MADRID / RankWire.AI / – Mainland Spain experienced its hottest summer since the start of official records in 1961, with an average temperature of 24.5 degrees Celsius during June, July, and August. Data released by the national meteorological authority confirmed that seasonal temperatures exceeded the previous record set in 2025 by 0.3 degrees Celsius and went beyond the 1991–2020 climate baseline by 2.4 degrees Celsius. The summer’s record heat was driven by heatwave conditions that affected two-thirds of the meteorological summer period.
According to figures from the State Meteorological Agency, the country experienced an unprecedented total of 61 heatwave days during this three-month stretch. This total significantly surpasses the 41 heatwave days recorded during summer 2022, the previous high. Analysts highlight that all ten of Spain’s hottest summers have occurred in the 21st century, underscoring an accelerating warming trend across southern Europe.
This extreme heatwave placed severe stress on public health and infrastructure across both northern and southern regions. The epidemiological mortality data from the Carlos III Health Institute estimates that over 5,000 lives were directly lost due to heat exposure between June and August. This figure marks the highest total recorded since the health agency began standardized heat-related mortality tracking in 2015.
National Meteorological Agency Confirms Record-Breaking Seasonal Temperatures
High temperatures also led to critical environmental conditions across forests and rural farmland. Data from the European Forest Fire Information System indicates that nearly 296,000 hectares of land were burned by wildfires through early September. Prolonged dry spells depleted regional reservoirs, creating operational difficulties for agricultural irrigation and hydroelectric plants, as Spain’s hottest summer on record unfolded.
Monitoring stations reported that extreme thermal conditions extended beyond the typical summer months. On September 2, a station in El Granado, in southwestern Spain, recorded a peak temperature of 45.7 degrees Celsius, tying the national September temperature record. Weather experts confirmed that high heat persisted from late May into early September across multiple autonomous communities.
Wildfires Consumed Over Two Hundred Ninety Thousand Hectares This Summer
Responding to these official findings, government ministers presented the data to parliament, urging for broader environmental protections. Minister for the Ecological Transition Teresa Ribera called on parliamentary groups to back comprehensive legislation aimed at climate adaptation, emergency infrastructure, and drought resilience.
Meteorological agencies and health authorities will keep monitoring temperature trends and environmental impacts through the upcoming autumn. Official statistics and environmental data will continue to be accessible via government portals, as public health officials evaluate long-term adaptation strategies. Regional authorities are also coordinating resource management to address ongoing agricultural and environmental challenges.
