Bangkok's air quality index from monitoring stations mostly indicates air quality at the level where health effects begin to appear.

The Meteorological Department forecasts partly cloudy weather in the Bangkok area.

Health recommendations for orange-level air quality: health effects begin to appear.

• General public: Use protective equipment such as PM 2.5 masks every time you go outside. Limit time spent on strenuous outdoor activities or exercise. Watch for symptoms like coughing, difficulty breathing, or eye irritation.
• Vulnerable groups: Use protective equipment such as PM 2.5 masks whenever outdoors. Avoid strenuous outdoor activities or exercise. Follow medical advice and seek medical attention promptly if symptoms occur.

Related factors (weather forecast trends affecting PM 2.5 pollution based on meteorological conditions):

Between 19-26 Feb, ventilation is classified as "good" while the atmospheric layer near the surface is characterized byalternating open and closed conditions, influenced bysouthern winds andthere is a chance of rainfall,which reduces dust accumulation. Today's forecast is partly cloudy.

Satellite data from NASA monitoring hotspots detected one abnormal heat spot on 18 Feb 2026 at 21:22 in Lam Toiting subdistrict, Nong Chok district (authorities are coordinating to verify the hotspot).
