Spain is bracing for another surge of extreme weather as the Agencia Estatal de Meteorología (AEMET) warns of soaring temperatures and unstable conditions across much of the country. Wednesday’s forecast calls for intense heat and clear skies, with sudden storms also possible. Inland and southern regions are expected to face the most severe impacts. AEMET’s national Meteoalerta system provides adverse-weather forecasts and warnings for up to 72 hours, with regional updates as hazardous conditions develop.
Madrid will see temperatures climb to 40°C, with intervals of cloud and Saharan dust, known locally as calima. Winds will remain light before shifting to the southwest later in the day. In Andalusia, maximum temperatures could reach 43°C, with storms and hail also possible in the eastern sierras. Fog banks are likely along the coast, and westerly winds will strengthen as the afternoon progresses. AEMET’s warning structure covers hazards including extreme heat and thunderstorms, as well as hail, strong winds and reduced visibility from suspended dust.
Catalonia will see a mix of cloud and suspended dust, along with a impressive temperature drop in most areas, although highs could still reach 39°C. The south of Tarragona is at risk of afternoon storms, while coastal winds will ease by evening. Aragón will have partly cloudy skies and calima, with temperatures peaking at 41°C. The Ibérica zaragozana may see a slight rise in temperatures, while the Ebro depression could cool slightly. Winds will be light to moderate, shifting between southeast and southwest depending on the area.
Asturias will remain relatively stable, with clear or lightly clouded skies and the possibility of mist in the mountains. Temperatures will range from 15°C to 29°C, with a slight increase on the southern slopes of the Cordillera. Winds are expected to be light and variable inland, and easterly to northeasterly along the coast. AEMET publishes regional warning information through its territorial meteorological services, allowing conditions to be monitored in individual autonomous communities.
The Balearic and Canary Islands will have mostly clear skies, with some mid- and high-level clouds. Morning haze may accompany calima. Daytime temperatures will range from 22°C to 35°C, with tropical or even torrid nights in some areas. In the Canaries, Lanzarote and Fuerteventura may see more cloud cover, while Gran Canaria and Fuerteventura could reach highs of 30°C. Strong northeasterly winds are forecast in some areas overnight.
Galicia and the Comunidad Valenciana will see a mix of high and low clouds, with a chance of afternoon storms and showers. Temperatures are expected to range from 21°C to 38°C. Castilla y León and Castilla-La Mancha will also have mostly clear skies, with some mid- and high-level clouds. Minimum temperatures will rise slightly in the south, while maximums could reach 42°C in some areas. Albacete and eastern Cuenca are at risk of strong storms and hail, with calima reducing visibility. Winds will be light and variable, strengthening during storms.
Ceuta and Melilla will have mostly clear skies, with high clouds in the morning and suspended dust. Westerly winds will ease by afternoon, and temperatures will remain steady, with highs of 38°C in Ceuta and 34°C in Melilla. Clear skies will prevail in the Basque Country, Navarra and La Rioja, where temperatures will range from 14°C to 39°C. Winds will be light from the north inland and from the northeast along the coast.
These conditions follow a pattern of extreme weather that has become increasingly common in recent years. Heatwaves and calima, along with sudden storms, have already prompted authorities to issue multiple alerts this summer. Similar weather events have previously brought severe storms and hail to southeast Spain, as detailed in recent coverage of weather warnings for Valencia and Murcia.
Spain’s diverse geography means weather impacts can vary sharply from region to region. The south and interior face the highest temperatures and storm risks, while coastal and northern areas may see milder conditions but remain vulnerable to sudden changes. Suspended Saharan dust can reduce visibility and affect air quality, particularly in the east and islands, while storms can bring hail and abrupt local changes in wind. AEMET’s Meteoalerta structure provides detailed, continuously updated information on adverse weather and tracks its evolution as conditions develop. AEMET continues to monitor the situation and urges residents to stay informed and take precautions during periods of extreme heat and potential storms. These weather patterns affect health and infrastructure, as well as daily life across the country.
