The heat is leaving one of its harshest traces in recent years in Aragón. When August is not yet over, the Community has already accumulated 207 deaths attributable to high temperatures since the beginning of June, a figure that makes this summer the worst since 2022 and that far exceeds the records of the previous three years.
This is clear from the latest data from the Daily Mortality Monitoring (MoMo) system, dependent on the Carlos III Health Institute. Specifically, 45 deaths in June, 109 in July and another 53 so far in August 2026 are attributed to temperature. The balance of this last month is still provisional, since August has not ended.
The difference with respect to recent summers is considerable. In those same three months, 2025 counted 125 deaths attributable to temperature, with 15 in June, 36 in July and 74 in August. A year earlier, in 2024, there were 110, while in 2023 there were 144. In this way, the 207 deaths that 2026 has already accumulated represent 82 more than during the whole of June, July and August 2025, an increase of close to 66%.
2022 CONTINUES TO BE THE TOUGHEST SUMMER
Despite the sharp increase recorded this year, the figures are still far from those of 2022, a particularly tough summer in Aragon. Between June and August of that year, MoMo estimated 310 deaths attributable to temperature: 76 in June, 144 in July and 90 in August. If the period is extended to May and September, the balance rose to 322.
July is precisely behind much of the worsening of 2026. Its 109 deaths attributable to temperature are more than triple the 36 recorded in July 2025 and constitute the worst figure for that month since 144 in July 2022.
MoMo data does not represent deaths whose certificate necessarily shows heat as a direct cause. These are statistical estimates of mortality attributable to the effect of temperature, calculated by comparing the deaths that the model expects taking into account the temperatures with those that would be expected without this effect.
