The midpoint of summer officially occurs on August 7, 2025 (halfway between summer solstice and fall equinox). Depending on how your summer is going, may be either good news or bad news. But one thing is constant for nearly everyone in the Northern Hemisphere: the nights get longer and longer.

Summer is when the Sun reaches 90 degrees of longitude, and fall begins when the Sun reaches 180 degrees longitude. The midpoint, therefore, comes when the Sun reaches 135 degrees longitude and, in 2025, this occurs on August 7.

While August 7 is the official midpoint of summer, the traditional midpoint of the summer season actually occurs on August 1, which is marked on some Christian calendars as Lammas Day, one of the four traditional “cross-quarter” days midway between the solstices and the equinoxes.

“Lammas” is derived from the Old English “loaf-mass,” because it was once observed as a harvest festival. In fact, Lammas Day comes almost exactly six months after Groundhog Day, the traditional midpoint of winter. Celebrations of Lammas Day include baking of bread, and enjoying a feast with friends and family.

Note: the midpoint of summer and midsummer are different terms. Oddly, Midsummer is actually a reference to the first day of summer, summer solstice.

If you think about it, the length of daylight was rather substantial since about the middle of May. And the lowering of the Sun’s path across the sky and the diminishing of the daylight hours was rather subtle during the first half of the summer season.

So enjoy the last half of the summer season and get in as much of your favorite activities as you can before there’s a chill in the air and darkness wins out over daylight.
