Satellites are picking up a moderate heat signature from an active wildfire burning near União do Sul, Brazil, where 23 thermal detections over the past 48 hours trace the local spread of the front. Having started on September 29, 2026, the blaze has consumed 400 hectares, equivalent to 988 acres.

This incident unfolds during the region's typical fire season, which runs from August to October.

In context

This wildfire burned in Brazil for 2 days. In total it burned about 400 ha (988 acres) — around 4.0 km². That size is an estimate from satellite hotspots, not a measured area.

Close to the tropics, fires tend to follow the dry season and are often linked to land-clearing rather than a single summer peak.
