June 2025 Was Western Europe's Warmest June on Record
When dangerous heat and high UV arrive in June instead of August, the 'I'll start sunscreen in midsummer' habit leaves weeks of skin unprotected.
June 2025 was the warmest June on record for western Europe, averaging 20.49C, which is 2.81C above the 1991 to 2020 average, driven by two early-summer heatwaves.
Climate scientists at the Copernicus Climate Change Service link the record warmth to early-summer heatwaves, and dermatology guidance more broadly stresses that UV exposure, not just heat, is what damages skin, so the protective season should track the UV index rather than the calendar.
Questions we get a lot
Does record heat mean I need sunscreen earlier in the year?
Heat and UV often rise together in early summer, and June 2025 set a western Europe warmth record according to Copernicus. UV, not temperature, is what damages skin, so checking the daily UV index is the best trigger for daily sunscreen. When heatwaves arrive in spring or early summer, protection should start then rather than waiting for midsummer.
How hot was June 2025 compared with normal?
Copernicus reported that western Europe averaged 20.49C in June 2025, which is 2.81C above the 1991 to 2020 average, making it the warmest June on record for the region. Two early-summer heatwaves were the main drivers. That kind of anomaly underlines how summer conditions are arriving earlier.
