The last week of August brought hail, torrential rain, and winds up to 140 km/h. Catalonia and the Balearic Islands suffered material damage and emergency alerts. Authorities responded to dozens of incidents.
Unpredictable weather has disrupted the end of August in Spain, with Catalonia and the Balearic Islands facing a series of violent storms. Hail, torrential rain, and wind gusts reaching 140 km/h have caused significant material damage, especially in Tarragona, where emergency services were called to more than 140 incidents. Fallen trees, minor flooding, and destroyed vehicles and street furniture have been reported, with images from Tarragona circulating widely on social media.
According to Antena 3, the sudden shift from summer heat to autumn-like conditions was triggered by an Atlantic storm system crossing the peninsula and combining with cold air. The result was a dramatic drop in temperatures, with some areas recording up to 10 degrees less within 24 hours. Most of the emergency calls in Catalonia came from Tarragona, where firefighters responded to flooding and wind damage, particularly from fallen branches and trees.
As the storm system moves east, meteorologists expect the worst of the rain and storms to subside. However, strong showers may still affect northeast Galicia and Asturias, especially in the afternoon. Elsewhere in Spain, clearer skies and cooler mornings are forecast, but this relief will be brief. Temperatures are expected to rise again from Tuesday, with regions like Cantabria and the Basque Country likely to see another day of southern winds by midweek.
The Balearic Islands have also experienced rare weather phenomena. In Mallorca, several 'rissagas' or meteotsunamis were recorded in Alcúdia, Andratx, Sóller, and Port Adriano. In Port d'Alcúdia, a sudden surge of water reached seaside terraces, surprising pedestrians and customers. Menorca remained under alert for sea level oscillations, and material damage accumulated in just a few hours.

Looking ahead, forecasts indicate that by the weekend, temperatures will return to more typical summer values across much of Spain. The recent sequence of storms highlights the volatility of late summer weather, especially when Atlantic systems interact with local conditions. Such episodes can disrupt daily life, damage infrastructure, and require rapid response from emergency services. In Spain, late August and early September are often marked by sudden weather changes, with the risk of heavy rainfall and localized flooding increasing as the season transitions toward autumn. Residents in affected regions are advised to stay alert to official warnings and prepare for further shifts in weather patterns as the month ends.
