made sense. Rain days averaged 19 mm each, so when it rained it rained properly.
