The Science Behind the Summer Solstice

The summer solstice occurs when the Sun is at its highest point in the sky. This is because the Earth's axis is tilted away from the Sun at an angle of 23.5 degrees. The tilt causes the Sun to appear higher in the sky during summer than it does during winter.

The summer solstice is the longest day of the year because the Sun is up for a longer period of time. In the Northern Hemisphere, the amount of daylight on the summer solstice can range from 15 to 17 hours. In the Southern Hemisphere, the amount of daylight on the summer solstice can range from 11 to 13 hours.
