Last update: July 22, 2025
  • A new heat wave is expected to hit Spain after a brief respite.
  • The alerts affect numerous regions, particularly the southeast of the peninsula and several major capital cities.
  • Authorities recommend taking extreme precautions and protecting the most vulnerable groups.
  • The evolution of the heat wave is linked to climate change, and uncertainty remains about the duration and intensity of the episode.

Next heat wave in Spain

The imminent arrival of a new heat wave High temperatures are once again at the center of the Spanish weather news. After several days of somewhat milder temperatures, the forecast indicates that extreme heat will return with intensity, affecting much of the country and generating concern among both the population and health and safety authorities.

Although the recent drop in temperature has brought slight relief to many provinces, experts' forecasts leave no room for doubt: summer is far from giving a definitive respite, and in the coming days, temperature peaks are expected that could set records in some parts of the country.

When will the next heat wave arrive and how will it be defined?

Heat wave weather forecasts

According to the State Meteorological Agency (AEMET), to officially call a heat wave, a period of at least three consecutive days with maximum and minimum temperatures above normal values is required in a significant part of the national geography. Currently, the main meteorological models and experts such as Jorge Rey and Rubén del Campo agree that the final stretch of July and the beginning of August concentrates the most evident risk of a new thermal increase, just after the slight decrease recorded recently.

This phenomenon This is no surprise in the Spanish summer calendar, where after a few days of relative relief, the heat usually returns, sometimes driven by influxes of Saharan air or anticyclonic ridges that maintain the stifling atmosphere. On several previous occasions, areas such as Andalusia, the Valencian Community, Castilla-La Mancha, and Murcia have reported highs exceeding 40 degrees and even tropical nights where temperatures never drop below 25°C, making it difficult to rest.

Provinces and areas on alert: updated information

Map of provinces affected by the heat wave

AEMET has activated orange and yellow warnings In several provinces, especially Murcia, Alicante, Valencia, and the Community of Madrid, temperatures are expected to reach or exceed 40°C in their capital cities. The heat will also hit hard in other cities such as Seville, Córdoba, Zaragoza, Lleida, Toledo, and Granada, where high temperatures are expected for several days.

During the nightsLarge areas of the Mediterranean and the southern Iberian Peninsula will experience lows that will not fall below 22-24°C, increasing the feeling of mugginess. On the Levantine coast, the Balearic Islands, and the Costa del Sol, so-called "tropical nights" and even torrid nights in some coastal areas will not be ruled out, a health risk factor to be taken into account.

In the specific case of Alicante Temperatures are expected to reach 38°C in the capital over the weekend, according to a forecast from the University of Alicante's Climatology Laboratory. The province will also experience a temperature fluctuation next week, with moderate drops followed by a possible new increase coinciding with the arrival of another warm air mass.

Recommendations and preventive measures for the heat wave

Tips for coping with a heat wave

Health and Civil Protection insist on the importance to maintain a constant hydrationAvoid direct sun exposure during peak hours and protect yourself with light-colored, lightweight clothing, hats, and sunscreen. Elderly people, children, and those with chronic illnesses should take extra precautions, as should those who work outdoors. In cities like Alicante, social resources have been strengthened, opening shelters and distributing hydration kits for vulnerable people.

We also remind everyone of the need to remain vigilant against heat exhaustion and other problems associated with peak temperatures. Citizen collaboration, such as providing shade and water to those who may need it, is a fundamental gesture in these situations.

The global context and the evolution of extreme heat

The phenomenon of heat waves This is not unique to Spain. Several European countries, including Italy, Greece, Cyprus, Romania, and several Balkan regions, are experiencing similar situations, with temperatures in some cases exceeding 45°C, forcing the implementation of special measures such as red alerts, work-hour restrictions, and the reinforcement of emergency services.

Meteorologists insist on not letting their guard down. and continue to monitor official announcements, as the intensity and duration of each heat wave can vary depending on the evolution of atmospheric systems. The relationship between the increase in extreme heat and climate change is at the heart of the debate and is reflected in the frequency with which these waves impact the population and the environment.

The coming weeks will be marked by uncertainty regarding temperature trends and the possible recurrence of intense heat waves. Meteorological monitoring will continue to be key to anticipating and minimizing the adverse effects of the next heat wave in Spain.
