Tecate fire, January 2025 Tecate
The fire started on 23 January 2025 in Tecate, Mexico, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,364 hectares from heat detections, spread across a single municipality.
It is the 22th largest in Baja California since 2016 (of 57 with a page). Number 55 in Mexico in 2025, of 167.

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 59 days without rain (1 mm or more) when it started. Rain came after the fire: 7.6 mm on 26 Jan.
This area had burned before
80% of the perimeter overlaps earlier fires recorded since 2016: 1,176 ha in 2019, 1,616 ha in 2020.
What happened to each town

3,375 ha reached on 23 Jan1.2 %
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.
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 25 January 2025 the air beside the fire reached 144 µg/m³ of PM2.5. That day averaged 68: 4.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Tecate fire last?
- GWIS (Copernicus) dates it between 23 January 2025 and 24 January 2025: 2 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 3,364 hectares (33.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Tecate (3,375 ha, 1.2 %).
- What was the weather like?
- During the fire the temperature reached 22.1 °C, humidity dropped to 2 % and gusts hit 100 km/h. The fire danger index (FWI) reached 77, class Very extreme.
- 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

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.
