The fire started on 3 April 2024 in Jiquipilas, Mexico, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,306 hectares from heat detections, spread across a single municipality.
It is the 104th largest in Chiapas since 2016 (of 246 with a page). Number 151 in Mexico in 2024, of 289.

93% of the perimeter overlaps earlier fires recorded since 2016: 298 ha in 2016, 496 ha in 2018, 2,151 ha in 2019, 476 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 2,156 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.

Residents≈ 250
Inside the perimeter there were about 3.0 hectares of built-up land and about 250 residents (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.
According to CONAFOR, this fire started on 6 April 2024 and burned 4,992 ha (the satellite measured 2,306 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

How a twin is chosen
Same area: fires that have already ended, less than 250 km from this one, since 2016.
Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
They are sorted by similarity, and the outlines of the first five are drawn.

⬇ Download CSVTimes in UTC. Each detection is a 375 m pixel: a large fire yields hundreds per pass.
According to the heat detections seen by satellite inside the perimeter, it burned from 3 April 2024 to 17 April 2024 (15 days). The perimeter dates it from 6 April 2024 to 11 April 2024.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,306 hectares (23.1 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Jiquipilas (2,318 ha, 1.8 %).
What was the weather like?
During the fire the temperature reached 36.3 °C, humidity dropped to 31 % and gusts hit 80 km/h. The fire danger index (FWI) reached 45, 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 39. Their median duration was 7 days and their median area 2,120 ha; 100 % went past 1,000 ha. In 18 of 39, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 1.3 mm.
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.
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.
⚑Report an errorHow 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 6 April 2024 to 11 April 2024. 145 Suomi-NPP VIIRS detections on those dates.
Compared with CONAFOR: 4,992 official ha against 2,306 ha of perimeter; similar, but with reservations.
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.
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.
