Filadelfia fire, September 2026 Filadelfia, Bahía Negra

Out · last detection 27 Sept 2026, 18:02 UTC

The fire started on 24 September 2026 in Filadelfia, Paraguay, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,092 hectares from heat detections, spread across 2 municipalities.

It is the 132th largest in Boquerón since 2016 (of 291 with a page). Number 35 in Paraguay in 2026, of 79.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 2.0 mm on 29 Sept.

This area had burned before

76% of the perimeter overlaps earlier fires recorded since 2016: 1,328 ha in 2023, 1,957 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,591 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

The weather day by day

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 Filadelfia fire last?
GWIS (Copernicus) dates it between 24 September 2026 and 27 September 2026: 4 days between the first and last heat detection of the perimeter.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,092 hectares (20.9 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Filadelfia (1,420 ha, 0.1 %); Bahía Negra (676 ha, 0.0 %).
Is the Filadelfia fire still active?
No fire detections since 27 Sept 2026, 18:02 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 41.2 °C, humidity dropped to 24 % and gusts hit 54 km/h. The fire danger index (FWI) reached 34, class High.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Paraguay (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.

Satellite cross-check

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.

Where this data comes from

The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 (Creative Commons Attribution 4.0 (CC BY 4.0)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
