Common questions: Alor Setar API

What is the API in Alor Setar right now?
The API in Alor Setar is 39 (Good) as of 06:00 MYT, 4 Nov, read at the Department of Environment's Alor Setar, KEDAH station. Air quality is good. Outdoor activity as usual.
Which station represents Alor Setar?
Alor Setar's reading here comes from the Department of Environment's Alor Setar, KEDAH station (CA03K), about 3 km from the city centre. One station does not represent a whole city, so other parts of it can read differently.
What will the haze be like in Alor Setar tomorrow?
The Open-Meteo (CAMS) model puts tomorrow's API at around 40 (Good). That is a modelled forecast, not an official Department of Environment reading.
What has the highest reading in Alor Setar been lately?
Over the last 30 days, the highest reading was 153 on 9 Oct. The daily average across that period was around 53.
Are schools in Alor Setar closed because of haze?
Since October 2026, schools in an affected area close when the API goes above 180, or stays above 150 for three days in a row, on the instruction of the Ministry of Education or the State Education Department, not from this number alone. The current reading of 39 is well below that level.
When is haze season in Alor Setar?
The Peninsula's west coast has two risky windows: February to April, when haze is more local, and July to October, the worst window, when the southwest monsoon carries smoke from regional forest and peatland fires. El Niño years are usually worse.
