After a stifling period of heat, the weather in Spain has experienced a sharp change this weekend. According to the State Meteorological Agency (AEMET), this Sunday temperatures will exceed 30 degrees only in specific areas of Andalusia and the Mediterranean. In contrast, most of the country will experience milder temperatures, between 20 and 30 degrees, and even cooler in mountainous areas and northern Spain.

However, the drop in temperatures has its own price: Catalonia and the Balearic Islands are facing greater atmospheric instability. J. J. González Alemán, AEMET physicist and meteorologist, has not hesitated to warn about this abrupt climate change through social networks. “We have an atmosphere with great convective potential, with probable extremely adverse storms in Catalonia,” he tweeted.

This omen materialized this Saturday, August 26, when a heavy rain, accompanied by hail, unloaded on Catalan lands. Although the damage has been relatively minor—small floods, landslides, and falling branches—instability has left its mark on Catalonia.

For this Sunday, August 27, the AEMET has activated the orange warning for stormy showers in the Balearic Islands, the Valencian Community and Catalonia. It is expected that the morning will be wet in these regions, even with hail, while in the afternoon only the Balearic Islands will be affected. Temperatures will drop drastically throughout Spain.

However, this climate volatility appears to be a passing phenomenon. AEMET anticipates a stabilization of the climate from Monday. Temperatures will begin to gradually recover, although they will remain below what would normally be expected for this time of year during the first days of the week.
