The intrusion of a warm air mass, along with the presence of high pressure systems clearing the skies, will once again kick start the Spanish heatwave and lead to the second warm episode of April. Temperatures are expected to progressively rise across the country in the coming days, with highs exceeding 25 degrees in many areas of the Peninsula and the Balearic Islands, and reaching 30 degrees in the Ebro Valley, southern Galicia, and isolated parts of the southern Peninsula. These temperatures, 5 to 10 degrees above normal in the central and southern Peninsula and the Balearic Islands, and 10 to 15 degrees higher in the northern Peninsula, will affect the Canary Islands as well, with temperatures above 32 to 34 degrees, accompanied by dust and a very high risk of wildfires.
Although morning temperatures were still cold on Wednesday with frost in some areas, temperatures are expected to rise significantly across the country, reaching 18 to 20 degrees in many regions and up to 25 to 27 degrees in the Guadalquivir Valley and the southeast. The lingering effects of the Pierrick storm will continue to bring strong winds in the northeast and the Balearic Islands, and waves of up to three to four meters in Catalonia and the Balearic Islands. The weather map shows a progression of temperatures exceeding 25 degrees from Wednesday to the following Monday.
During Thursday, strong winds will begin to calm down but will remain gusty, particularly affecting the sea conditions along the Catalan and Balearic coasts. Showers may occur in eastern Mallorca and Menorca due to a low pressure system near Corsica and Sardinia. The rest of the country will experience clear skies and almost no rain, with temperatures rising notably in the north of the Peninsula and the Canary Islands. Temperatures are expected to increase by 5 to 8 degrees in most areas, with temperatures exceeding 20 degrees in the north, 25 degrees in the central region and the southern half, 28 degrees in southern Galicia and the Guadiana and Guadalquivir Valleys, and 32 degrees on the Canary Islands coast.
On Friday, clear skies are expected nationwide, with no rain and further temperature rises in the north of the Peninsula, the east, and the Balearic Islands. Some cooling is anticipated in southern Andalusia and, to a lesser extent, in the Canary Islands, where dust is expected to persist. Temperatures will exceed 25 degrees in the north and interior areas, with Ourense potentially reaching 30 degrees. The warmest city could be Ourense, with 30 degrees, and Santa Cruz de Tenerife may reach 32 degrees. In the Canary Islands, temperatures are expected to rise to 32 to 34 degrees in the southern part of the islands.
The weekend will see clear skies in the Canary Islands, although dust and high temperatures will persist. Despite slight temperature decreases, temperatures are expected to exceed 30 to 32 degrees, especially in the eastern islands. Throughout the following week, temperatures are forecasted to gradually drop, potentially normalizing by mid-week. In the Peninsula and the Balearic Islands, Saturday and Sunday will be very warm, with temperatures exceeding 25 degrees in many areas, 28 to 30 degrees in the east and south of the Peninsula, and over 30 degrees in the Ebro Valley and southern Galicia. Night temperatures will also be warm, though not as high as daytime temperatures, with some areas in the north experiencing temperatures 5 to 10 degrees above normal.
By Monday, there will likely be a significant temperature drop in the northern third of the country, with smaller decreases in the rest of the north, while the center and south may see slight increases. The rest of the week is expected to remain warm, especially in the central and southern regions of the Peninsula.
