It had gone 3 days without rain (1 mm or more) when it started.

This area had burned before

50% of the perimeter overlaps earlier fires recorded since 2016: 1,188 ha in 2016, 2,037 ha in 2022, 23 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 2,667 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 3.4% of the area of London (53 km² against 1,583 km²).

Frequently asked questions

How long did the Agios Vasileios fire last?
The official perimeter only gives the start date (29 July 2026). The end comes from the heat detections inside the perimeter: it burned until 30 July 2026 (2 days from 29 July 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 5,331 hectares (53.3 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Agios Vasileios (5,086 ha, 14 %).
What was the weather like?
During the fire the temperature reached 29.4 °C, humidity dropped to 48 % and gusts hit 78 km/h. The fire danger index (FWI) reached 32, class High.
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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 102 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Checked against news and agencies: 4 confirmed sources.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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.
