La Yesca fire, May 2024 La Yesca
The fire started on 8 May 2024 in La Yesca, Mexico, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,846 hectares from heat detections, spread across a single municipality.
It is the 139th largest in Nayarit since 2016 (of 181 with a page). Number 217 in Mexico in 2024, of 289.

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 52 days without rain (1 mm or more) when it started.
This area had burned before
63% of the perimeter overlaps earlier fires recorded since 2016: 306 ha in 2016, 1,055 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 1,170 ha that had burned before.

What happened to each town

La Yesca where it started1,854 ha reached on 8 May0.4 %
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.

Official record
According to CONAFOR, this fire started on 8 May 2024 and burned 733 ha (the satellite measured 1,846 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

The smoke
CAMS · CopernicusOn 9 May 2024 the air beside the fire reached 103 µg/m³ of PM2.5. That day averaged 52: 3.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the La Yesca fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 8 May 2024 to 14 May 2024 (7 days). The perimeter dates it from 8 May 2024 to 12 May 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 1,846 hectares (18.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered La Yesca (1,854 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 36.6 °C, humidity dropped to 16 % and gusts hit 56 km/h. The fire danger index (FWI) reached 49, 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 8 May 2024 to 12 May 2024. 111 Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 733 official ha against 1,846 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.
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.
