Puncak fire, October 2026 Puncak
The fire started on 2 October 2026 in Puncak, Indonesia, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,546 hectares from heat detections, spread across a single municipality.
It is the 107th largest in Papua since 2016 (of 363 with a page). Number 334 in Indonesia in 2026, of 1005.
Is it still active?
No detections since 23 Oct 2026, 04:46 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 11 October 2026 the air beside the fire reached 96 µg/m³ of PM2.5. That day averaged 68: 4.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Puncak fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 2 October 2026 to 22 October 2026 (21 days). The perimeter dates it from 4 October 2026 to 22 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,546 hectares (35.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Puncak (3,571 ha, 0.4 %).
- Is the Puncak fire still active?
- No fire detections since 23 Oct 2026, 04:46 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 19.0 °C, humidity dropped to 26 % and gusts hit 38 km/h. The fire danger index (FWI) reached 3, class Very low.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Indonesia (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.
Emergency number: 112

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
