Firefighters and volunteers filmed a rare fire-tornado during a massive wildfire near Saumos in Gironde on Wednesday evening [1].
The phenomenon highlights the increasing volatility of wildfires under extreme weather conditions, posing a severe threat to emergency responders and local residents.
The blaze, which began July 22, 2026 [1], has ravaged the region near the Bassin d’Arcachon and Cap-Ferret. Reports on the total area burned vary, with estimates ranging from 2,000 hectares [2] to 2,400 hectares [3]. The intensity of the fire forced a large-scale evacuation of the area, with figures ranging from 8,800 [4] to approximately 12,000 people [2].
Witnesses captured footage of the fire-tornado, a rotating column of flame, at the heart of the blaze [5]. Experts said this rare and dangerous phenomenon can cause new outbreaks of flames, making the fire even more unpredictable [6]. The combination of high winds, intense heat, and dry vegetation created the specific atmospheric conditions necessary for the tornado to form [7].
Local authorities are struggling to contain the perimeter as the weather continues to hinder efforts. The prefect of Gironde said, "Les conditions sont défavorables" [4].
Civil protection volunteers and firefighters continue to monitor the situation near Saumos. The fire-tornado serves as a stark reminder of how extreme heat can transform a standard wildfire into a more complex meteorological event, complicating containment strategies and increasing the risk of rapid spread across the landscape.
“A rare “fire-tornado” was filmed at the heart of the gigantic fire ravaging Gironde.”
The emergence of a fire-tornado in Gironde indicates a dangerous feedback loop where intense heat creates its own localized weather systems. This increases the unpredictability of fire behavior, making traditional containment lines less effective and increasing the risk to personnel on the ground.
