Fires in South Sumatra and Singapore's haze

South Sumatra is roughly 550 km south of Singapore. It is a major fire region in dry years; southerly winds, which are common in the dry season, can carry its smoke north toward Singapore and Peninsular Malaysia.

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

Why this region matters

Large peat and plantation landscapes in provinces such as South Sumatra are prone to burning when dry, and fires there are often among the largest in Sumatra.

Because it lies due south of Singapore, a south wind is the pattern that links it to Singapore's air.

How we read the data

Same method as other regions: FIRMS detections in an approximate box, last 24 hours versus the previous 24 hours, and a check of whether the 1.5 km wind blows from that direction.

A high count with a wind that is not blowing toward you does not mean haze is coming; a modest count with a steady wind can matter more.
