Formia fire, August 2026 Formia, Itri
The fire started on 12 August 2026 in Formia, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 141 hectares from satellite imagery, spread across 2 municipalities.
It is the 32th largest in Latina since 2016 (of 52 with a page). Number 155 in Italy in 2026, of 231.
The power measured by the satellite is low (1.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in
It had gone 15 days without rain (1 mm or more) when it started. Rain came after the fire: 2.1 mm on 17 Aug.
This area had burned before
94% of the perimeter overlaps earlier fires recorded since 2016: 103 ha in 2017, 10 ha in 2020, 10 ha in 2021, 112 ha in 2022, 8 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 133 ha that had burned before.

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 Formia fire last?
- The official perimeter only gives the start date (12 August 2026). The end comes from the heat detections inside the perimeter: it burned until 12 August 2026 (1 day from 12 August 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 141 hectares (1.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Formia (141 ha, 1.9 %); Itri (0 ha, 0.0 %).
- Did the fire reach a town?
- The fire started in Formia and came within 2.2 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 32.5 °C, humidity dropped to 47 % and gusts hit 22 km/h. The fire danger index (FWI) reached 19, class Moderate.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Italy (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. One Suomi-NPP VIIRS detection 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 ADM4 (Creative Commons Attribution 3.0 License). 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.
