Middle Fly District fire, 17 October 2026 Middle Fly District

Dying down · last detection 6 Nov 2026, 04:48 UTC

The fire started on 17 October 2026 in Middle Fly District, Papua New Guinea, and satellites saw it burning for 21 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,539 hectares from heat detections, spread across a single municipality.

Number 81 in Papua New Guinea in 2026, of 196.

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.

Is it still active?

No detections since 6 Nov 2026, 04:48 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.

Frequently asked questions

How long did the Middle Fly District fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 17 October 2026 to 6 November 2026 (21 days). The perimeter dates it from 24 October 2026 to 6 November 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,539 hectares (35.4 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Middle Fly District (3,570 ha, 0.1 %).
Is the Middle Fly District fire still active?
No fire detections since 6 Nov 2026, 04:48 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 37.1 °C, humidity dropped to 26 % and gusts hit 40 km/h. The fire danger index (FWI) reached 35, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Papua New Guinea (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.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 24 October 2026 to 6 November 2026. 105 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.

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.
