Intense Heat Wave Sweeps Through Spain in August 2025

Spain is experiencing its second significant heat wave of the summer, initiated on August 3, 2025, which is projected to endure until at least August 7. According to the Spanish meteorological agency (AEMET), regions such as the Guadiana and Guadalquivir valleys are bracing for extreme temperatures that may peak at 45ºC.

The heat wave is anticipated to reach its climax on August 5, with major cities including Madrid, Córdoba, and Badajoz expected to see temperatures exceed 40ºC. Central and southern Spain is also plotting nighttime lows that will not dip below 23-25ºC, heralding a series of tropical nights characterized by warm temperatures that hinder restful sleep.

Beyond the immediate forecast, there are concerns that this heat wave may extend well beyond its expected end date of August 7, with predictions indicating that many parts of the country, particularly in the northern areas, could continue to experience elevated temperatures throughout the following week. The upcoming weekend before the wave officially began had already set the stage with temperatures cresting near 40ºC in cities like Córdoba and Sevilla.

Meteorologist projections indicate that while the heat intensity may vary slightly from region to region, areas in Galicia, Castilla y León, Aragón, and Catalonia will likely face heightened temperatures as well. The current heat wave has been classified as severe and has the potential to affect public health and well-being, exacerbating challenges related to sleep and daily activities for the affected populations.

This summer's extreme weather conditions underline a growing trend and concern regarding the frequency and severity of heat waves impacting Spain, raising questions about public preparedness and climate resilience in the face of ongoing weather changes.
