Summer Solstice 2025: Everything You Need to Know

The summer solstice is an astronomical event that occurs twice a year when one of Earth’s poles reaches its maximum tilt toward the sun. The term "solstice" comes from the Latin "solstitium," meaning "sun stands still."

In 2025, the summer solstice will be on June 20th. For those in the Northern Hemisphere, this day marks the longest period of sunlight. NASA notes this happens when "the sun is directly over the Tropic of Cancer," located at 23.5 degrees north latitude.

While the Northern Hemisphere enjoys the start of summer, the Southern Hemisphere experiences the winter solstice, their shortest day of the year. The exact date of the summer solstice can vary, typically falling between June 20 and 22.

Following the summer solstice, the days gradually begin to shorten, leading up to the winter solstice on December 21st. The regions above the Arctic Circle experience the "Midnight Sun," where the sun never sets for several weeks.

The summer solstice in 2025 is on Friday, June 20, at 10:42 p.m. ET.

It marks the astronomical first day of summer in the Northern Hemisphere and the longest day of the year.

It occurs because of the Earth’s tilt on its axis, causing the Northern Hemisphere to be tilted most directly toward the Sun during this time.
