Highest station reading in Perak each hour, on the US EPA AQI scale. A break in the line is an hour with no reporting station, not a reading of zero.
The highest reading recorded in Perak on each day, Malaysian time. Days with no reporting station are absent rather than shown as zero.

What drives air quality in Perak
Why this state’s readings move the way they do.
Perak stretches from the Thai border down to Selangor, with the Kinta Valley and Ipoh at its centre. Ipoh sits in a limestone basin ringed by hills, which can hold air in place on still days, and the valley’s quarrying and cement industry adds a local source that most other states do not have.
Main local sources
- Limestone quarrying and cement production in the Kinta Valley
- The Ipoh basin’s hill-ringed geography, which limits dispersal on still days
- Transboundary haze reaching the west coast and Lumut
- Plantation and land-clearing fires during dry spells
How the year runs here
Perak is exposed during the June–September southwest monsoon like the rest of the west coast, and its inland basin can hold a bad day longer than a coastal station would.
Readings on this page cover Ipoh, Taiping, Teluk Intan, Lumut, Sitiawan and Kuala Kangsar, to the extent that stations in those areas are reporting. Each figure is named with the station it came from, so you can judge how close it is to you.
Jerebu and haze in Perak
When the air here crosses into unhealthy territory, we write it up.
We publish a dated bulletin for every day on which any Malaysian state reaches AQI 101 or above — the point at which health advice starts naming who should stay indoors. The bulletins are built from the same hourly archive as the charts above, so they record what the stations actually read rather than restating a headline.
Perak has had 13 such days in the last 14.

Asked about this state specifically.
Why does Ipoh’s air sometimes stay bad after the rest of the state clears?
Ipoh sits in the Kinta Valley, a basin ringed by limestone hills. On a still day there is less wind to move air out of the valley than there is along the coast, so whatever is in it — local dust, traffic, or haze that has already arrived — can linger longer.
Are Thai stations counted in Perak’s reading?
No. Perak borders Thailand at its northern tip and stations across that border do appear in the raw data we request, including Betong in Yala. Each station is tested against the actual state boundary, so only stations genuinely inside Perak count towards the figure here.
For how the index is calculated, why it differs from Malaysia’s official API, and where the data comes from, see the national air quality page.
