Which hemisphere has its summer solstice at the June solstice?

The Northern Hemisphere has its summer solstice at the June solstice.

The June solstice occurs annually around 20–22 June, most often on 21 June. At that moment, the Northern Hemisphere is tilted toward the Sun, producing its longest period of daylight and marking its astronomical summer solstice.

The same event is the winter solstice in the Southern Hemisphere, where it brings the shortest daylight period of the year. This opposite seasonal effect is why “June solstice” is often a clearer term than “summer solstice,” which depends on the hemisphere being discussed.

During the June solstice, the Sun is directly overhead at the Tropic of Cancer, approximately 23.44° north latitude. The Eastern and Western Hemispheres are geographic divisions and do not determine whether a solstice is summer or winter. Near the Arctic Circle, the date can also bring the midnight Sun, when daylight lasts through local midnight.
