How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2017.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Noisy-sur-École fire last?
- The official perimeter only gives the start date (12 July 2026). The end comes from the heat detections inside the perimeter: it burned until 14 July 2026 (3 days from 12 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 1,306 hectares (13.1 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 5 municipalities: Noisy-sur-École (757 ha, 25 %); Le Vaudoué (250 ha, 15 %); Fontainebleau (243 ha, 1.4 %); Achères-la-Forêt (55 ha, 4.4 %); Arbonne-la-Forêt (1 ha, 0.0 %).
- Did the fire reach a town?
- The fire started in Noisy-sur-École and came within 0.8 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 36.8 °C, humidity dropped to 18 % and gusts hit 46 km/h. The fire danger index (FWI) reached 62, class Extreme.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of France (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
- 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. 123 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 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 ADM5 (Open Data Commons Attribution License 1.0). 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.
