Spain’s June 2026 Heatwave Triggers Over 1,000 Excess Deaths
7/2/2026, 6:33:54 AM
Record-Breaking Heat and Mortality Surge
In June 2026 a five-day heatwave pushed temperatures above 40 °C across much of Spain, making the month the second-hottest June on record after 2025. The Health Ministry’s MoMo system reported 1,028–1,029 excess deaths linked to heat, more than double the 407 deaths in June 2025. Euronews’ provisional count of 892 deaths reflects ongoing data updates.
Background & Context
AEMET noted average June temperatures 3.2 °C above the 1991-2020 norm and the first half of 2026 1.6 °C above normal. Since 1975 twelve June heatwaves have been recorded, half in the past decade. The agency highlighted that the 13 hottest Junes since 1961 all fall in the 21st century, signalling a clear warming trend.
Data & Statistics
Excess deaths ranged from 1,028 (Carlos III) to 1,029 (MoMo) and 892 (preliminary). At the peak, 35.7 million people—?73 % of the population—faced health risks, with 38 % classified as high-risk. AEMET recorded 165 maximum and 225 minimum temperature records broken, including 20 all-time highs and 45 all-time lows.
Official Statements & Responses
AEMET posted on X that the seven warmest first semesters have all occurred within the last ten years, emphasizing a decade-long shift toward hotter early seasons. The Health Ministry, via MoMo, said June 2026 recorded the highest heat-attributable mortality since the system’s 2015 baseline. Spokesperson Ruben del Campo warned that heatwaves now appear at summer’s start with greater frequency, urging heightened public-health alerts. AEMET also noted that the first half of 2026 was the warmest on record, with average temperatures 1.6 °C above normal.
Criticism & Scientific Attribution
The World Weather Attribution group asserted the June heatwave would have been “virtually impossible” without climate change, linking the event to a continent-wide pattern of record-breaking temperatures. This framing positions the mortality surge as a climate-driven health emergency. The attribution underscores that without anthropogenic warming, such extreme heat would be statistically improbable.
Conflicting Reports & Gaps
Death tallies differ: 1,028 (Carlos III), 1,029 (MoMo) and 892 (Euronews provisional). The discrepancy arises from distinct methodologies—direct heat-related death certification versus excess mortality modeling. Final figures for late June remain pending, leaving the precise total unresolved.

- “virtually impossible” in June without climate change. — World Weather Attribution group

- “Global warming is making summer not only hotter but deadlier for vulnerable populations,” — Ruben del Campo
What’s Next
AEMET forecasts continued above-average temperatures through the summer and warns of another potential heatwave. Authorities will keep heat-health alerts active, expand cooling-center networks, and accelerate climate-adaptation measures to protect elderly and medically vulnerable residents. The government is reviewing heat-wave contingency plans to improve shelter capacity and medical response.
