The Agencia Estatal de Meteorología (AEMET) issued a special warning regarding the arrival of Spain's first summer heat wave starting this Saturday.
The extreme weather event poses significant health and infrastructure risks as temperatures are expected to deviate sharply from seasonal norms across the Spanish peninsula and the Balearic Islands.
Forecasters expect temperatures to rise between five and 10 °C above usual values for this time of year [1]. The heat wave will bring intense daytime and nighttime temperatures to several regions, with notable impacts expected in Sevilla, Andalusia, and Aragon [2, 3].
In the Guadalquivir valley, daytime highs are projected to reach up to 43 °C [4]. The agency said that the heat is typical of the "canícula," or the peak of summer heat [2].
Nighttime temperatures are expected to remain high, preventing the usual nocturnal cooling. An AEMET spokesperson said, "No se bajará de 25 grados" [3]. In certain parts of Andalusia, nighttime lows are forecasted to remain above 27 °C [4].
Jorge Rey said, "Si te gusta el calor tropical, este es tu año" [3]. The warning emphasizes the arrival of these tropical conditions earlier than typical patterns might suggest for the region.
“"No se bajará de 25 grados"”
The arrival of a high-intensity heat wave with minimal nighttime cooling increases the risk of heat-related illnesses and puts additional strain on the electrical grid due to air conditioning demands. When temperatures do not drop below 25 °C at night, the human body cannot recover from daytime heat stress, which can exacerbate chronic health conditions.
