The weekend has been marked by fairly calm weather, with temperatures that have been dropping and which yesterday did not exceed 31 ºC in the warmest areas of Ponent and the Ebro valley. Values are still very high for this time of year, but nothing like the nearly 38 ºC of previous days. After so many days of anticyclones and atypically summery heat, this coming week promises to be much more unsettled and cooler, with rain that will end up making an appearance in practically every part of the country throughout the days, and thermometers that will continue to drop. It seems that autumn, now yes, wants to make itself truly felt.

The heat peaked this Friday with maximums of up to 37.4 ºC at the Riba-roja reservoir and 37 ºC in Vinebre (Ribera d'Ebre) and Aldover (Baix Ebre), but this weekend has started with less heat and the maximum values have remained around 32 or 33 ºC. This Saturday we already noticed an increase in thin clouds, a situation that will repeat on Sunday, when we will also have low coastal clouds. The coming week looks more unsettled and cooler, although still with a generally mild atmosphere.

The heat peaked this Friday with an atypical temperature spike that left values more typical of the height of summer than the first days of autumn, especially in the south and in Ponent. Unchecked heat that reached up to 37.4 ºC at the Riba-roja reservoir and 37 ºC in Vinebre (Ribera d'Ebre), or 37 ºC also in Aldover (Baix Ebre). Furthermore, 35 ºC was exceeded in areas of Ponent, and 34 ºC in parts of the northeast, the Priorat, and the Pre-Pyrenees of Lleida.

We are leaving behind a very stable weekend, with the sun in almost absolute control and temperatures that have risen progressively, both at dawn and during the central hours of the day, with controlled but more intense heat than in previous days. In fact, yesterday temperatures already brushed 35 °C in Ponent and inside the Ebro valley. A situation that will be repeated at the beginning of this week. Between today and tomorrow there will be a transient peak of heat, with maximums between 34 °C and 37 °C in the warmest areas of the interior. But all of this will be short-lived, as from Wednesday a new change in the weather will arrive that will bring more showers and a new clear drop in thermometers.

The weather remained very stable this Saturday, with some intervals of harmless clouds and a practically absolute dominance of the sun. The temperature rose even more, both at dawn and during the central hours of the day, with controlled but more intense heat than in previous days. In fact, it already brushed 33 °C in the West and in the interior of the Ebro valley, a situation that will be repeated this Sunday, which has begun with generally warm temperatures.

We have left behind a very peaceful and radiant National Day of Catalonia and we are entering a weekend that will continue to be marked by fresh mornings, mild midday temperatures, and sun, although with some nuances in the form of intervals of clouds. At the beginning of next week, we will have a transitory warm peak, but subsequently, we will experience a new drop in temperatures and a possible new episode of showers.

We are in for a very pleasant, radiant National Day of Catalonia to take advantage of, with very few nuances. Temperatures will remain normalized, with plenty of morning coolness and bearable heat kept in check during the middle of the day. Therefore, and as already happened this Thursday, 30 ºC will only be reached or slightly exceeded in parts of the south and in Ponent. The weekend will be similar, with small changes on Saturday, but quite calm and sunny in general. Thermometers will rise slowly, both by day and by night, but always far from extremes. At the beginning of next week we could have a transitory warm peak, which would not last long. We have set our path towards autumn, and, except for transitory peaks, there is no sign that would make us think of a return of extreme summer heat.

The announced change in weather is now here, which will mark the end of this episode of intense and atypical heat that has accompanied us during the first week of September, with temperature records. The passage of a cold front will complicate the meteorological situation and will make today an unstable day, with irregular downpours and storms that may be intense and leave some torrential deluges, with a risk of local flooding and sudden rising of rivers and streams. The area most affected will be the coast and pre-coast of Barcelona. The clash between cold air at high altitude and the intense heat accumulated over so many days can leave very significant downpours, which is why a large part of the country is on alert for intense rain. In fact, between the early morning and the first hours of the morning, heavy rain has affected the Garraf, the Baix Llobregat, the Penedès, and the north of the Vallès Occidental and Oriental, with a lot of electrical activity. Even so, the precipitation has moved quickly and has not left large accumulations for the moment. For example, more than 20 l/m² have already accumulated in a short time in Cunit, in the Baix Penedès.

The atypical and historic heat that has accompanied us at the beginning of this month is numbered, with weather that will already start to change on Tuesday and a temperature that will begin its descent in some points. It will be on Wednesday when we will notice the change in weather, with intense rain, wind, rough seas, and a lower temperature everywhere, with an environment more typical of the meteorological autumn.

