Hottest June in history recorded in Barcelona's city center

For the first time since records began, temperatures in Barcelona's city center did not drop below 20°C at any point during the entire month of June.

According to data analyzed by the Catalan News Agency (ACN) from the Catalan Meteorological Service (Meteocat), the Raval neighborhood experienced unprecedented heat this month, breaking all previous temperature records.

The streak began on the night of May 29, when temperatures first surpassed 20ºC. Since then, the temperature has remained above that threshold every night in June.

Raval endured a total of 32 consecutive tropical nights, which are defined as nights when the temperature does not fall below 20°C.

More concerning still, the last 11 nights of the month were classified as torrid, with temperatures never dropping below 25ºC.

The previous record for tropical nights in Raval in June was 26, set in 2022. This year shattered that record, with every night exceeding the tropical night threshold.

On the final night of June, yet another record was broken when the minimum temperature reached 27.6°C, the highest nighttime temperature ever recorded in the neighborhood.

Citywide records broken

Meanwhile, the Fabra Observatory, located in the Collserola mountain range, recorded the highest June temperature in Barcelona’s history.

On the afternoon of June 30, the observatory registered 37.6ºC, surpassing the previous June record of 37.3ºC set in 2019.

The station also recorded five days with temperatures above 35ºC, something that had only occurred once before in the past century.

Protecting the vulnerable

The Barcelona City Council activated a special emergency plan on Tuesday to protect vulnerable residents during the ongoing heatwave. 

Municipal teams were deployed in the Sant Martí and Sants districts to distribute bottled water, caps, and hand fans.

The initiative aims to provide immediate relief to those most at risk from extreme temperatures. 

Officials also shared information about the city’s 400+ climate shelters, air-conditioned public spaces where residents can seek refuge from the heat throughout the day.
