Derbyshire fire, July 2026 Derbyshire, Tameside, Oldham

Out · last detection 25 Jul 2026, 11:38 UTC

The fire started on 12 July 2026 in Derbyshire, United Kingdom, and satellites saw it burning for 14 days. Copernicus mapped a burnt perimeter of 660 hectares from satellite imagery, spread across 3 municipalities.

It is the 5th largest in England since 2016 (of 29 with a page). Number 9 in United Kingdom in 2026, of 21.

The power measured by the satellite is low (5.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Frequently asked questions

How long did the Derbyshire 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 25 July 2026 (14 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 660 hectares (6.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Derbyshire (608 ha, 0.2 %); Tameside (55 ha, 0.5 %); Oldham (1 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 25.4 °C, humidity dropped to 36 % and gusts hit 24 km/h. The fire danger index (FWI) reached 15, class Moderate.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of United Kingdom (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. 7 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 ADM3 (Open Government Licence v3.0). 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.
