How long did the Fakfak fire last?

According to the heat detections seen by satellite inside the perimeter, it burned from 31 August 2026 to 31 October 2026 (62 days). The perimeter dates it from 6 September 2026 to 26 October 2026.

How much area did it burn?

The perimeter GWIS (Copernicus) rebuilt from heat detections is 28,896 hectares (289.0 km²). It is an estimate: official national figures may differ.

Which municipalities burned?

The fire entered 2 municipalities: Fakfak (23,933 ha, 2.2 %); Kaimana (4,702 ha, 0.3 %).

Is the Fakfak fire still active?

No fire detections since 30 Oct 2026, 16:22 UTC. A lack of detections is not an official extinction.

What was the weather like?

During the fire the temperature reached 29.6 °C, humidity dropped to 56 % and gusts hit 49 km/h. The fire danger index (FWI) reached 0, 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.

Fakfak fire, 31 August 2026 Fakfak, Kaimana

Out · last detection 30 Oct 2026, 16:22 UTC

The fire started on 31 August 2026 in Fakfak, Indonesia, and satellites saw it burning for 62 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 28,896 hectares from heat detections, spread across 2 municipalities.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

The power measured by the satellite is low (12.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Fakfak fire last?: According to the heat detections seen by satellite inside the perimeter, it burned from 31 August 2026 to 31 October 2026 (62 days). The perimeter dates it from 6 September 2026 to 26 October 2026.
How much area did it burn?: The perimeter GWIS (Copernicus) rebuilt from heat detections is 28,896 hectares (289.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?: The fire entered 2 municipalities: Fakfak (23,933 ha, 2.2 %); Kaimana (4,702 ha, 0.3 %).
Is the Fakfak fire still active?: No fire detections since 30 Oct 2026, 16:22 UTC. A lack of detections is not an official extinction.
What was the weather like?: During the fire the temperature reached 29.6 °C, humidity dropped to 56 % and gusts hit 49 km/h. The fire danger index (FWI) reached 0, 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.

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.

How we know this

Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 4 polygons grouped in this page.
Dates adjusted with the VIIRS detections inside the perimeter, which said 6 September 2026 to 26 October 2026. 646 Suomi-NPP VIIRS detections on those dates.
We have not matched this page with any official record.
Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives. No FWI: there are fewer than 30 days of data before the start.

How we build fire pages: methodology

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.
