Patiño fire, 28 October 2026 Patiño

Burning · last detection 13 Nov 2026, 17:43 UTC

The fire started on 28 October 2026 in Patiño, Argentina, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,089 hectares from heat detections, spread across a single municipality.

Number 36 in Argentina in 2026, of 84.

GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

Is it still active?

Satellites detected fire on 13 Nov 2026, 17:43 UTC. Everything suggests it is still burning. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

The next 72 hours

The wind is blowing from the east and pushing westwards; no sharp shifts are expected until Mon 16, 18:00.

Sat 14, 06:00, local time

First useful rain: 2.2 mm in 6 h

Chance of rain up to 19 % in those hours. It can slow the fire at the surface, but that does not mean it will go out.

Checked, no warning: no wind shifts of more than 60° nights recover humidity (peaks of 73 % or more)

    This is not an official warning. It is a global model forecast with cells of about 25 km, at the centre of the fire: it cannot see valley winds or the winds the fire itself creates. The fan shows where the wind blows, not where the fire will spread. If in doubt, follow what the authorities say.

    Forecast: ECMWF IFS 0.25° (European Centre for Medium-Range Weather Forecasts), served by our own Open-Meteo instance; the chance of rain comes from the ECMWF ensemble. Variables: wind and gusts at 10 m, wind at 850 hPa, relative humidity and temperature at 2 m, rain. Open-Meteo.com (CC BY 4.0).

    How it is worked out: wind shift = a change of more than 60° in 6 h or less, with at least 15 km/h before and after; no overnight recovery = peak humidity between 8 pm and 8 am stays below 55 %; useful rain = 2 mm or more in 6 h. The fan opens 18° plus however much the wind varies within ±3 h and reaches 25 km beyond the edge of the fire: one model cell, not a rate of spread. Methodology

    It had gone 3 days without rain (1 mm or more) when it started.

    This area had burned before

    63% of the perimeter overlaps earlier fires recorded since 2016: 5 ha in 2017, 11 ha in 2019, 106 ha in 2020, 1,346 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,324 ha that had burned before.

    It burned the equivalent of 1.3% of the area of London (21 km² against 1,583 km²).

    Inside the perimeter there was no noticeable built-up land and almost nobody lived there (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.

    Frequently asked questions

    How long did the Patiño fire last?
    According to the heat detections seen by satellite inside the perimeter, it burned from 28 October 2026 to 13 November 2026 (17 days). The perimeter dates it from 4 November 2026 to 10 November 2026.
    How much area did it burn?
    The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,089 hectares (20.9 km²). It is an estimate: official national figures may differ.
    Which municipalities burned?
    The fire only entered Patiño (2,098 ha, 0.1 %).
    Is the Patiño fire still active?
    Yes: satellites detected fire on 13 Nov 2026, 17:43 UTC. Check the emergency service for the official status.
    What was the weather like?
    During the fire the temperature reached 39.2 °C, humidity dropped to 25 % and gusts hit 63 km/h. The fire danger index (FWI) reached 32, class High.
    What weather is expected at the fire over the next 72 hours?
    The wind is blowing from the east and pushing westwards; no sharp shifts are expected until Mon 16, 18:00. First useful rain: 2.2 mm in 6 h (Sat 14, 06:00). Times are local time at the fire. ECMWF IFS forecast (Open-Meteo) computed 13 Nov 2026, 21:53 UTC; this is not an official warning.
    Where does this data come from?
    From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Argentina (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: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
    • Dates adjusted with the VIIRS detections inside the perimeter, which said 4 November 2026 to 10 November 2026. 202 Suomi-NPP VIIRS detections on those dates.
    • We have not matched this page with any official record.
    • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
    • 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 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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
