Sunday with fewer showers, but still with a lot of clouds

BarcelonaThe mercury has relaxed everywhere after a few days of intense heat and this Saturday it reached 36°C or 37°C where it climbed the most. Normal values for the season that make us think of a cooling down because we are coming from very high up. Storms were also the protagonists during the afternoon in many places, especially in the northern half and the center of the country, where they were locally accompanied by hail. Highlights include the 50 mm accumulated in Artés, in Bages, the 34 mm in Sant Pau de Segúries, in Ripollès, and the 33 mm in Gisclareny, in Berguedà. This situation will continue until the early hours of the night, when the last showers will fall, and on Sunday afternoon the instability will already be decreasing and less extensive and intense showers will form.

Sunday: less unsettled weather

The weather will remain unstable on the last day of the week, with a variable and changing sky overall. In the morning, the first showers will fall in the north of the country, and in the afternoon, the showers and thunderstorms will repeat, this time mainly in the northern half of the country, locally reaching even coastal stretches of the northeast.

All this with temperatures that could still drop a little more, both day and night, especially where it rained on Saturday afternoon. A more pleasant night atmosphere overall and cool in mountain areas, but still muggy near the sea. The highs will be mid-summer, but with much more moderate heat than in previous days, far from the 40 °C or 41 °C of Friday.

Monday: mercury rising

The week will begin with much calmer weather, with many more spells of sunshine practically everywhere. The exception will be found in parts of the coast, where there will be some intervals of low clouds during the morning. Elsewhere, very calm weather, although in the afternoon afternoon showers and thunderstorms will once again occur in the usual northern regions of the country. The temperature will rise, especially in Ponent, Empordà and the southern coast, while it could drop a little on the central coast and pre-coastal areas.

No great heatwaves in sight

Next week, thermometers will experience some ups and downs, even with intense heat in the middle of the week on a temporary basis. But no episode of extreme heat like in recent days is foreseen. In fact, at the end of next week, the temperature could drop more significantly and normalize completely, something that has not happened for almost the entire summer. This would translate into bearable heat during the day and mild or cool nights.

New heat records

This summer is being historic and exceptional in terms of heat and in Catalonia, records continue to be broken. In this regard, Friday was the eighteenth day on which somewhere in the country has reached 40°C this year, a new record for us of days in a year reaching this extreme figure, which beats the record registered last year. The record for tropical nights – above 25°C – has also been broken in the Raval neighborhood of Barcelona, a total of 48 as of Saturday this 2026, leaving behind the record of 45 tropical nights from 2022.

Furthermore, on Thursday, a new record for marine heat was registered in L'Estartit, in Baix Empordà. According to observer Josep Pascual, the sea surface temperature one mile from the Medes Islands has reached 27.77°C, an unprecedented record since Pascual began taking measurements in 1974 and which surpasses the current record from August 2024. An exceptional figure considering that it is the oldest series of sea water records in the Mediterranean. It is a value five degrees above the average.
