Shush fire, May 2026 Shush
The fire started on 9 May 2026 in Shush, Iran, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 1,542 hectares from heat detections, spread across a single municipality.
It is the 9th largest in Khuzestan since 2016 (of 27 with a page). Number 4 in Iran in 2026, of 12.
The power measured by the satellite is low (28.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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 10 days without rain (1 mm or more) when it started.
This area had burned before
56% of the perimeter overlaps earlier fires recorded since 2016: 49 ha in 2020, 132 ha in 2021, 193 ha in 2022, 345 ha in 2023, 288 ha in 2024, 290 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 862 ha that had burned before.

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.
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 13 May 2026 the air beside the fire reached 190 µg/m³ of PM2.5. That day averaged 122: 8.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Shush fire last?
- GWIS (Copernicus) dates it between 9 May 2026 and 15 May 2026: 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 1,542 hectares (15.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Shush (1,542 ha, 0.4 %).
- What was the weather like?
- During the fire the temperature reached 44.0 °C, humidity dropped to 7 % and gusts hit 47 km/h. The fire danger index (FWI) reached 72, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Iran (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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 48 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
