Scorching Barcelona Shatters Heat Record: City Gripped by Historic 40.5C Temperatures

Barcelona registered a historic maximum temperature of 40.5C on Wednesday, marking its highest figure in 112 years of records as Spain grappled with another intense heatwave. This provisional reading, taken at the Fabra Observatory on Barcelona's western outskirts, surpassed the city's previous record of 40C, which was set recently on July 30, 2024, according to regional weather monitor Meteocat.

Even at Barcelona's El Prat airport, located almost at sea level and adjacent to the Mediterranean, the thermometer climbed to 37.7C. This specific measurement represents the highest reading in records for that location, extending back to 1924, as confirmed by the national weather agency AEMET. AEMET spokesman José Ángel Núñez emphasized that these two stations serve as the city's primary observatories of reference, unequivocally stating, "Barcelona has recorded the hottest day."

The proximity of the Mediterranean Sea typically provides a moderating effect on temperatures in Spain's second-largest city, which is also a major global tourist destination. However, this protective influence was overwhelmed by the current heatwave, which commenced in Spain on Sunday and is projected to persist until Thursday. Throughout the country, some weather stations have reported temperatures exceeding 44C this week.

In response to the severe conditions, AEMET escalated its warnings, issuing the highest red alert for heat in specific areas of the Catalonia and Valencia regions on Wednesday. Furthermore, the second-highest orange alert was in effect for extensive swathes of central, southern, and northeastern Spain, encompassing Barcelona. This event follows an exceptional heatwave that gripped much of Europe in late June, during which mainland Spain endured its highest daily average temperatures for the month since at least 1950, reaching 28.17C.

The human toll of such extreme weather events is significant. Estimates from the MoMo monitoring system indicate that more than 1,000 deaths could be linked to heat in Spain during the previous month alone. Scientists consistently highlight that human-driven climate change is a critical factor in the increasing intensity, prolonged duration, and heightened frequency of extreme weather phenomena, including heatwaves like the one currently affecting Spain.
