Summer begins in Thailand at end of February, with hottest spell in March

The heat is expected to be at its most intense in mid-March. The southeasterly winds and accompanying low barometric pressure would bring thunderstorms to some parts of the country, the department said.

Additionally, the department warned of forest fires due to the hotter and drier weather being more conducive to outbreaks. Vulnerable groups should guard against heat stroke during the most intense period of summer heat, it cautioned.
