A severe heatwave has set new temperature records across Southeast Asia this week, with thermometers reaching unprecedented levels in multiple countries. Thailand reported 44.6°C (112.3°F) in Tak province on Tuesday—the highest temperature ever recorded in the country.
"This is not normal April weather," said Somchai Baovornwet, director of Thailand's Meteorological Department. "We're seeing temperatures 4-5 degrees Celsius above seasonal averages, and the heat is persistent."
Other affected areas include Vietnam (43.4°C in Hue), Cambodia (42.7°C in Preah Vihear), Laos (42.9°C in Savannakhet), and Myanmar (43.1°C in Mandalay). The heat has prompted school closures, adjusted work hours, and increased hospital admissions for heat-related illnesses.
Climate scientists link the extreme heat to both global warming and regional weather patterns. "What used to be once-in-a-century heatwaves are becoming once-in-a-decade events," said climate researcher Dr. Li Wei from the University of Hong Kong.
Governments have activated heat emergency plans, including opening cooling centers, distributing water, and advising vulnerable populations to stay indoors. The heatwave is expected to continue through the weekend before some relief arrives early next week.
