Overview
- Spain's meteorological agency Aemet called June 2026 'extraordinarily warm' and reported a mainland average temperature of 23.2°C, 3.2°C above the 1991–2020 norm.
- The heatwave that struck Spain on 22 and 23 June produced the hottest June days since at least 1950 and broke many records, especially in northern regions.
- Spain's MoMo mortality monitoring system gave a provisional estimate of about 892 excess deaths linked to the June heat, with more than 600 occurring during the most intense week.
- MoMo measures excess deaths by comparing observed deaths to expected baselines and does not assign direct causes, so the 892 figure is preliminary and may change as registrations are finalized.
- Aemet data show June heatwaves have become more frequent in recent decades, and experts say that rising temperatures driven by greenhouse-gas emissions raise short-term health risks and could further strain hospitals and care for vulnerable people.
