Lékana fire, 22 July 2026 Lékana

Out · last detection 31 Jul 2026, 12:51 UTC

The fire started on 22 July 2026 in Lékana, Republic of the Congo, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 16,418 hectares from heat detections, spread across a single municipality.

It is the largest fire in Plateaux since 2016 (of 303 with a page). Number 2 in Republic of the Congo in 2026, of 360.

It had gone 6 days without rain (1 mm or more) when it started. Rain came after the fire: 1.4 mm on 4 Aug.

This area had burned before

59% of the perimeter overlaps earlier fires recorded since 2016: 1,658 ha in 2017, 1,053 ha in 2019, 2,732 ha in 2020, 455 ha in 2021, 3,515 ha in 2022, 2,199 ha in 2023, 2,956 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 9,741 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 10% of the area of London (164 km² against 1,583 km²).

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 Lékana fire last?
GWIS (Copernicus) dates it between 22 July 2026 and 31 July 2026: 10 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 16,418 hectares (164.2 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Lékana (15,882 ha, 3.6 %).
What was the weather like?
During the fire the temperature reached 28.6 °C, humidity dropped to 59 % and gusts hit 36 km/h. The fire danger index (FWI) reached 17, class Moderate.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Republic of the Congo (geoBoundaries ADM2). 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; 2 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 247 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.

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 (Map Library 2007, nombres de Wikidata) (Public Domain). 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.
