Madera fire, 21 June 2019 Madera
The fire started on 21 June 2019 in Madera, Mexico, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,934 hectares from heat detections, spread across a single municipality.
It is the 99th largest in Chihuahua since 2016 (of 235 with a page). Number 143 in Mexico in 2019, of 364.

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 7 days without rain (1 mm or more) when it started. Rain came after the fire: 5.9 mm on 1 Jul.
This area had burned before
18% of the perimeter overlaps earlier fires recorded since 2016: 603 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 537 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 22 June 2019 and burned 2,305 ha (the satellite measured 2,934 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

Frequently asked questions
- How long did the Madera fire last?
- GWIS (Copernicus) dates it between 21 June 2019 and 27 June 2019: 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 2,934 hectares (29.3 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Madera (2,942 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 33.6 °C, humidity dropped to 15 % and gusts hit 59 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.
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.

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.
