May starts the wet and rainy season in Bangkok, and the heat tapers down slightly. The average temperatures are in the 26.1°C (79°F) to 34.4°C (93.9°F) range as the humidity increases to about 75%.
The rainfall is to the tune of 248.9mm (9.8") and at least half the days in May witness cloud cover. The equatorial nearness produces convectional rain nearly every day and reduces the stifling heat. Heavy showers are likely, as are lightning and thunderstorms - it is almost mandatory to carry umbrellas or wear rain jackets while exploring Bangkok during the outbreak of the monsoon.
