Spain's current heat wave is forecast to end on Thursday, June 25, 2026 [1].
While the official heat wave concludes, the transition period remains dangerous for public health as residual heat keeps temperatures elevated across the region.
The Agencia Estatal de Meteorología (Aemet) said that high or very high temperatures between 36 and 39 degrees Celsius will continue to affect much of the eastern third of peninsular Spain [2]. This weather pattern also extends to southern Gran Canaria [2].
Specific areas facing these conditions include the valleys of the Ebro, Tajo, Guadiana, and Guadalquivir, as well as the coasts of Valencia and Murcia [3]. However, some regions will see relief, including the Cantabrian area, the Alborán coast, and various high-altitude zones [3].
Weather officials said a cooler Atlantic air mass is arriving to break the heat wave [4]. Despite this shift, the impact remains significant enough that alerts are still active for six autonomous communities [5].
The arrival of the Atlantic air mass represents a turn in the weather pattern, but the lingering heat ensures that the risk of heat-related illness persists in the eastern corridors of the peninsula [4].

The conclusion of a heat wave does not imply an immediate return to seasonal norms. The persistence of 36-39 degree temperatures in eastern Spain indicates that while the atmospheric driver of the heat wave is shifting, the thermal inertia in the land and the slow arrival of Atlantic air will keep the region in a high-risk state for several more days.