The nightmare of this atypical and historic heat is numbered. This Monday we will no longer reach 40 °C in the Ponent area, although it will still be very hot. The drop in the thermometer will be slight, around 3 or 4 degrees in some places, enough so that no more records are set. However, it will still be hot, with highs around 38 or 39 °C in Ponent and in the interior of the Ebro. From this Sunday it is worth highlighting new exceptional values, not at all common in the month of September, such as 42.5 °C in Vinebre and 42.3 °C in Torroja del Priorat.

The temperature rose clearly yesterday Wednesday, when it exceeded 35 °C in many inland points and new heat records were registered in a month of September, as in the case of the Fabra Observatory, where the 33.6 °C measured is the highest value since 1914. All of this is the prelude to an exceptional heatwave that will cause the temperature to be well above the climatic average, with forecasts of registering new temperature records in the coming days.

The widespread feeling this summer has been one of unbearable and endless heat, which is even extending into this early September. The Meteorological Service of Catalonia published this Wednesday its seasonal report for the meteorological summer – which ends at the end of August – and certifies that, indeed, this year's has been the warmest since records began. The average temperature for the country as a whole registered a thermal anomaly greater than +3.0 °C with respect to the reference period 1991-2020 in over 80% of the territory, while some locations, such as the western Pyrenees or the plain of Vic, have reached +4.0 °C above normal values for the time of year. Meteocat highlights that the twenty historical data series in the country, those exceeding 75 years of data, have recorded the warmest summer in their series, “and this result shows that the temperature record does not correspond to the exceptional behavior of a specific sector, but rather has occurred in a generalized manner across the entire territory”.

Meteorological autumn began on Tuesday with very calm weather, dominated by the presence of clouds that, from midday onwards, gained ground, although they did not leave any precipitation. The mercury relaxed a bit, with maximums of 32 ℃ or 33 ℃ where it was hottest, but from this Wednesday onwards the situation will reverse and the temperature will rise notably. We are expecting a second half of the week with thermal values well above the climatic average for early September, with no significant cooling in sight.

Mercury again exceeded 35 ℃ this Monday, as it did over the weekend, but in general the temperature remained around 29 ℃ to 33 ℃. These are typical values for the end of August that will also accompany us into early September, with heat that could intensify more from mid-week. On the horizon there is no early autumn rain storm, but also no extreme off-season heatwave.

The mercury rose above 35 ℃ again this Sunday, after a fairly cool night everywhere, although less so than Saturday. The temperature will remain with few changes this week, with controlled heat, without excesses, and the weather will also not experience significant changes. On the horizon there is no early autumn storm, but neither is there any out-of-season heatwave.

Mercury once again exceeded 35℃ this Saturday, after a quite cool early morning everywhere, even on the coast, a situation that will be repeated this Sunday. The week will end with a very calm day with no new developments, marked by a temperature that will tend to rise progressively and by a sun that, although it has already lost many minutes compared to the end of June, is still the protagonist.

The mercury dropped much shorter this Friday, after a Thursday with highs of over 36 ℃ or 37 ℃ in Alt Empordà, El Segrià and in points of the pre-littoral, and it barely exceeded 32 ℃ or 33 ℃ where it was hottest. However, a weekend awaits us in which the temperature will recover and the sun will once again be the protagonist, with no risk of precipitation.

The mercury climbed eagerly this Thursday, with highs of over 36 or 37 ℃ in Alt Empordà, Segrià and points of the pre-coastal area, but this thermal rise has limited hours because in the coming hours we will experience a notable drop in temperature. Subsequently, however, it will gradually rise again, always around the climatic average and without extremes.

We have left behind a Wednesday of very calm and stable weather, with two very distinct faces: a very cloudy morning and an afternoon with a lot of sun. Thursday has started with a repeat of the play and some cloud intervals, but the sun will assert itself much more quickly and give way to a much more pleasant and warm day. We find ourselves immersed in a thermal roller coaster, as after this thermal rise there will be a drop in temperature on Friday, while the weekend will be warmer again.

This Tuesday's weather was radically different from Monday's, with a clear dominance of the sun, and this Wednesday the novelty will be the presence of clouds that will be abundant during the morning, but which will lose the battle against the sun during the afternoon. Nevertheless, only a few isolated and unimportant drizzles are expected.
