New York Prepares for Summer Solstice 2026: Longest Day of the Year on June 21
The summer solstice, marking the astronomical start of summer in the Northern Hemisphere, will occur on Sunday, June 21, 2026. This day is known as the longest day of the year, with the most extended period of sunlight and the sun traveling along its northernmost path in the sky. According to the Old Farmer's Almanac, the solstice will officially begin at 10:42 p.m. EDT. Cities across New York will experience varying daylight durations, with Watertown receiving the most at 15 hours and 29 minutes, and New York City seeing 15 hours and 5 minutes. Meteorological summer, which began on June 1, will continue through the end of August, while astronomical summer will last until September 21. As the solstice passes, daylight hours will gradually decrease, leading to the winter solstice in December, the shortest day of the year.
