Reading the report

What a week of
air quality tells us.

A closer look at Malaysia's Air Pollutant Index, known locally as Indeks Pencemaran Udara or IPU.

Malaysia's weekly API in context

This report covers 7 – 13 Oct 2026, the latest Wednesday-to-Tuesday reporting week in Malaysia Time. The national weekly average of 110.8 API falls in the Unhealthy category. On Tuesday, the final day's data is partial until all hourly readings arrive. It summarises the period across reporting stations; it does not describe every place at every hour.

Why averages and peaks tell different stories

A weekly average shows the level across the available readings. A peak is the highest single reading during that period, so a short rise at one station can stand out even when the weekly average is lower. For this report, the highest value is 211 API at Batu Pahat in Johor. Compare the solid average line with the station peak and min–max range to see that difference.

Comparing states, stations and cities

State averages combine station averages in proportion to their reading counts. Stations with more observations contribute more to the result. City summaries use a representative monitoring station, named below each city. That station describes its monitoring location; readings can differ elsewhere in the city.

Where these numbers come from

This report uses 11,424 stored hourly readings from 68 reporting stations. The archive collects the Department of Environment Malaysia's APIMS feed. Coverage depends on the readings received during the reporting window. Missing observations can affect comparisons between places and periods.

Soalan lazim berkenaan jerebu dan kualiti udara Malaysia

What was Malaysia's average air quality during the latest reporting week?

Across 7 – 13 Oct 2026, Malaysia averaged an Air Pollutant Index of 110.8, which sits in the Unhealthy band (Tidak Sihat). 58% of all hourly readings stayed within Good or Moderate.

Where was the cleanest air recorded?

How is this report put together?

Hourly readings are collected from the Department of Environment's APIMS feed for all 68 national stations and stored as they arrive. The report advances to a new Wednesday-to-Tuesday period each Tuesday in Malaysia Time and refreshes hourly. On Tuesday, readings for the final day accumulate as they arrive. State figures weight each station by how many hours it actually reported.
