Out · last detection 27 May 2023, 20:42 UTC

The fire started on 13 May 2023 in Ixtlán del Río, Mexico, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 9,486 hectares from heat detections, spread across 2 municipalities. According to CONAFOR, the largest of the 2 recorded fires was detected on 13 May 2023 and declared extinguished on 28 May 2023.

It is the 9th largest in Nayarit since 2016 (of 181 with a page). Number 13 in Mexico in 2023, of 285.

It had gone more than two months without rain (1 mm or more) when it started.

This area had burned before

70% of the perimeter overlaps earlier fires recorded since 2016: 3 ha in 2016, 1,710 ha in 2017, 5,844 ha in 2021, 178 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 6,639 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 6% of the area of London (95 km² against 1,583 km²).

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 2025
Built-up area0.17 ha
Residents< 20

Inside 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

Complex of 2 fires according to CONAFOR

According to CONAFOR, 2 fires started inside this perimeter on these dates, totalling 8,018 ha (the satellite measured 9,486 ha).

CONAFOR records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.

Frequently asked questions

How long did the Ixtlán del Río fire last?
GWIS (Copernicus) dates it between 13 May 2023 and 27 May 2023: 15 days between the first and last heat detection of the perimeter. According to CONAFOR, the largest of the 2 recorded fires was detected on 13 May 2023 and declared extinguished on 28 May 2023.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 9,486 hectares (94.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Amatlán de Cañas (8,787 ha, 17 %); Ixtlán del Río (753 ha, 1.5 %).
What was the weather like?
During the fire the temperature reached 30.9 °C, humidity dropped to 13 % and gusts hit 54 km/h. The fire danger index (FWI) reached 48, 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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 911.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 2 polygons grouped in this page.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 612 Suomi-NPP VIIRS detections on those dates.
  • Compared with CONAFOR: 8,018 official ha against 9,486 ha of perimeter; they agree within 25%.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • 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.
