Common questions: Seremban API

What is the API in Seremban right now?
The API in Seremban is 60 (Moderate) as of 06:00 MYT, 4 Nov, read at the Department of Environment's Seremban, NEGERI SEMBILAN station. Sensitive people (asthma, elderly, children) should cut back on long or strenuous outdoor activity.
Which station represents Seremban?
Seremban's reading here comes from the Department of Environment's Seremban, NEGERI SEMBILAN station (CA24N), 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 Seremban tomorrow?
The Open-Meteo (CAMS) model puts tomorrow's API at around 27 (Good). That is a modelled forecast, not an official Department of Environment reading.
What has the highest reading in Seremban been lately?
Over the last 30 days, the highest reading was 189 on 8 Oct. The daily average across that period was around 129.
Are schools in Seremban 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 60 is well below that level.
When is haze season in Seremban?
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.
