Spain is facing its second major summer heat wave of the year with temperatures forecast to exceed 40°C in several regions [1, 2].
The extreme weather puts significant pressure on public health infrastructure and agricultural productivity during one of the hottest summers on record [1, 3].
The Agencia Estatal de Meteorología (AEMET) activated weather alerts on Saturday, June 20 [4]. While reports vary on the scale of the warnings, some data indicates alerts were activated in 14 autonomous communities [5], with seven of those specifically under orange alerts [1].
Forecasters expect the heat episode to last until Tuesday, June 23, before conditions begin to ease on Wednesday, June 24 [1, 4]. The most affected areas include the southern regions of Extremadura, Andalucía, and Castilla-La Mancha [2, 6].
Temperature projections vary by source. Some reports forecast maximums of 44°C in certain zones [4], while other data suggests peaks of 42°C [5]. The northern city of Bilbao is also expected to see extreme heat, with forecasts reaching 43°C [7].
This weather pattern is part of a broader trend of intensifying seasonal heat across Europe [3]. Officials said the population should take precautions as the heat remains suffocating across the affected territories [7].
“Spain is facing its second major summer heat wave of the year”
The recurrence of extreme heat waves early in the summer season suggests a volatile climatic pattern for 2026. The expansion of high-temperature alerts to northern cities like Bilbao indicates that the heat is not confined to the traditional southern corridors, potentially increasing the risk of heat-related illnesses in populations less adapted to such extremes.
