The summer solstice 2027 occurs on Monday, June 21, 2027, at 10:11 a.m. EDT (7:11 a.m. PDT, 14:11 UTC), according to the U.S. Naval Observatory. It is the longest day of the year in the Northern Hemisphere.
The longest day is not the day of the earliest sunrise or the latest sunset. In New York City in 2027, the earliest sunrise comes on Monday, June 14, and the latest sunset on Sunday, June 27, a week on either side of the solstice.
Earth is near its farthest point from the Sun during the summer solstice: it reaches aphelion two weeks later, on Monday, July 5, 2027, at 05:06 UTC. Summer is caused by the tilt of Earth’s axis, not by distance. In Sweden and Finland, Midsummer is celebrated four days after the solstice, on Friday, June 25, 2027.
