Tepic fire, May 2024 Tepic
The fire started on 11 May 2024 in Tepic, Mexico, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,878 hectares from heat detections, spread across a single municipality.
It is the 23th largest in Nayarit since 2016 (of 179 with a page). Number 37 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 more than two months without rain (1 mm or more) when it started.
This area had burned before
95% of the perimeter overlaps earlier fires recorded since 2016: 2,306 ha in 2016, 5,405 ha in 2018, 3,651 ha in 2021. Part of it burned more than once, so the yearly figures add up to more than the 5,588 ha that had burned before.

What happened to each town

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
Official record
According to CONAFOR, this fire started on 10 May 2024 and burned 4,582 ha (the satellite measured 5,878 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

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.

The smoke
CAMS · CopernicusOn 11 May 2024 the air beside the fire reached 57 µg/m³ of PM2.5. That day averaged 29: 2.0 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Tepic fire last?
- GWIS (Copernicus) dates it between 11 May 2024 and 17 May 2024: 7 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 5,878 hectares (58.8 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Tepic (5,904 ha, 3.6 %).
- What was the weather like?
- During the fire the temperature reached 28.5 °C, humidity dropped to 31 % and gusts hit 39 km/h. The fire danger index (FWI) reached 31, class 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.
Emergency number: 911
Satellite cross-check
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.

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.
