Common questions: Selangor API

What is the API in Selangor right now?
The highest reading in Selangor is 75 (Moderate) at the JOHAN SETIA station, as of 06:00 MYT, 4 Nov. Sensitive people (asthma, elderly, children) should cut back on long or strenuous outdoor activity.
How many stations monitor Selangor?

Are schools in Selangor 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 75 is well below that level.
When is haze season in Selangor?
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.
