Spain is facing an extreme heat wave with temperatures forecast to reach 42°C in several regions [1], [2].
The event poses a significant public health risk across the peninsula. Authorities said widespread warnings were issued as the extreme heat is linked to the broader effects of climate change [3], [4].
The Agencia Estatal de Meteorología (AEMET) has placed 15 autonomous communities under orange alert [5]. An additional two regions, the Balearic Islands and Murcia, remain under yellow alert [5].
Extreme conditions are most acute in Zaragoza, Córdoba, and Sevilla, where temperatures could hit 42°C [1], [2]. High temperatures are also expected in the Ebro valley, Galicia, and the valleys of the Tajo, Guadiana, and Guadalquivir [1], [2]. While some reports indicate temperatures between 40°C and 42°C across broad zones [2], other data shows a general range of 36°C to 39°C across the peninsula with peaks exceeding 40°C specifically in the river valleys [1].
This weather pattern follows a period of intensifying heat that began June 20 [6]. The severity of such events has historically led to high casualty rates; for example, heat-related deaths reached 1,028 in June 2024 [7].
Spanish authorities said they are monitoring the situation closely as the heat wave persists. AEMET said it continues to provide updates on the temperature spikes affecting the various autonomous communities to ensure public safety measures are implemented.
“Temperatures could reach up to 42°C in Zaragoza, Córdoba, and Sevilla”
The scale of the current alerts indicates a systemic struggle to manage extreme thermal events in Southern Europe. With a significant portion of the country under orange alerts and a history of high mortality during similar June heat waves, the event highlights the increasing vulnerability of Spain's infrastructure and public health systems to climate-driven temperature spikes.
