Huamuxtitlán fire, March 2024 Zapotitlán Lagunas, Huamuxtitlán
The fire started on 7 March 2024 in Huamuxtitlán, Mexico, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,544 hectares from heat detections, spread across 2 municipalities. According to CONAFOR, the largest of the 2 recorded fires was detected on 7 March 2024 and declared extinguished on 20 March 2024.
It is the 590th largest in Guerrero since 2016 (of 612 with a page). Number 280 in Mexico in 2024, of 289.

This area had burned before
72% of the perimeter overlaps earlier fires recorded since 2016: 907 ha in 2018, 655 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,119 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.

Complex of 2 fires according to CONAFOR
According to CONAFOR, 2 fires started inside this perimeter on these dates, totalling 1,838 ha (the satellite measured 1,544 ha).
CONAFOR records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.

Total according to CONAFOR: 1,838 ha, 119 % of the 1,544 ha in the satellite perimeter.

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 Huamuxtitlán fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 March 2024 to 18 March 2024 (12 days). The perimeter dates it from 7 March 2024 to 14 March 2024. According to CONAFOR, the largest of the 2 recorded fires was detected on 7 March 2024 and declared extinguished on 20 March 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,544 hectares (15.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Zapotitlán Lagunas (855 ha, 2.8 %); Huamuxtitlán (696 ha, 2.5 %).
- What was the weather like?
- During the fire the temperature reached 33.4 °C, humidity dropped to 18 % and gusts hit 46 km/h. The fire danger index (FWI) reached 40, class Very high.
- 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 7 March 2024 to 14 March 2024. 68 Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 1,838 official ha against 1,544 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.
