Haze in Malaysia: What Expats Need to Know (and How to Stay Comfortable)

If this is your first haze season in Malaysia, the grey skies can be a little unsettling. The good news: it's a familiar seasonal event here, there's an official way to check the air quality any time, and a few simple habits make a big difference. Here's a calm, practical guide for expats and families.

What is the haze?

Most of the haze in Malaysia is smoke from land and forest fires that drifts across borders on the wind. It usually builds up during the drier southwest monsoon season, roughly mid-year to early autumn.

This October, Indonesian officials reported the largest number of fire hotspots in Central Kalimantan and South Sumatra, and the Malaysian and Indonesian governments have been in high-level contact about it (Malay Mail, 11 Oct 2026).

How to check the air quality

The Department of Environment (DOE) publishes official Air Pollutant Index (API) readings for monitoring stations across the country on its APIMS portal: apims.doe.gov.my. Find the station closest to your home, your office or your kids' school and make it a habit to check before outdoor plans.

What the API numbers mean

• 0–50: Good
• 51–100: Moderate
• 101–200: Unhealthy
• 201–300: Very unhealthy
• Over 300: Hazardous

During mid-October 2026, many areas in Johor, Selangor, Kuala Lumpur, Negeri Sembilan and Melaka sat in the "unhealthy" band, with a few stations briefly touching "very unhealthy" (Malay Mail, 18 Oct 2026).

Simple ways to stay comfortable on hazy days

• Check the API first before runs, hikes, sports or days out.
• Move workouts and kids' play indoors when readings are high: think gyms, indoor courts, malls and play centres.
• Keep windows and doors closed, and run an air purifier if you have one.
• Stay hydrated and drink plenty of water.
• Keep an eye on school notices. On 9 October, schools in several states moved to home-based learning because of the haze, and the Education Ministry has said future decisions will be announced earlier so parents can plan.

What the Ministry of Health advises

The Ministry of Health (MOH) says the most effective way to reduce the health effects of haze is to avoid outdoor activities, especially when the API is above 100. If you do need to be outside on unhealthy days, MOH suggests an N95 mask as an option because it filters fine PM2.5 particles; a three-ply mask gives only limited extra protection (Bernama, 15 Oct 2026).

Some people should take extra care and follow MOH advice closely: anyone with asthma, heart or lung conditions, older people, pregnant women and young children. If you or a family member feel unwell, see a doctor. MOH's haze information page is here: infosihat.moh.gov.my.

When will it clear?

MetMalaysia and the DOE expect conditions to improve as wind patterns change during the monsoon transition and the northeast monsoon arrives, bringing more rain from late October into November. Weather agencies have also said a viral "superhaze" claim is unlikely (The Rakyat Post, 15 Oct 2026).

So keep checking the API, take it easy on the hazy days, and enjoy the clear blue skies when they come back.
