Oti fire, 22 January 2026 Oti
The fire started on 22 January 2026 in Oti, Togo, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,213 hectares from heat detections, spread across a single municipality.
It is the largest fire in Savanes since 2016 (of 78 with a page). Number 6 in Togo in 2026, of 54.

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 27 January 2026 the air beside the fire reached 86 µg/m³ of PM2.5. That day averaged 68: 4.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Oti fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 22 January 2026 to 31 January 2026 (10 days). The perimeter dates it from 24 January 2026 to 27 January 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,213 hectares (52.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Oti (5,248 ha, 1.2 %).
- What was the weather like?
- During the fire the temperature reached 38.6 °C, humidity dropped to 7 % and gusts hit 43 km/h. The fire danger index (FWI) reached 65, class Extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Togo (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.
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.

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-ShareAlike 2.0). 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.
