Zirándaro fire, May 2024 Zirándaro
The fire started on 5 May 2024 in Zirándaro, Mexico, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,630 hectares from heat detections, spread across a single municipality.
It is the 563th largest in Guerrero since 2016 (of 612 with a page). Number 261 in Mexico in 2024, of 289.

This area had burned before
99% of the perimeter overlaps earlier fires recorded since 2016: 128 ha in 2020, 1,537 ha in 2021, 655 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,618 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 were about 0.17 hectares of 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 2 May 2024 and burned 2,478 ha (the satellite measured 1,630 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 11 May 2024 the air beside the fire reached 44 µg/m³ of PM2.5. That day averaged 34: 2.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Zirándaro fire last?
- GWIS (Copernicus) dates it between 5 May 2024 and 12 May 2024: 8 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 1,630 hectares (16.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Zirándaro (1,639 ha, 0.8 %).
- 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 from the perimeter: the VIIRS detections inside it did not change them. No Suomi-NPP VIIRS detections on those dates.
- Compared with CONAFOR: 2,478 official ha against 1,630 ha of perimeter; similar, but with reservations.
- 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.
