Kilosa fire, 13 October 2026 Kilosa

Dying down · last detection 30 Oct 2026, 11:21 UTC

The fire started on 13 October 2026 in Kilosa, Tanzania, and satellites saw it burning for 18 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 4,293 hectares from heat detections, spread across a single municipality.

It is the 84th largest in Morogoro since 2016 (of 145 with a page). Number 113 in Tanzania in 2026, of 218.

Is it still active?

No detections since 30 Oct 2026, 11:21 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.

It had gone 5 days without rain (1 mm or more) when it started.

This area had burned before

82% of the perimeter overlaps earlier fires recorded since 2016: 1,548 ha in 2016, 824 ha in 2021, 1,937 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 3,512 ha that had burned before.

How big is it?

It burned the equivalent of 2.7% of the area of London (43 km² against 1,583 km²).

Frequently asked questions

How long did the Kilosa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 13 October 2026 to 30 October 2026 (18 days). The perimeter dates it from 20 October 2026 to 30 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 4,293 hectares (42.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Kilosa (4,324 ha, 0.4 %).
Is the Kilosa fire still active?
No fire detections since 30 Oct 2026, 11:21 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 35.7 °C, humidity dropped to 28 % and gusts hit 42 km/h. The fire danger index (FWI) reached 28, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Tanzania (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.

What do you think is wrong?

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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 20 October 2026 to 30 October 2026. 87 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.

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.
