Barcelona has set a new all-time heat record after temperatures reached 40.7C during the latest heatwave affecting much of Spain, according to Phys.org's report on the weather data. For residents, commuters and visitors, that means dangerous outdoor conditions in the city as temperatures move well beyond normal July levels.

Euronews reported that Barcelona registered 40.5C on Wednesday, describing it as the highest figure in 112 years of records. The same report said the thermometer also hit 37.7C overnight, leaving little relief after dark.

Record heat confirmed in Barcelona

The highest figure reported in the verified source material is 40.7C, cited by Phys.org on 9 July. That exceeds the 40.5C figure reported a day earlier by Euronews, indicating that the city's record was pushed even higher as the heatwave continued.

The source material does not provide a municipal notice from Ajuntament de Barcelona, Barcelona City Council, or a bulletin from Meteocat, Catalonia's weather service, setting out local restrictions or public instructions linked specifically to this record. The verified reports do, however, show that the city has entered exceptionally dangerous heat conditions.

Barcelona registered a maximum temperature of 40.5C on Wednesday, its highest figure in 112 years of records.

What the figures show

  • 40.7C, the top temperature reported by Phys.org on 9 July
  • 40.5C, the maximum temperature reported by Euronews
  • 37.7C, the overnight temperature reported by Euronews
  • 112 years of records, the period cited by Euronews for Barcelona's observed data

Those figures matter locally because overnight heat can be as serious as daytime peaks, especially for older residents, children, outdoor workers and people in homes without effective cooling. A night low of 37.7C means the city stayed extremely hot even after sunset.

What residents can do now

People in Barcelona should check updates from official local channels, including Ajuntament de Barcelona and Meteocat, for any heat alerts, public facility guidance or civil protection advice issued as conditions change. The verified source material supplied here does not include a direct official alert page link.

With temperatures above 40C reported in the city, the immediate practical risk is prolonged exposure outdoors, particularly in the hottest part of the day and in built-up neighbourhoods where heat lingers into the evening. The most recent confirmed figure in the supplied sources is 40.7C, reported on 9 July.
