The Spanish government and the State Meteorological Agency (AEMET) have placed eight autonomous communities under weather alert for an upcoming heat wave [1].
This extreme weather event poses significant public health and infrastructure risks as the country faces temperatures that could reach record levels. The frequency of these events underscores the growing impact of climate change on the Iberian Peninsula.
The heat wave is expected to begin on Sunday, July 7, 2026, and continue through the weekend into early next week [1, 2]. AEMET forecasts indicate that temperatures will exceed 40°C in parts of Spain, with a particularly strong impact expected in Galicia [1]. Some forecasts suggest maximum temperatures nationwide could reach up to 43°C [3].
Beyond daytime peaks, the agency warned of high overnight temperatures that prevent the environment from cooling. Rubén del Campo, an AEMET spokesperson, said there will be nights of up to 25°C [2].
According to AEMET, the current weather pattern is driven by a high-pressure system combined with broader climate-change trends [2, 4]. While some reports describe this as the first heat wave of the summer, other sources indicate it is the second major event in less than a month [1, 5].
Local authorities in the eight alerted communities are preparing emergency response measures to mitigate the effects of the extreme heat. Residents are encouraged to follow safety guidelines to avoid heatstroke, and dehydration as the system moves across the region.
“There will be nights of up to 25°C.”
The recurrence of high-temperature events in July 2026 suggests a volatile summer pattern for Southern Europe. By placing eight regions under alert, the Spanish government is acknowledging that extreme heat is no longer confined to the traditional southern plains but is affecting northern regions like Galicia, indicating a geographic expansion of climate risk.
