Barcelona set a new heat record on July 8, 2026, reaching 40.7 degrees Celsius, the highest temperature recorded in the city in more than a century, according to weather agencies. The previous record of 40.2°C was set in July 2015.
Record-Breaking Heat
The temperature was recorded at the official weather station in Barcelona's El Raval neighborhood. The extreme heat prompted the Catalan government to activate a heatwave alert, urging residents to stay hydrated and avoid outdoor activities during peak hours. The heat also affected the San Fermin festival in Pamplona, where revellers cooled off in fountains.
Impact on Health and Infrastructure
Health authorities reported a spike in heat-related emergency calls, with hospitals treating cases of heatstroke and dehydration. The city opened cooling centers and extended pool hours. Power grid operators warned of potential blackouts as air conditioning use surged.
According to meteorologists, the heatwave was caused by a high-pressure system over the Mediterranean combined with warm air from North Africa. Climate scientists attribute the increasing frequency of extreme heat events to global warming. 'This is consistent with climate change projections,' said Dr. Maria Lopez of the Barcelona Institute for Global Health. 'We expect more such records in the coming years.'
