Manyoni fire, 9 August 2026 Manyoni
The fire started on 9 August 2026 in Manyoni, Tanzania, and satellites saw it burning for 23 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 21,611 hectares from heat detections, spread across a single municipality.
It is the 4th largest in Singida since 2016 (of 124 with a page). Number 8 in Tanzania in 2026, of 200.

The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started.
This area had burned before
81% of the perimeter overlaps earlier fires recorded since 2016: 3,102 ha in 2016, 3,398 ha in 2017, 1,682 ha in 2018, 655 ha in 2019, 7,112 ha in 2020, 6,085 ha in 2021, 6,174 ha in 2022, 2,740 ha in 2023, 2,971 ha in 2024, 1,495 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 17,460 ha that had burned before.

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 13 August 2026 the air beside the fire reached 33 µg/m³ of PM2.5. That day averaged 24: 1.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Manyoni fire last?
- GWIS (Copernicus) dates it between 9 August 2026 and 31 August 2026: 23 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 21,611 hectares (216.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Manyoni (21,787 ha, 0.8 %).
- What was the weather like?
- During the fire the temperature reached 28.9 °C, humidity dropped to 19 % and gusts hit 43 km/h. The fire danger index (FWI) reached 41, 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.
Emergency number: 112
Satellite cross-check
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.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 566 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
