Wildfire Season Threat 2026: Experts Warn of 'Worst on Record' Risk as Spring Heat Arrives Early

Europe's leading wildfire scientists warn that the combination of unprecedented March heat, winter drought, and forest fuel accumulation creates extreme fire risk across the Mediterranean region.

Wildfire Season 2026: Scientists Issue Their Most Alarming Pre-Season Warning Yet

Europe's leading wildfire scientists and fire management authorities have issued their most alarming pre-season assessment in years, warning that the combination of an exceptionally dry winter across much of the Mediterranean region, the record-shattering March heat event that has prematurely dried vegetation, and the structural accumulation of combustible forest fuel following years of rural depopulation creates fire risk conditions that could produce a 2026 wildfire season to rival or exceed the worst in recent European history. The assessment, shared with the EU Copernicus Emergency Management Service and national civil protection authorities, uses multiple fire danger indices that are all simultaneously in their highest percentile ranges across significant portions of Spain, Portugal, France, Italy, and Greece.

The underlying drivers of extreme European wildfire risk are increasingly well understood by scientists, even if the political will to address them fully has been slower to develop. The combination of anthropogenic climate change — which is increasing temperatures, decreasing summer precipitation, and extending the atmospheric drought conditions that drive fire danger — and land use change — the abandonment of traditional fire-suppressing agricultural practices and the accumulation of biomass in unmanaged forests — creates a structural ratchet that pushes baseline fire risk progressively higher with each passing decade.

The early heat of March 2026 has specifically accelerated the timeline for fire risk in two ways. First, it has dried out winter moisture in vegetation and soil weeks ahead of the seasonal norm, effectively compressing the period before fire-prone conditions emerge. Second, it has promoted early plant growth — grass and undergrowth that will dry out and become ignitable fuel within weeks if the heat continues — creating a larger volume of fine fuels that are particularly important for driving rapidly spreading surface fires.
