Thailand Health Ministry Warns of Rising PM2.5 Levels Starting November
The Thai Ministry of Public Health has issued a warning regarding increasing PM2.5 dust levels in Bangkok, its vicinity, and the central region as the winter season begins.
On November 13, 2026, Thailand's Minister of Public Health, Phatthana Phromphat, announced that PM2.5 air pollution levels are expected to rise across Bangkok, its surrounding provinces, and the central region starting in November. According to the Ministry, the combination of winter weather patterns, specifically low atmospheric pressure and poor ventilation, creates conditions that favor the accumulation of fine dust particles.
In response to this forecast, the Ministry of Public Health has instructed local health agencies to closely monitor the situation and implement preparedness plans. The focus is on protecting vulnerable groups and ensuring that health services are ready to manage potential increases in respiratory issues. Officials have emphasized the importance of public risk communication, advising residents and travelers to check air quality levels before engaging in outdoor activities.
Health authorities have directed regional health offices to establish screening systems, provide health consultations, and identify safe zones for the public. While the Ministry is actively coordinating with local agencies to mitigate health impacts, the exact severity and duration of the pollution spikes remain subject to meteorological conditions. Residents and visitors are encouraged to stay informed through official health channels and take necessary precautions, particularly if they belong to high-risk groups sensitive to air quality changes.
