BarcelonaTuesday's slight change in the weather has been more painful than wonderful. Scattered showers have fallen in some regions, leaving up to 6 l/m² in Sort (Pallars Sobirà) and 4 l/m² in the city of Tarragona. Not much. From Wednesday onwards, calm and sunny conditions will prevail across most of the country. But above all, we will notice a clear rise in maximum temperatures after the drop in recent hours. We're in for a few days of excessive heat and muggy conditions given the weather, with the highest highs approaching or reaching 35°C in the West and inland Ebro. It seems that from Sunday onwards, instability will increase, and next week we'll see a clear cooling off, coinciding with the official arrival of astronomical autumn.

Wednesday: hotter

During the early morning and early morning, there will still be low clouds in coastal and pre-coastal areas, especially in Barcelona and Tarragona, as well as in central Catalonia. Showers or drizzle are still possible along the southern coast. However, the sun will dominate the rest of the day, and will ultimately prevail in most regions.

A pleasant day to take advantage of, and above all, with significantly more warmth. Temperatures will rise sharply, with many highs ranging between 26 and 31°C, with more intense muggy conditions near the sea. Towards the west and inland south, these figures will be exceeded, with values between 32 and 34°C. Needless to say, these are above average for the season, so we'll sweat more than we should.

Summer heat has an expiration date

The weather will change little between Thursday and Saturday. It will remain calm, with more sun than clouds overall, and virtually no risk of precipitation anywhere. Temperatures will remain similar to Friday's, or at most increase by a few degrees. Intense, summery heat, atypical for our climate.

However, this warm weather is doomed, as the week will end with changes. The maps indicate that between Sunday and Monday, a pocket of cold air will arrive, clearly reactivating instability, with locally strong showers and thunderstorms in many regions. A still uncertain situation that we will have to confirm, but which will pave the way for a significant cooling off later on. The appearance of autumn is in sight, coinciding with the official arrival of the new season on Monday.
