Manyoni fire, 28 June 2021 Manyoni
The fire started on 28 June 2021 in Manyoni, Tanzania, and satellites saw it burning for 13 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,000 hectares from heat detections, spread across a single municipality.
It is the 124th largest in Singida since 2016 (of 124 with a page). Number 135 in Tanzania in 2021, of 135.

The weather it burned in
It had gone 51 days without rain (1 mm or more) when it started.
This area had burned before
96% of the perimeter overlaps earlier fires recorded since 2016: 2,398 ha in 2016, 906 ha in 2017, 1,050 ha in 2018, 1,328 ha in 2019, 348 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 2,867 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. 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 Manyoni fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 June 2021 to 10 July 2021 (13 days). The perimeter dates it from 1 July 2021 to 7 July 2021.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,000 hectares (30.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Manyoni (3,024 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 27.6 °C, humidity dropped to 27 % and gusts hit 42 km/h. The fire danger index (FWI) reached 36, 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.

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 1 July 2021 to 7 July 2021. 111 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.
