The 2025 summer solstice takes place on June 20, heralding the onset of astronomical summer and the longest day of the year.

The summer solstice, the longest day of the year in the Northern Hemisphere, falls on June 20 this year in North America, and June 21 in Europe.

Temperatures in Northeast Ohio have been trending below normal for much of June — but that’s not stopping the first day of summer from showing up right on schedule.
