It had gone 16 days without rain (1 mm or more) when it started.

This area had burned before

28% of the perimeter overlaps earlier fires recorded since 2016: 146 ha in 2017, 27 ha in 2020, 87 ha in 2022, 67 ha in 2023, 2 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 298 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 0.7% of the area of London (11 km² against 1,583 km²).

People and buildings inside the perimeter

GHSL 2025
Built-up area1.1 ha
Residents≈ 90

Inside the perimeter there were about 1.1 hectares of built-up land and about 90 residents (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

CAMS · Copernicus

On 21 July 2026 the air beside the fire reached 37 µg/m³ of PM2.5. That day averaged 28: 1.9 times the WHO daily guideline (15).

Frequently asked questions

How long did the نفزة fire last?
The official perimeter only gives the start date (20 July 2026). The end comes from the heat detections inside the perimeter: it burned until 20 July 2026 (1 day from 20 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 1,062 hectares (10.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: نفزة (1,065 ha, 1.8 %); سجنان (0 ha, 0.0 %).
What was the weather like?
During the fire the temperature reached 42.3 °C, humidity dropped to 20 % and gusts hit 33 km/h. The fire danger index (FWI) reached 48, class Very high.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Tunisia (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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 198.

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. 66 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.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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 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 slightly from each country’s official figure.
