Common questions: Miri API

What is the API in Miri right now?
The API in Miri is 40 (Good) as of 06:00 MYT, 4 Nov, read at the Department of Environment's Miri, SARAWAK station. Air quality is good. Outdoor activity as usual.
Which station represents Miri?
Miri's reading here comes from the Department of Environment's Miri, SARAWAK station (CA56Q), about 4 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 Miri tomorrow?
The Open-Meteo (CAMS) model puts tomorrow's API at around 26 (Good). That is a modelled forecast, not an official Department of Environment reading.
What has the highest reading in Miri been lately?
Over the last 30 days, the highest reading was 104 on 11 Oct. The daily average across that period was around 62.
Are schools in Miri 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 40 is well below that level.
When is haze season in Miri?
In Sabah, Sarawak and Labuan, the riskiest window is July to October, when forest and peatland fires on Borneo and across the region peak. El Niño years are usually worse, because dry peat catches fire more easily.
