Answer by Hank W. The average length of the northern hemisphere summer, calculated as the average time from the June solstice until the September equinox, is about 93 days and 15Â½ hours. The average length of the southern hemisphere summer, calculated as the average time from the December solstice until the March equinox, is about 89 days.
Summer is not over. We've got weeks left until September 22, the last official day of the season. Everyone, please, stop the rush to fall.
