Air Quality Index from Bangkok's monitoring stations mostly falls in the level indicating air quality beginning to impact health.
The Meteorological Department forecasts Bangkok's weather as cool with some morning fog, followed by a slight temperature increase.
Health advisory: Orange level air quality means health impacts are beginning.
Related factors (forecast of weather conditions affecting PM 2.5): From 30 Jan to 3 Feb 2026, air ventilation is expected to be "weak/good" with the surface atmospheric layer alternating between open and closed, influenced by southern winds from the Gulf of Thailand, reducing dust accumulation. The forecast for today is cool with some morning fog and a slight temperature rise.
Satellite data from NASA on detected hotspots show no abnormal heat signatures indicating fires within Bangkok's area.
The Environment Office has coordinated with all relevant agencies to tighten operations under the dust problem action plan to alleviate the severity of PM2.5 pollution and its potential health impacts. It also encourages public and sector participation by changing behaviors and reducing dust-generating activities, promoting “5 Ways to Reduce Dust You Can Do”: 1. Regularly clean your home by dusting 2. Avoid burning trash and incense 3. Plant trees to absorb pollution and trap dust 4. Use public transport 5. Turn off engines when parked and maintain engines to prevent excessive black smoke.
Warnings and public announcements encourage people to check air quality information before leaving home via:
If citizens spot pollution sources, they can report tips through Traffy Fondue.
