If you live in Kuching or anywhere across western Sarawak right now, you know the feeling. You wake up, look out the window, and instead of the usual morning light, there’s a thick, acrid gray blanket hanging over the city. It isn't just unpleasant; it’s dangerous. As of August 21, 2026, the Sarawak Education Department has been forced to shut down 591 schools across 10 districts. Nearly 200,000 students are currently back to home-based learning because the air simply isn't safe to breathe.
This isn't a new story, but that makes it even more frustrating. We’ve seen this script before. Transboundary haze—smoke drifting from forest and peatland fires in neighboring Kalimantan—is once again turning our skies toxic. When the Air Pollutant Index (API) hits the "very unhealthy" threshold of 200, as it did in Serian, closing schools isn't just an administrative decision. It’s a necessary move to protect kids who shouldn't be inhaling particulate matter on their walk to class.
The Reality of Very Unhealthy Air
Most people don't fully grasp what a "very unhealthy" API reading actually means for their body. When the numbers climb past 200, you're dealing with a high concentration of PM2.5—tiny particles that bypass your body’s natural defenses and travel straight into your bloodstream.
I’ve been through enough of these haze seasons to know the immediate symptoms: the scratchy throat that doesn't go away, the stinging eyes, and the persistent, low-level fatigue. If you have any underlying respiratory issues like asthma, this isn't just an inconvenience; it’s a potential medical emergency.
The authorities are following the National Haze Action Plan, which mandates closures when the air reaches that critical 200 level. It’s a reactive measure, and honestly, that’s the hardest part to swallow. We are constantly stuck in a cycle of reacting to the smoke rather than getting ahead of it.
Why Kalimantan Fires Keep Bringing Smoke to Sarawak
You might be wondering why we’re taking the brunt of the hit. It comes down to basic geography and the monsoon winds. During the southwest monsoon, the prevailing winds act like a conveyor belt, carrying the smoke from thousands of hotspots in Indonesian Borneo directly toward our western coastline.
Data from the ASEAN Specialised Meteorological Centre (ASMC) is clear: between August 1 and August 19 alone, over 7,200 hotspots were detected in Kalimantan. Compare that to the mere 148 hotspots in Sarawak during the same period, and it’s obvious where the primary problem is coming from. While our local Natural Resources and Environment Board (NREB) is working hard to penalize open burning with fines up to RM100,000, the sheer volume of smoke drifting across the border makes it nearly impossible to control the local air quality.
Protecting Yourself Beyond School Closures
If you’re an adult trying to get through the work week or a parent managing kids at home, don't wait for an official alert to take action. I’ve learned that the "wait and see" approach usually ends with a headache.
- Stop the outdoor habit: If the API is above 100, skip the morning jog. It’s not worth the inflammation.
- Seal your space: Keep your windows closed. If you have an air purifier with a HEPA filter, run it 24/7 in your bedroom or living area.
- Upgrade your mask: A standard surgical mask isn't enough to stop fine particulates. You need an N95 or an FFP2 mask if you absolutely have to step outside.
- Hydration matters: Drink more water than you think you need. It helps your body flush out toxins and keeps your throat from drying out.
What Happens Next
The current school closures are a two-day measure, but don't count on everything being back to normal by Monday. The dry weather is expected to persist, and unless we get significant rainfall—which is hard to come by when the atmosphere is this parched—the haze could linger for weeks.
The Sarawak Education Department has already moved to home-based teaching and learning (PdPR) to keep the curriculum moving. If you’re a parent, expect to stay flexible. Check the official Department of Environment (DOE) portal at least twice a day. The situation can shift fast, and the last thing you want is to be caught off guard when the wind changes.
We’re in the middle of a long, dry season that likely won't let up until the end of September. Stay informed, keep your windows shut, and prioritize your health over your errands. This is the reality of living in this part of the world during the dry monsoon; treat it with the seriousness it deserves.
