The weather in Spain at the beginning of September surprises even the most seasoned residents. Instead of the usual autumn coolness, much of the country is once again facing summer heat. Meteorologists report that in the southern regions, temperatures are confidently climbing above 38°C, and in some areas, they may even reach 40°C. It feels as if summer has decided to linger and will not give way to autumn.
While the northeast and the Mediterranean coast are experiencing unstable conditions with overnight downpours and cloudiness, the rest of the country is gradually sinking into a heatwave. The Catalan coast and the Balearic Islands are hit by heavy rain at night, and in Cantabria, the skies are overcast, but precipitation stops by midday. During the day, Catalonia, northern Castellón, and eastern Teruel can expect new waves of rain and thunderstorms, with isolated severe weather possible in the mountains and on the Balearics.
Despite these local bouts of instability, the overall trend is clear: temperatures continue to rise, especially along the Atlantic coast and in the Canary Islands. In the Guadalquivir valley, the heat has already surpassed 35°C, and nights in Mediterranean and southern areas remain truly tropical—the temperature does not drop below 20°C.
The forecasts for the coming days do not predict any changes. On Thursday and Friday, precipitation will persist only in the northeast and the Balearic Islands, while in Galicia and the northern Atlantic coast, only light rain is possible. On Saturday, brief showers are expected in the Pyrenees and along the Catalan coast, but by Sunday, the sun will completely take over. At the same time, heat will blanket the entire country.
According to meteorologists, the second week of September will be a turning point: an anticyclone will bring stable weather and even higher temperatures. In the Guadalquivir valley, highs above 38 degrees are expected, which is rare for this time of year. Rain, if it appears at all, will be limited to the far north, while the rest of the country will remain almost completely dry. The dry September is causing concern among residents in regions where water shortages have been felt since spring.
Long-term forecasts offer little optimism: from September 22 to 28, the heat will persist, and rainfall will remain minimal. The outlook for October is still unclear, though meteorologists do not rule out the possibility that the first week of the new month may also feel like summer. It will be especially hot in Andalusia, where temperatures in Córdoba and Sevilla may approach 39 degrees, as well as in the interior of Extremadura and southern Castilla-La Mancha. In other regions, the heat will be slightly milder but still above the normal values for September.
The only uncertainty remains on the Mediterranean coast, where unexpected bouts of instability are possible. Overall, however, Spain heads into autumn with a summer mood and record temperatures, while rain remains a rare visitor.
