Balleza fire, 20 May 2024 Balleza

Out · last detection 29 May 2024, 09:27 UTC

The fire started on 20 May 2024 in Balleza, Mexico, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,913 hectares from heat detections, spread across a single municipality. According to CONAFOR, it was detected on 20 May 2024 and declared extinguished on 29 May 2024.

It is the 68th largest in Chihuahua since 2016 (of 234 with a page). Number 74 in Mexico in 2024, of 289.

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.

Residents< 20

Inside 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.

Official record

According to CONAFOR, this fire started on 20 May 2024 and burned 3,620 ha (the satellite measured 3,913 ha).

Frequently asked questions

How long did the Balleza fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 20 May 2024 to 29 May 2024 (10 days). The perimeter dates it from 20 May 2024 to 28 May 2024. According to CONAFOR, it was detected on 20 May 2024 and declared extinguished on 29 May 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,913 hectares (39.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Balleza (3,926 ha, 0.7 %).
What was the weather like?
During the fire the temperature reached 33.0 °C, humidity dropped to 11 % and gusts hit 63 km/h. The fire danger index (FWI) reached 66, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Mexico (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 20 May 2024 to 28 May 2024. 323 Suomi-NPP VIIRS detections on those dates.
  • Compared with CONAFOR: 3,620 official ha against 3,913 ha of perimeter; they agree within 25%.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • 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 ADM2 (Creative Commons Attribution 4.0 (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.
