Burning near Riachão, Brazil, a 300-hectare (741-acre) wildfire burned over the course of nine days following its start on August 15, 2026, averaging an expansion of approximately 33 hectares per day before finally ending.
Satellites detected a moderate heat intensity from the fire's peak radiative power, while four heat signatures were picked up nearby in the area over a 48-hour period, indicating the extent of the spread in the region.
This event unfolds during Brazil's typical fire season, which runs from August to October, though the wider national context shows that 3,683,458 hectares have burned so far in 2026, marking an 88% decrease compared to the two-decade average.
In context
This wildfire burned in Brazil for 2 days. In total it burned about 300 ha (741 acres) — around 3.0 km².
Close to the tropics, fires tend to follow the dry season and are often linked to land-clearing rather than a single summer peak.
The bigger picture in Brazil
Across Brazil, roughly 5,624,790 hectares have burned so far in 2026 — 82% below the two-decade average. Data from Copernicus GWIS.
