Related factors (forecast meteorological conditions affecting PM 2.5) from 22-24 Jan 2026: Air ventilation conditions are "weak/good" while the atmospheric layer near the surface is relatively closed but with strong winds, so PM 2.5 concentration is expected to decrease. The forecast for today is cool mornings with strong winds and temperatures dropping 1-2 degrees Celsius.
Satellite hotspot data from NASA shows no abnormal heat spots indicating unusual heat on the surface in the Bangkok area.
The Environmental Office has coordinated with all relevant agencies to intensify operations under the PM 2.5 dust mitigation plan to reduce the severity of dust pollution and its potential health impacts. The office also encourages public and sector participation by changing behaviors and reducing activities that generate dust. The "5 Ways to Reduce Dust You Can Do" are: 1. Regularly clean your home by dust wiping; 2. Avoid burning trash and incense; 3. Plant trees to absorb pollution and trap dust; 4. Use public transportation; 5. Turn off vehicle engines when parked and maintain engines to prevent excessive black smoke.
