The solstice signifies the start of summer in the Northern Hemisphere. This year, the solstice arrived this morning at 6:51 A.M. EDT.
The timing of the solstice depends on when the Sun reaches its farthest point north of the equator.
In temperate regions, we notice that the Sun is higher in the sky throughout the day, and its rays strike Earth at a more direct angle, causing the efficient warming we call summer.
This summer solstice is the day with the most hours of sunlight during the whole year.
