Wildfires in the United States

Situation over the last 30 days

319 fires detected in the United States over the last 30 days, totalling 28,995 hectares of cumulative footprint. The latest satellite detection (NASA FIRMS) dates from September 6 at 08:14 PM.

The fire season in the United States stretches from spring to autumn, peaking in summer in the West, with brush and forest fires fanned by hot downslope winds. Large fires arise within hours when drought and wind combine.

Other countries

These figures come from satellite thermal detection and are not an official tally: only the emergency services of the country concerned are authoritative. The detected footprint overstates the area actually burnt, a 375 m pixel counting whole when only an edge burns. A freshly detected fire may not yet carry a place name and will then not appear in this list, though it is already on the map.
