Thailand could experience extreme heat this April, experts predict; with temperatures expected to reach 44 degrees Celsius in some areas. According to the World Meteorological Organization (WMO) and the Thai Meteorological Department, April 2025 will be the hottest month of the year. Daytime temperatures in Bangkok may average 35 degrees Celsius, while provinces in the north such as Mae Hong Son, Tak, Chiang Mai, Lampang, Uttaradit, Loei and Sukhothai could reach 42-44 degrees Celsius.
According to a National News Bureau of Thailand post, the increase in temperature is linked to low-pressure systems, combined with moist air currents from the Gulf of Thailand, which causes higher humidity and heat. The same report suggests that 2025 could be Thailand’s third-hottest year in seventy years, following record-breaking temperatures in 2024 and 2023. Lampang recorded 44.6 degrees Celsius in April of 2024.
Global warming contributes to long-term climate change. Rising greenhouse gas emissions have already pushed a 1.5 degree celsius increase, higher than pre-industrial levels.
Health officials warn the public of heat related illnesses such as heatstroke, which may occur in temperatures above 40 degrees celsius. Symptoms include severe fatigue, dizziness, muscle cramps, seizures, or in extreme cases, organ failure.
The public is also advised to wear breathable clothings, consume sufficient water, and limit outdoor exposures.
