Fires in Kalimantan and Singapore's haze

Kalimantan (Indonesian Borneo) is more than 1,000 km east of Singapore. Its smoke tends to reach Singapore and Malaysia when winds blow from the east or south-east, and it often affects Sarawak and Brunei first.

'Upwind' is a wind-direction heuristic: it says transport is likely, not proven, and is not a smoke-trajectory model.

Why this region matters

Kalimantan has extensive peatland and forest-clearing fires in dry years, and in 2026 it has had the largest share of detections in our box.

Its distance and the usual wind pattern mean it is often a regional contributor rather than the direct cause of Singapore's air on a given day.

A note on our region box

The box is approximate and its northern edge may include a little of Sarawak. Treat counts as orientation, not an official tally.
