Temperatures will experience a sudden spike due to the warm southwesterly and westerly wind.

Today, temperatures have already exceeded 38 ºC near the Pre-Pyrenees and 39 ºC in Lleida, and the episode of intense heat and mugginess we are experiencing this week will experience a sudden peak this Wednesday. The strengthening of the heated wind from the southwest and west will suddenly shoot up temperatures in many regions, especially along the coast, pre-coastal areas, the Ebro region, and Central Catalonia. Extreme wind and heat that will increase the risk of fire and poor conditions in the forests. It will be a scorching day, with maximums reaching or exceeding 40 ºC in many parts of the pre-coastal areas, Central Catalonia, Lleida, and the Ebro valley, as well as 35 ºC on the coast. Meteocat has activated the alert for intense heat in a large part of the country, with a red alert – the highest possible – in the coastal area of Barcelona.

Temperatures will climb, especially inland, with a torrid peak on Wednesday.

The extreme heat has given a little respite this weekend, with very high values, but without the records of a few days ago. Throughout the week, temperatures will rise and the peak of the new episode of extreme heat will arrive, which will be even more intense than the previous ones. However, the presence of thin clouds or suspended dust can dampen the radiation and prevent the thermometer from soaring so much in the end. We are fully at the gates of what will be the third heatwave of the summer, when we will not have even recovered from the second one. Its peak will arrive between Wednesday and Friday. The stuffiness will make it impossible to rest on the coast, with torrid nights. In Ponent or Ebre, thermometers could reach or exceed 42°C maximum in the middle of the week.

Extreme heat has given a little respite this weekend, with very high values, but without the records of a few days ago. Yesterday, Saturday, many observatories in Ponent again brushed 38°C, with a lot of sultriness on the coast, due to low clouds. From today, temperatures will rise again and a new heat episode will begin. We are on the verge of what will be the third heatwave of the summer, when we will not yet have recovered from the second. The suffocating atmosphere gives no respite and after the sultriness we will again suffer a new influx of dry African air, with predicted values of up to 28°C at 1,500 m. This situation will cause thermometers to exceed 40°C again in many areas.

The second heatwave of the summer is just ending and the third is already showing its face. This Friday is the last official day of the episode that in recent days has shattered heat records across the country. Thermometers have begun to drop in recent hours, although they come from so high up that the atmosphere remains fully summery, with maximums that will still reach 40°C in Ponent. Meteocat maintains yellow alerts activated for intense heat in this area on Friday, as well as in Baix and Alt Penedès, Garraf, and Baix Llobregat.

Temperatures will drop until Saturday, but from Sunday the new extreme episode will begin.

Temperatures will drop between Friday and Saturday, but next week the heatwave will pick up again.

We wake up after a night of temperature contrasts. It has been warm and tropical in many regions, and scorching in parts of the coast and elevated areas of the pre-coast. The scorching night has even been repeated in Portbou (Alt Empordà), where temperatures have not dropped below 31 ºC all night. This location recorded the warmest night since records began in our region, specifically the night of Tuesday to Wednesday, with a minimum of 31.9 ºC. Also noteworthy are the minimums of 28.8 ºC at the Fabra observatory and 28.6 ºC in the Raval neighborhood of Barcelona. In contrast, these figures differ greatly from the coolness experienced in some areas, such as the valleys of the Pyrenees, where temperatures have dropped below 10 ºC.

The heatwave's peak continues to shatter records. The most notable is what was reached at the Fabra observatory in Barcelona, where temperatures exceeded 40 ºC and the absolute heat record, which had been in place since July 2024 at this location, was broken. Specifically, 40.8 ºC were provisionally reached at the Fabra station of the Royal Academy of Sciences and Arts of Barcelona (RACAB), and 40.5 ºC were confirmed at the Meteocat station. This is a figure that stands out particularly because in the more than 113 years of records at this observatory, such figures have never been reached.

Temperatures will exceed 40ºC in the hottest areas of the country, with sleepless nights.

The week has started with suffocating weather, and in some places yesterday was the hottest day of the summer so far, with values similar to those recorded on June 22nd, when the first heatwave occurred. We've had two heavier nights of sleep, especially on the coast, pre-coast, and in the south, with many tropical and some torrid minimums, especially in coastal stretches and in the north of Alt Empordà. Yesterday the maximums already made a significant leap forward and were around 40 ºC in many inland areas, especially in the south and Ponent. Notable were the almost 42 ºC maximum in Vinebre (Ribera d’Ebre) or the 41 in Lleida, and even on the pre-coast of Barcelona they approached 40 ºC, with up to 39.2 ºC in Vallirana (Baix Llobregat). A situation of persistent extreme heat that facilitated the generation of simultaneous fires. The meteorological conditions have improved during the night and have helped to advance favorably in the extinction tasks, with a drop in temperature and less wind.

The meteorological chronicle has, for weeks, been a simple collection of heat, sun, and more heat, with practically no new developments or notable changes. This weekend has not broken this monotony, with heat that has been intensifying and will do so even more during this new week. On Sunday, temperatures already approached 40 ºC inland, and this night has been tropical in many places, and torrid in coastal stretches, highlighting the 28.5 ºC minimum in Portbou (Alt Empordà) due to the reheated tramuntana wind, or the 27.6 ºC in the Raval neighborhood of Barcelona. The temperature will continue its relentless rise, which has multiplied the alerts for intense heat in many regions by Meteocat. The alerts extend throughout the country, and are red - the maximum possible danger - especially on Wednesday. The second heatwave of the summer is here, and it will be long and suffocating, as it will last for almost the entire week.

The heat intensified on Saturday, after a few days of respite with more controlled heat. It is the prelude to a new heatwave that will start this Sunday and push the mercury up to 42 or 43 °C in Ponent and the Ebro basin, with fully sweltering heat that will also reach the rest of the country. It will not be as intense a heatwave as the one we suffered in June, but we will once again be well above the meteorological average for early July. All this with a sun that will prevent any possible cloudiness or showers and with a risk of fire that remains high.
