Muñoz fire, 24 March 2023 Muñoz
The fire started on 24 March 2023 in Muñoz, Venezuela, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,948 hectares from heat detections, spread across a single municipality.
It is the 277th largest in Apure since 2016 (of 919 with a page). Number 44 in Venezuela in 2023, of 193.

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 12 days without rain (1 mm or more) when it started. Rain came after the fire: 4.4 mm on 1 Apr.
This area had burned before
19% of the perimeter overlaps earlier fires recorded since 2016: 82 ha in 2016, 56 ha in 2019, 442 ha in 2020, 312 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 574 ha that had burned before.

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 March 2023 the air beside the fire reached 80 µg/m³ of PM2.5. That day averaged 36: 2.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Muñoz fire last?
- GWIS (Copernicus) dates it between 24 March 2023 and 28 March 2023: 5 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 2,948 hectares (29.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Muñoz (2,969 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 37.5 °C, humidity dropped to 24 % and gusts hit 44 km/h. The fire danger index (FWI) reached 36, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Venezuela (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 (Open Data Commons Open Database License 1.0). 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.
