Spain's State Meteorological Agency (Aemet) reported that June 2026 was the second warmest on record, with average temperatures reaching 23.2ºC, 3.2ºC above the average for the 1991–2020 period. The extreme heat resulted in nearly 900 deaths, according to the Ministry of Health's daily mortality monitoring system (MoMo). More than 600 of these deaths occurred during a severe heatwave from June 22 to June 24, which broke several daily temperature records.
Key Details
Aemet described the month as 'extremely hot,' a classification reserved for exceptionally abnormal weather events. The agency noted that only June 2025 recorded higher temperatures since its historical records began in 1961. The heatwave's intensity and geographical reach were particularly notable, impacting regions across the mainland and the Balearic Islands.
The MoMo system estimates excess mortality by comparing observed deaths with expected figures, linking them to episodes of potentially dangerous temperatures. This June marks the second highest heat-related mortality since records began in 2015. The heatwave trend is becoming increasingly evident, with earlier onset and greater severity noted in recent years.
Background
The impact of the heat on public health has raised concerns among officials as they prepare for future climate-related challenges. Aemet's data highlights the ongoing risks posed by rising temperatures, especially as heatwaves become more frequent in Spain.

The extreme weather conditions could lead to increased demand for healthcare services and emergency response resources. This may impact public spending and insurance sectors, particularly in regions most affected by the heat. Investors will watch for future climate data and government responses to address the health implications of rising temperatures.
