The Guadalquivir Valley has once again lived up to its reputation as Spain’s furnace, registering the highest temperatures in the country this summer.
According to Spain’s national weather service AEMET, Jerez (Cadiz) scorched to 45.8C and Moron de la Frontera (Sevilla) hit 45.2C on August 17.
The readings came at the peak of a brutal heatwave that sealed August 2025 as one of the hottest months in Spanish history, on par with August 2024.
The report from AEMET confirms that August was ‘extremely hot’ across the country, with national average temperatures sitting two degrees above normal.
In some regions, thermometers soared six degrees higher than the seasonal average, making this heatwave among the most intense on record.
While Jerez and Moron bore the brunt, extreme conditions were also logged in central Andalucia, the interior of Galicia, the Cantabrian mountains, both plateaus, northern and central Extremadura and parts of Valencia.
Murcia saw the country’s third-highest reading of the summer – 45.1C – on July 18.
August 17 was particularly punishing: six Andalucian weather stations recorded above 45C, and 239 stations nationwide registered 40C or more.
Despite the heat, rainfall was scarce. With an average of 14.4 mm, August was classed as ‘dry’, representing just 66% of the month’s usual rainfall.
It ranks as the 16th driest August since records began in 1961. The Canary Islands, by contrast, experienced their fifth-wettest August in over six decades.
AEMET’s findings underscore growing concerns about Andalucia’s vulnerability to climate extremes, with the Guadalquivir Valley repeatedly emerging as the epicentre of Spain’s record-breaking heat.
