# Wildfires in Argentina in 2025

206 fires larger than 1,500 hectares in Argentina in 2025, with 647,890 hectares burned according to their perimeters. Here is the whole year: what the official record says, when and where it burned and what the weather was like.

## The year in a few sentences

- According to Copernicus GWIS, 2,628,875 hectares burned in Argentina in 2025: 62% of the average of the other years from 2012 to 2025 (4,211,665 ha). GWIS figures for 2025 and 2026 are provisional: they are left out of the average and the worst year. (Copernicus GWIS)
- The worst week was 29 January to 4 February: 136,704 hectares burned in seven days, 5% of the year according to Copernicus GWIS. (Copernicus GWIS)
- The largest fire was the Huiliches fire, which started on 30 January 2025 and burned 25,310 hectares: 4% of the area of the year's 206 fires with a page. (WorldFires)
- The day of highest danger at a fire this year was 26 December 2025: a Fire Weather Index of 103 (very extreme on the EFFIS scale) at the Gobernador Dupuy fire, calculated by WorldFires from ERA5. (WorldFires · ERA5)

Series not comparable from October 2025 onwards: GWIS changed its near-real-time perimeters.
