The first day of summer in 2022 is Tuesday, June 21, in the Northern Hemisphere, at 5:14 a.m. EDT, on Tuesday, marks the 2022 summer solstice.
This is the precise moment when the North Pole tilts closest to the sun, making the sun appear at its highest point in the sky of the year.
At that moment on Tuesday, the sun will be directly above the Tropic of Cancer. That’s the farthest north the sun moves in the sky, which is why the days close to the solstice have the most daylight of the year for n the Northern Hemisphere.
The reason the Earth has solstices, equinoxes and seasons is because the Earth is tilted on its axis. According to Earthsky, Earth’s Northern and Southern Hemispheres trade places in receiving the sun’s light and warmth every six months as the Earth revolves around the sun.
