Spain remains under a persistent heatwave, with temperatures above 40°C in many regions. AEMET warns of severe storms, strong winds, and hail. Nights bring little relief, especially in the south and Mediterranean.
Large parts of Spain are enduring another stretch of extreme heat, with the Agencia Estatal de Meteorología (AEMET) maintaining orange alerts across the east, south, and Balearic Islands. Maximum temperatures are expected to reach between 37°C and 41°C, and in some areas, thermometers will again surpass 40°C. The ongoing heatwave shows no sign of easing, and authorities are now warning of a new threat: severe afternoon storms, some with intense winds and hail.
According to AEMET, the combination of very warm surface air and growing atmospheric instability will trigger stormy showers, especially in the eastern and southeastern interior. These storms are forecast to be highly localized but could be intense where they strike, bringing the risk of hail and sudden, powerful gusts. The agency highlights the interior of Castellón, Tarragona, and Valencia, as well as northern Murcia, eastern Andalucía, and southeastern Albacete, as the most at-risk zones for electrical activity, hail, and damaging winds.
While the sun will dominate much of the country, the afternoon will see cloud development in several autonomous communities, increasing the likelihood of storms. In Castilla-La Mancha, Albacete and eastern Cuenca may experience downpours mixed with dust due to suspended particles, while the interior mountains of Murcia could see storm cells with hail and strong gusts. The Balearic Islands will continue to face high temperatures, calima, and tropical nights, whereas the Canary Islands remain largely stable.
Nighttime offers little respite. Minimum temperatures are forecast to stay above 20°C across much of the south, the Mediterranean coast, and the Balearics, resulting in so-called 'tropical nights.' In some Mediterranean coastal areas and the Guadalquivir valley, lows may not drop below 25°C, creating what meteorologists call a 'torrid night.' Madrid is again among the regions expecting the highest temperatures, with much of the area likely to see 39–40°C, and even the Sierra exceeding 35°C. Navarra's Ribera could approach 38°C, and the heat will persist in Castilla y León, the Basque Country, La Rioja, Aragón, and Extremadura, where temperatures are set to rise further compared to previous days.
Recent weather patterns have brought not only heat but also increased storm risk, particularly in the southeast. For context, a recent report on severe storms and hail in Valencia and Murcia highlighted the growing frequency of such events during heatwaves, underscoring the need for ongoing vigilance.
Spain's heatwaves have become more frequent and intense in recent years, often accompanied by unpredictable storm activity. The combination of high temperatures and sudden storms can disrupt daily life, impact agriculture, and increase the risk of wildfires. AEMET continues to monitor the situation closely, urging residents in affected areas to stay informed and take necessary precautions as the extreme weather persists.
