Related factors (weather forecast trends affecting PM2.5 levels meteorologically):
Between 27-28 Jan 2026, air ventilation is weak, with a closed atmospheric layer near the surface, causing dust to accumulate. From 29 Jan to 4 Feb, the surface atmospheric layer alternates between open and closed, influenced by southerly winds from the Gulf of Thailand, reducing dust accumulation. Today’s forecast is cold with some morning fog.
Satellite hotspot data from NASA shows no abnormal heat spots detected over Bangkok.
The Environment Office has coordinated with all relevant agencies to intensify operations under the dust pollution action plan to mitigate PM2.5 severity and its health impacts. It also encourages public participation to change behaviors and reduce dust-generating activities by following “5 ways to reduce dust you can do”: 1. Regularly clean homes by dust wiping, 2. Avoid burning waste or incense, 3. Plant trees to absorb pollution and trap dust, 4. Use public transport, and 5. Turn off engines when parked and maintain vehicles to prevent excessive black smoke.
