Spain reported a record number of heat-related deaths during May, health officials confirmed on Wednesday. Authorities linked 101 deaths to extreme temperatures across the country. This figure marks the highest May total since records began in 2015.
The Health Ministry stated that the death toll exceeded the decade-long average significantly. Officials reported that the figure was 3.6 times higher than previous May averages. Moreover, the ministry highlighted the growing health risks from early-season heatwaves. It stressed that dangerous temperatures arrived before the official start of summer.
Temperatures Reach Unusual Levels Across Spain
Several Spanish cities recorded new temperature highs during late May. According to meteorological officials, northern regions experienced especially unusual heat. The national weather agency, Aemet, described the temperatures as extraordinarily high for May.
Furthermore, weather experts observed record-breaking conditions in multiple locations. These extreme temperatures increased health concerns nationwide. Authorities urged residents to take precautions during hot weather conditions. They also warned vulnerable groups about heat-related health risks.
Climate Change Intensifies Extreme Weather Events
Government data showed that heat caused 27,564 deaths between 2015 and summer 2025. The ministry attributed these deaths directly to high temperatures. Meanwhile, 2022 remained the deadliest year on record. Officials linked 4,789 deaths to extreme heat during that year.
In comparison, 2025 recorded 3,832 heat-related deaths across Spain. The country also experienced its hottest summer ever recorded. Aemet reported an average summer temperature of 24.2 degrees Celsius.
Meanwhile, several European countries recorded their hottest May days this year. Scientists continue linking these events to human-driven climate change. They say climate change increases the frequency and intensity of heatwaves, droughts, and floods worldwide.
