The State Meteorological Agency (AEMET) has alerted about an imminent heatwave that will affect Spain, with very high day and night temperatures that could occasionally reach 45 degrees. This situation is expected to last until next Thursday. However, the agency has clarified that in the Canary Islands, temperatures will remain around 30 degrees, particularly affecting the eastern islands.
AEMET spokesperson Rubén del Campo explained that while high temperatures will be felt in much of the peninsular territory and Balearic Islands, the most affected areas will be the east and south of the Peninsula, allowing the islands to escape the most suffocating heat. A generalized drop in temperatures is anticipated for Friday and Saturday, offering relief with milder conditions, although a new temperature rise is not ruled out for the following week.
This heat episode will be accompanied by dust in suspension, leading to dust haze and a deterioration of air quality. AEMET has also warned of a very high or extreme fire risk across most of the territory during the week. Rainfall will be scarce, although storms are expected in eastern peninsular areas, especially in mountainous regions. These storms may be dry but accompanied by lightning, hail, and strong gusts of wind.
For Tuesday, a temperature rebound is expected, with very warm nights in the Mediterranean region, exceeding 25 degrees in cities like Barcelona, Palma, Valencia, and Murcia. During the day, temperatures will surpass 36 degrees in much of the east, center, and south of the Peninsula and the Balearic Islands, and 39 to 40 degrees in the interior of Aragon and Catalonia, potentially reaching 43 or 44 degrees in the Guadalquivir valley and the southeast.
In the Canary Islands, mostly clear skies are expected with morning cloudy intervals in western Lanzarote and Fuerteventura, and in low-lying northern areas of other islands. Light dust haze is predicted at high altitudes, with temperatures slightly decreasing inland. Locally, temperatures will reach or exceed 30-32 °C in Gran Canaria and 30 °C in southern Fuerteventura. Moderate northeasterly winds are expected, with strong gusts on exposed coasts.
On Wednesday, nighttime temperatures will rise inland, resulting in very warm nights across much of the country. During the day, the heat will be intense and widespread, exceeding 36 degrees in the northern Peninsula and 38 degrees in the south, with highs of 38 to 40 degrees in large areas and up to 42 degrees in the southeast and Andalusia. Dust haze will persist, along with the possibility of dry storms with strong winds and hail.
In the Canary Islands, Wednesday will remain mostly clear with light dust haze at high altitudes. Temperatures will show little change or a slight increase in maximums, locally reaching or exceeding 30-32 °C in Gran Canaria and 30 °C in Fuerteventura. Moderate northeasterly winds are expected, with strong intervals.
From Thursday onwards, AEMET anticipates that intense heat will continue in most of Spain, with notable thermal rises possible in the Mediterranean area, exceeding 42 to 44 degrees, and even 45 degrees locally in Murcia capital. In the Canary Islands, little change is expected, with slight increases in inland maximums, reaching or exceeding 30-32 °C in Gran Canaria and 30 °C in Fuerteventura and Tenerife.
For Friday and the weekend, uncertainty increases, but a thermal decrease from the western Peninsula is likely, extending to the rest of the country on Saturday. Friday will still be hot in the eastern interior and the Balearic Islands, but on Saturday temperatures will moderate, falling below the normal average in the west. In the Canary Islands, Friday is expected to have similar temperatures, with a slight decrease in inland maximums and moderate northeasterly winds.
In summary, stable weather will prevail in the Archipelago with strong trade winds in exposed areas. There will be cloudy intervals in the north and clearer skies in the south, with maximums potentially exceeding 30 to 32 degrees in the mountainous and eastern islands.
