Overview

• MoMo data show 122 heat-attributable deaths in the Comunitat Valenciana so far in August, contributing to 309 deaths from June 1 to August 20, the highest summer toll there in a decade.
• The deadliest stretch in Valencia this month occurred on August 18–20, with daily tallies of 19, 21 and 19 deaths, as exceptionally warm nights kept temperatures above 25°C in hundreds of locations and above 30°C at 19 stations.
• Six municipalities in the Sierra Sur de Sevilla are imposing nightly water cuts from 23:00 to 08:00, leaving about 17,000 residents without supply as low reservoir levels and pumping failures persist.
• Analyses reported that by August 18, Spain had already recorded more heat-related fatalities than during the entire summer of 2024, underscoring the intensity and persistence of this year’s heat.
• National monitoring also reflects a sharp July spike, with 1,060 heat-attributable deaths recorded, as officials and scientists stress that MoMo captures extreme-heat mortality while MACE estimates include moderate heat as well.
