The National Command Center for Disaster Prevention and Mitigation has issued a heat advisory as temperatures in Thailand surpass 40°C, posing significant health risks. The extreme heatwave, which is expected to persist until at least March 6, is most severe in the northern and northeastern regions. Officials warn that those participating in outdoor activities, such as golf and football, should take precautions to prevent heatstroke, which can lead to loss of consciousness or, in severe cases, be fatal.
Despite the heat warning, air quality in Bangkok and nearby provinces has shown improvement due to seasonal weather changes and stronger winds. According to the Pollution Control Department, pollution levels in the central, southern, and eastern regions have decreased. However, some areas, including Map Ta Phut in Rayong and several northeastern provinces, still report high levels of PM2.5 pollution. Ubon Ratchathani recorded the highest pollution level in the country at 87.8 micrograms per cubic meter (µg/m³), followed by Yasothon and Mukdahan.
Satellite data from the Geo-Informatics and Space Technology Development Agency (GISTDA) detected 760 heat hotspots across Thailand, with Tak, Lampang, Chaiyaphum, and Kalasin among the most affected provinces. Meanwhile, neighboring Myanmar recorded 3,159 heat hotspots, raising concerns over cross-border pollution impacting Thailand’s air quality. However, upcoming rainfall in Cambodia on March 6 and 7 is expected to help reduce PM2.5 levels in northeastern Thailand.
The Thai Meteorological Department officially declared the start of summer on March 3, forecasting high temperatures nationwide. Authorities caution that shifting wind patterns over the next two days may temporarily worsen air quality in northern provinces. Residents and outdoor workers are urged to take preventive measures, including staying hydrated, wearing light clothing, and avoiding prolonged sun exposure during peak hours.
Government officials, meteorologists, and environmental agencies continue to monitor the situation, emphasizing the importance of public awareness and precautionary measures in coping with both the extreme heat and fluctuating air quality.
