Larissa fire, October 2026 Λάρισα · Larissa
Satellites first detected fire on 18 October 2026 in Larissa, Greece. It has been active for 7 days, with 12 heat detections and an area with fire of about 168 hectares rebuilt from them, spread across a single municipality.
The power measured by the satellite is low (8.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.
Compare with…
Copernicus has not yet published the burnt perimeter, which takes a few days to measure on satellite imagery. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.
Is it still active?
No detections since 24 Oct 2026, 11:49 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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 one day without rain (1 mm or more) when it started. Rain came after the fire: 19.9 mm on 25 Oct.
What happened to each town

168 ha reached on 18 Oct0.5 %
Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. 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.

Frequently asked questions
- How long did the Larissa fire last?
- According to the heat detections seen by satellite, it burned from 18 October 2026 to 24 October 2026 (7 days between the first and the last detection). There is no perimeter yet to date it.
- How much area did it burn?
- There is no official perimeter yet. Heat detections rebuild about 168 hectares with fire (1.7 km²); Copernicus will publish the measured figure within days.
- Which municipalities burned?
- The fire only entered Larissa (168 ha, 0.5 %).
- Is the Larissa fire still active?
- No fire detections since 24 Oct 2026, 11:49 UTC. A lack of detections is not an official extinction.
- Did the fire reach a town?
- The fire started in Larissa and came within 7.7 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 24.2 °C, humidity dropped to 40 % and gusts hit 20 km/h. The fire danger index (FWI) reached 5, class Very low.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Greece (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.
Report an error
How we know this
- No perimeter yet: the area (≈ 168 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
- Dates of the first and last VIIRS detection of the cluster. 12 Suomi-NPP VIIRS detections on those dates.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
Where this data comes from
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
