June solstice in 2025: All you need to know When is it? A solstice isn’t a whole day. Instead, it’s the moment when the sun is farthest north in our sky. In 2025, the solstice moment will fall at 2:42 UTC on June 21 (9:42 p.m. CDT on June 20). What is it? At the June solstice, the sun reaches its northernmost point. This point is on the celestial Tropic of Cancer, a parallel around the sky, 23.5 degrees north of the celestial equator. At this solstice, the Northern Hemisphere is most tilted toward the sun, by the maximum angle of 23.5 degrees. Conversely, the south is most tilted away, by the same amount. What are its main effects? At the June solstice, no matter where you are on Earth, the sun rises and sets farthest north on your horizon. The sun is directly overhead at local noon as viewed from the Tropic of Cancer. Throughout the Northern Hemisphere, the sun is high in the sky and closest to being overhead at local noon. What about day length?: For us in the Northern Hemisphere, the June solstice marks the shortest nights and longest days of the year. For the Southern Hemisphere, however, it marks the longest nights and shortest days. After this solstice, the sun will begin moving southward in our sky again. https://earthsky.org/astronomy-essentials/everything-you-need-to-know-june-solstice/
