Wildfires in Indonesia in 2026

979 fires larger than 1,500 hectares in Indonesia in 2026, with 4,482,122 hectares burned according to their perimeters. Here is the whole year: what the official record says, when and where it burned and what the weather was like.

Only fires of 1,500 ha or more get an entry: smaller ones are not in the lists or the entry totals, but they are in the GWIS yearly series.

These figures leave out 14 provisional pages, seen only as heat detections and still without a perimeter; 70 pages with faulty data, under review. They appear in the lists, marked.

Year in progress: the figures change every day until the year closes and are not compared with complete years.

Series not comparable from October 2025 onwards: GWIS changed its near-real-time perimeters.

The year in a few sentences

  1. Up to 4 November, Copernicus GWIS counts 8,755,761 hectares burned in Indonesia in 2026: 2.6 times the average for the same weeks from 2012 to 2025 (3,417,683 ha). GWIS estimates for the current year are provisional and may change.

  2. The worst week so far was 10 September to 16 September: 952,340 hectares burned in seven days, 11% of the year to date according to Copernicus GWIS.

  3. The largest fire was the Ketapang fire, which started on 25 July 2026 and burned 131,352 hectares: 3% of the area of the year's 979 fires with a page.

Burned area in 2026 (Copernicus Land, Sentinel-3)

According to Copernicus Land, 109,689 ha burned in 2026 (Jan–May). The year is not complete, so it is not compared with the others.

The area the Sentinel-3 satellite sees burned each month, separate from the fire pages. It is the same source and the same method every year, so years can be compared with each other. It counts everything that burns, including crop and pasture burning, which is why it does not match the fire pages or the official statistics.

Fire-page areas are satellite-measured perimeters and may differ from official statistics. The yearly and weekly record is the Copernicus GWIS estimate. The FWI is our own calculation from ERA5 at each fire's location: it is not an official danger warning.

Perimeters: Copernicus EFFIS and GWIS (and MTBS, NIFC or NBAC in North America). Hotspots: NASA FIRMS (VIIRS). Weather: Copernicus ERA5 via Open-Meteo. How it is calculated
