Chiang Rai has stable air quality, but cool nights mean an extra jacket may be necessary. Bangkok continues to have problems with high pollution levels, and residents should limit their outdoor exposure. Phuket has an improved situation with good air quality on Sunday.

Air quality in Bangkok is slightly better than the previous week but is still unhealthy. Chiang Rai and Phuket remain relatively stable, with a slight improvement in Phuket.

What does AQI mean?

AQI (Air Quality Index) is an index that shows how healthy or unhealthy the air is. The higher the value, the worse the air quality. Values ​​above 100 can negatively affect sensitive groups.
