On 3 Feb 2026, Bangkok still recorded PM 2.5 exceeding the standard at the orange level in one area, Bang Rak District, with most air quality rated as moderate.
On 3 February, the Bangkok Air Quality Information Center reported the PM 2.5 situation from the city's air quality monitoring stations as of 07:00.
The 24-hour average PM 2.5 levels ranged from 19.9 to 39.4 micrograms per cubic meter (µg/m³). One area, Bang Rak District near the police booth in front of Bang Rak Lovely Plaza, exceeded the standard at the orange level—starting to affect health—with a reading of 39.4 µg/m³ (standard limit is 37.5 µg/m³).
Most Bangkok air quality stations recorded moderate air quality levels. The Meteorological Department forecasted partly cloudy skies over Bangkok.
Health advisory for orange-level air quality: beginning to impact health.
For the general public: use protective gear such as PM2.5 masks whenever outdoors, limit time spent on strenuous outdoor activities, and watch for symptoms like coughing, difficulty breathing, or eye irritation.
For at-risk groups: always wear PM2.5 masks outdoors, avoid strenuous outdoor activities, follow medical advice, and seek medical attention promptly if symptoms arise.
Relevant factors (forecasted weather conditions affecting PM 2.5 levels):
Between 3–11 Feb 2026, air ventilation is generally "good" with strong winds on some days. The atmospheric layer near the surface is relatively open, with rain possible on 8–9 Feb. Thus, dust accumulation is expected to decrease, with today's forecast partly cloudy.
Satellite hotspot data from NASA showed one abnormal heat spot detected in Bangkok on 2 February 2026 at 13:29 in Hua Mak subdistrict, Bang Kapi District. Authorities are coordinating to verify the hotspot.
The Environment Office has urged all relevant agencies to intensify efforts under the dust control action plan to reduce PM 2.5 severity and its health impacts, encouraging public and sector participation to change behaviors and reduce activities causing dust, 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 transportation.
5. Turn off engines when parked and maintain vehicles to prevent excessive black smoke.
If the public spots pollution sources, they can report tips via Traffy Fondue.
