• The country experienced its hottest first half of the year on record.
• June 2026 was the second-hottest June, averaging 3.2°C above normal.
• The heatwave was linked to extreme climate change effects across Europe.
• Health risks affected about 73% of Spain's population during the peak of the heatwave.

In June 2026, Spain reported at least 1,028 heat-related deaths, marking a significant increase from the 407 deaths documented in June 2025, which was previously the hottest June on record. The public Carlos III Health Institute noted that this year's heatwave coincided with the hottest first semester since records began, with average temperatures 1.6°C above normal, according to The Local, India Times, and South China Morning Post.

According to the national weather agency Aemet, June 2026 saw average temperatures that were 3.2°C above the normal, making it the second-hottest June on record—only surpassed by June 2025. The severe heatwave impacted roughly 73% of the country's population, exposing 35.7 million people to health risks at its peak, with many facing high-risk conditions, as reported by India Times, South China Morning Post, and The Local.

The extreme heat was classified as the most intense heatwave ever recorded in Europe, with analysis from the World Weather Attribution group of scientists stating that such an event would be "virtually impossible" without climate change. All-time temperature records were broken in several countries, including Germany and Poland, highlighting a broader trend of rising temperatures across Europe, according to South China Morning Post, India Times, and The Local.

This June marked the beginning of yet another wave of heat impacting various regions across Europe, differing from previous patterns where high temperatures occurred later in the summer. Such ongoing events signify a concerning trend driven by climate change, as noted by meteorological agencies, and demonstrate the increasing frequency and intensity of summer heatwaves, as stated by South China Morning Post, India Times, and The Local.
