BRUSSELS — Europe is facing its deadliest heatwave season on record, with between 1,300 and more than 10,440 heat‑ and fire‑related deaths reported so far in 2026, according to health agencies and climate‑impact assessments.

The World Health Organization (WHO) confirms more than 1,300 excess deaths across Europe since 21 June, based on national mortality data from multiple member states. These figures represent excess mortality during periods of extreme heat and are widely used as the standard indicator for heat‑related fatalities.
A broader climate‑impact analysis, covering late May through July, reports over 10,440 deaths linked to the 2026 heatwave season. This higher estimate includes medically confirmed heat deaths, indirect fatalities caused by infrastructure failures, wildfire impacts, and excess mortality across 13 European countries. Researchers say it is the highest heatwave death toll ever recorded on the continent.
Wildfire‑related deaths, which are not included in WHO’s heatwave mortality figures, continue to rise. Verified national reports include three firefighters killed in Greece during July wildfires in Crete and the Peloponnese. Additional civilian and responder deaths have been reported in Spain, France, Italy, and Turkey, though a consolidated Europe‑wide total has not yet been published.
Emergency services across Europe warn that prolonged heat, drought, and expanding fire fronts are likely to continue driving mortality through August, with several countries maintaining red‑level heat alerts and large‑scale wildfire response operations.
How 2026 compares to last year’s statistics
Overall finding
Europe’s 2026 heatwave season is significantly deadlier than 2025 — in every available metric.
Even the lowest 2026 estimate (WHO’s 1,300+ excess deaths) exceeds the highest confirmed national totals from 2025.
The full-season estimate (10,440+) is more than double last year’s broad mortality count.
2026 vs 2025 — side‑by‑side comparison
🔥 Confirmed heat‑related deaths
- 2026:
1,300+ confirmed excess deaths (WHO, 21 June–1 August)
- 2025:
Most countries reported 100–400 confirmed heat deaths each.
Europe‑wide confirmed total: ~1,000–1,200
(based on national health ministry reports from France, Spain, Italy, Germany, and Greece)
➡️ 2026 already exceeds 2025’s confirmed total, and the season is not over.
---
🌡️ Full heatwave mortality (excess + indirect deaths)
- 2026:
10,440+ deaths (late May–10 July)
Includes medical heat deaths, indirect deaths, infrastructure failures, wildfire impacts, and excess mortality across 13 countries.
- 2025:
Europe recorded 4,800–5,200 heatwave‑related deaths (May–August).
This includes excess mortality and indirect deaths during the 2025 Iberian, French, and Balkan heatwaves.
➡️ 2026 mortality is more than double 2025, making it the deadliest heatwave season ever recorded in Europe.
---
🔥 Wildfire‑related deaths
- 2026:
- 3 firefighters killed in Greece (Crete + Peloponnese)
- Additional civilian and responder deaths reported in Spain, France, Italy, Turkey
- No consolidated Europe‑wide total yet
- 2025:
- 2 firefighters killed in Greece
- 1 civilian death in Spain
- Several injuries and evacuations across Italy and France
- Total: ~3–4 confirmed wildfire deaths
➡️ 2026 wildfire mortality is already higher, with more active fires underway.
Summary
Europe’s 2026 heatwave season is substantially worse than 2025:
- Higher confirmed deaths
- Far higher excess mortality
- More wildfire‑related fatalities
- More countries affected simultaneously
- More severe infrastructure impacts (power grids, water shortages, transport failures)
2026 is now reportedly the deadliest heatwave year ever recorded in Europe, surpassing 2003 and 2022.
