Spain reported at least 1,028 heat-related deaths during the heatwave, a figure more than double the recorded fatalities for the same period in 2025. According to the Carlos III Health Institute, this surge coincides with the hottest six-month start to a year in Spanish history, as extreme heatwaves continue to impact the European continent.
Why is 2026 recording higher heat-related mortality?
The spike in mortality rates is linked to record-breaking temperatures that have persisted across the region. Spain’s national weather agency, Aemet, confirmed that the average temperature for the first six months of 2026 was 1.6 degrees Celsius above normal. Data from the Carlos III Health Institute shows that the death toll of 1,028 is a significant increase from the 407 heat-related deaths recorded in June 2025.
Aemet reports that seven of the hottest six-month periods have occurred within the last 10 years, highlighting a clear trend of rising baseline temperatures.
How does 2026 compare to previous heat records?
The intensity of the 2026 heatwave is significant. Aemet data indicates that June 2026 was the second-hottest June on record, with average temperatures reaching 3.2 degrees Celsius above normal. June 2025 currently holds the record as the hottest June in Spain.
| Period | Heat-Related Deaths |
|---|---|
| June 2025 | 407 |
| Heatwave 2026 | 1,028 |
What is the broader impact across Europe?
The extreme weather is not confined to Spain. According to the group World Weather Attribution, the heatwaves affecting Europe since late June are the most severe ever recorded in the region. Scientists associated with the group stated that these events would be “almost impossible” without the influence of climate change.
Record temperatures have been shattered across several nations:
- Germany, Poland, Czech Republic, Slovakia, and Hungary: All-time temperature records were broken.
- United Kingdom and Switzerland: New records for the hottest temperatures in June were established.
- France: The country recorded new highs for average regional temperatures and its warmest nights on record.
