Dilly fire, 23 October 2026 Dilly, Ouagadou
The fire started on 23 October 2026 in Dilly, Mali, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,168 hectares from heat detections, spread across 2 municipalities.
It is the 97th largest in Koulikouro since 2016 (of 127 with a page). Number 124 in Mali in 2026, of 154.

Is it still active?
No detections since 27 Oct 2026, 13:46 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.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 2 days without rain (1 mm or more) when it started.
This area had burned before
75% of the perimeter overlaps earlier fires recorded since 2016: 456 ha in 2018, 69 ha in 2021, 198 ha in 2023, 91 ha in 2024, 1,131 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,623 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 23 October 2026 the air beside the fire reached 42 µg/m³ of PM2.5. That day averaged 32: 2.1 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Dilly fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 23 October 2026 to 27 October 2026 (5 days). The perimeter dates it from 25 October 2026 to 27 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,168 hectares (21.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Dilly (1,834 ha, 0.3 %); Ouagadou (344 ha, 0.3 %).
- Is the Dilly fire still active?
- No fire detections since 27 Oct 2026, 13:46 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 39.4 °C, humidity dropped to 14 % and gusts hit 42 km/h. The fire danger index (FWI) reached 46, class Very high.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mali (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 25 October 2026 to 27 October 2026. 18 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.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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 ADM3 (Creative Commons Attribution 4.0 International (CC BY 4.0)). 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.
