Spain had its hottest June on record last month, with an average temperature of 23.6 degrees Celsius (74.5 degrees Fahrenheit) “pulverising” the previous high, the Aemet national weather service said Tuesday.
The country’s “extremely hot” June 2025 “has pulverised records”, surpassing the normal average for July and August as well as the previous June record of 22.8C, set in 2017, the agency said on X.
Temperatures in southern Spain soared up to 46C on Saturday – another June high – while scientists said the Mediterranean Sea was warmer than usual at 26.01C on Sunday, another June record.

All in all, temperatures were 3.5C above normal in Spain this June; normal being the average for all months of June between 1991 and 2020 in this case.
With ten days left in the month, Aemet spokesperson Rubén del Campo was already warning that based on the data recorded up to that point and the forecasts for the rest of the month, June was going to be a record-breaking one. This has turned out to be the case.
Aemet starting collecting temperature data in earnest around the middle of the 20th century.
Spain’s national weather agency has sought to explain to online sceptics who say that ‘it’s always hot here in summer’ that the data proves that temperatures this high in June are not normal.
According to Spain’s System of Daily Mortality Monitoring (MoMo), 330 people have died in Spain due to heat-related causes this June. The only month of June where this figure was higher was in 2017, when 372 people died.
When we talk about this type of death, we are not referring to heat stroke , but rather to an excess of deaths that are attributed to an external factor , which in this case is heat.
