Match the reading to the location
A city or province can contain several stations with different surroundings. Use the station name and map position rather than treating one reading as the condition everywhere in the area.
Air4Thai air-quality station data
Air4Thai publishes Thailand PM2.5, PM10 and AQI readings by monitoring station. Open the official service, choose a station near the place that matters and check its observation time.
Check time and availability
Read the observation timestamp with the PM2.5, PM10 or AQI value. A stale value or missing station is an unresolved current condition, not evidence that the air is clean.
Observation, not a personal forecast
Air4Thai reports monitored conditions. It does not guarantee the air at a hotel, trail or future travel time, and this independent profile does not relay live readings.
