Aragon recorded 235 deaths attributable to excess heat this summer

The summer of 2026 brought weeks of extreme heat and temperatures well above normal to Aragon. According to data from the Daily Mortality Monitoring System (MoMo), the episode was also reflected in mortality figures, with an estimated 235 temperature-attributable deaths between June and September. July had the greatest impact, with 109 estimated deaths.

The figures come after an especially hot summer in the region. Aemet confirmed in September that 2026 had been the warmest summer since records began in Aragon, with an average temperature 3.4 degrees above normal and as many as 61 days under heatwave conditions. There were also 64 tropical nights and 23 days with temperatures above 40 degrees.

The extreme heat was felt particularly strongly during the central months of summer. Zaragoza faced days with forecasts above 43 degrees and red-level warnings, while July saw several consecutive episodes of very high temperatures. August also remained under heat warnings, with maximum temperatures that could reach 41 degrees at times.

JULY, THE MONTH WITH THE GREATEST IMPACT

MoMo data show that June ended with 45 temperature-attributable deaths. The figure soared to 109 in July, the highest total of the entire period analyzed.

An additional 65 deaths were estimated in August, while September recorded 16. May, which also appears in the available series, recorded no temperature-attributable deaths. Thus, the total between June and September rose to 235 deaths.

WHAT IT MEANS FOR A DEATH TO BE ATTRIBUTABLE TO TEMPERATURE

MoMo data do not mean that the heat is listed as the direct cause of death on the death certificates of those 235 people. The system uses statistical estimates to calculate what share of mortality may be associated with temperatures.

For this reason, the number of temperature-attributable deaths does not necessarily coincide with excess mortality from all causes. These are different indicators that make it possible to analyze the impact heat episodes may have on the health of the population.
