Thailand Set to Enter Summer Season with Potential Temperatures Reaching 43°C

BANGKOK — The Thai Meteorological Department announced on 19 February that Thailand will officially enter the summer season on 22 February 2026, with temperatures expected to reach as high as 42–43°C this year. The department warned of unstable weather conditions during the seasonal transition period from 23–25 February, with summer storms forecast for upper Thailand. Thunderstorms, strong winds, and possible hail are anticipated as cold and hot air masses collide. Temperatures may temporarily drop after the storms before rising again. This year's summer is expected to be hotter than last year, particularly from mid-March to April, with provinces like Mae Hong Son, Lampang, and Tak potentially experiencing temperatures exceeding 42°C. The summer season is likely to end around mid-May. Globally, Thailand's weather will be influenced by a weakening La Niña pattern transitioning to neutral conditions, with near-average rainfall expected. The department's director-general advised the public to take precautions during extreme heat, avoid outdoor activities between 10:00 and 19:00, and remain vigilant about fire hazards. People can follow official warnings and forecasts via the department's website or by calling the 24-hour hotline 1182.
