Namtumbo fire, 19 October 2026 Tunduru, Namtumbo

Out · last detection 29 Oct 2026, 22:46 UTC

Satellites first detected fire on 19 October 2026 in Namtumbo, Tanzania. It was active for 10 days, with 303 heat detections and an area with fire of about 3,878 hectares rebuilt from them, spread across 2 municipalities.

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

GWIS (Copernicus) has not yet published the perimeter of this fire. It rebuilds it from hotspots, which can take several days, and it does not always arrive. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). If the perimeter arrives, this page picks it up on its own and keeps the same address.

Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. The distance runs from the point marking the centre of each area 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.

Frequently asked questions

How long did the Namtumbo fire last?
According to the heat detections seen by satellite, it burned from 19 October 2026 to 28 October 2026 (10 days between the first and the last detection). There is no perimeter yet to date it.
How much area did it burn?
There is no perimeter yet. Heat detections rebuild about 3,878 hectares with fire (38.8 km²), a rough figure; GWIS will give its own when it publishes the perimeter, which can take several days.
Which municipalities burned?
The fire entered 2 municipalities: Tunduru (2,576 ha, 0.1 %); Namtumbo (1,302 ha, 0.1 %).
Is the Namtumbo fire still active?
No fire detections since 29 Oct 2026, 22:46 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 35.5 °C, humidity dropped to 22 % and gusts hit 40 km/h. The fire danger index (FWI) reached 42, class Very 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.

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
  • No perimeter yet: the area (≈ 3,878 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
  • Dates of the first and last VIIRS detection of the cluster. 303 Suomi-NPP VIIRS detections on those dates.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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.
