The air quality index from Bangkok monitoring stations mostly shows levels beginning to affect health.
The Meteorological Department forecasts cool weather with some morning fog in Bangkok.
Health Recommendations:
Red level air quality: Health effects expected.
All residents: Avoid outdoor activities. If outdoor activity is necessary, always use protective equipment such as PM 2.5 masks. Seek medical attention immediately if symptoms occur. People with chronic illnesses should stay in pollution-safe areas, prepare medications and necessary equipment, and strictly follow medical advice.
Orange level air quality: Beginning to affect health.
Related factors (forecast meteorological conditions affecting PM 2.5): On 28 Jan 2026, ventilation is "weak" with a relatively closed atmospheric layer near the ground, so PM levels mostly remain above standards. From 29 Jan to 5 Feb, ventilation is "weak/good" with alternating open and closed ground-level atmospheric layers influenced by southerly winds from the Gulf of Thailand, helping reduce dust accumulation. Today’s forecast is cool with some morning fog.
Satellite hotspot data from NASA shows no abnormal heat spots detected over Bangkok, indicating no unusual surface heat sources.
The Environment Office has coordinated with all relevant agencies to tighten enforcement of the dust control action plan to mitigate PM 2.5 severity and health impacts. It calls for public cooperation to change behaviors and reduce dust-generating activities by following "5 ways to reduce dust you can do": 1. Regular dust cleaning at home by wiping surfaces; 2. Avoid burning garbage or incense; 3. Plant trees to absorb pollutants and trap dust; 4. Use public transport; and 5. Turn off engines when parked and maintain vehicles to prevent excessive black smoke.
Public warnings and information dissemination encourage residents to check air quality before leaving home via:
If residents spot pollution sources, they can report tips via Traffy Fondue.
