When and What Is the Summer Solstice?

Solstices are opposite on either side of the equator, so the Summer Solstice in the Northern Hemisphere is the Winter Solstice in the Southern Hemisphere and vice versa.

First Day of Summer?

The first day of spring, summer, fall and winter can either be defined using astronomical events like solstices and equinoxes, or they can be determined based on meteorological factors, average temperatures.

In the USA and some other areas in the Northern Hemisphere, the Summer Solstice marks the first day of summer. However, the official date for the first day of summer varies depending on the country's climate.
