Chiang Mai burning season in March: fly or skip?
I might still be in the north then. I need the air fork, not a temple list.
March is the month to move if you can
| If | Lean | Not |
|---|---|---|
| Asthma, small kids, or the trip is trekking | Move the month if you can. Burning season is the dated page | Treating March as “secret low season” |
| Indoor week, you can watch a daily AQI | Many people still go. Mask outdoors when the index is ugly | A ridge hike because the hotel photo was blue |
| You can only travel March | Cancellable bed. IQAir / a live PM2.5 map the week you fly | A 2019 “it clears for Songkran” blog |
| You meant Bangkok or the islands | Different pollution story. This is the valley | Cancelling Phuket because Chiang Mai was in the news |
2026 had documented ugly days (IQAir 4 Mar; Nation AQI 231 on 2 Apr; NASA still imaged valley smoke 22 Apr). It was not every day. August is not this. Not medical advice.
Month, and whether you can sit inside.
