BarcelonaThe approaching Atlantic front will send some cold air aloft, causing temperatures to drop slightly on Monday. This will be a slight respite from highs that soared again this Sunday, for example, in the south of the country (at the end of this report, we've included a brief list of today's readings). During the afternoon, a few showers fell, accumulating 1 mm in Castelló d'Empúries and Roses.

The rest of the week will have normal temperatures for the time of year, or slightly below average. This means that the heat will be bearable, with a warm atmosphere, but no extremes or significant heat are expected.

The most significant development will be the arrival of new storms and showers on Wednesday, locally moderate to strong.

Monday morning weather forecast.

Monday: Tropical night on the coast and cooler weather inland

The forecasts indicate a drop in temperatures, but those living on the coast are incredulous because, once again, low temperatures have reached above 25°C (Meteocat has issued a nighttime heat warning for the coast). This drop in temperatures has been felt more inland, especially in the Pyrenees.

Nighttime heat advisory.

The drop in temperature will be noticeable in many coastal and pre-coastal areas, especially in the northern half, with highs that will no longer exceed 29°C. The highest temperatures will be in the West, inland Terres de l'Ebre, and in Central Catalonia, where they will reach 33°C or 34°C.

Showers are expected throughout the night in the northern third, and may be visible in the northeast until early morning. Elsewhere, low clouds will appear along the coast, while it will be calm inland, central Catalonia, the West Coast, and the Ebro. Showers may recur in the afternoon inland regions of Girona or south of Cape Begur.

A slight breeze from the north and the mistral winds will blow in early, bringing rough seas to the northern Costa Brava.

The temperature will rise on Tuesday, and storms will arrive on Wednesday.

The week will be changeable, with calm weather heading into Tuesday and a rise in temperature. On Wednesday, the entry of some cold air from above will cause storm clouds to form. Locally, they will be moderate to strong and will be accompanied by hail, strong gusts of wind, and, in some cases, hail. We will continue to monitor the situation!
