When does summer start? Dates through 2036
How the date is set
Astronomical summer in the Northern Hemisphere begins at the June solstice, which falls on June 20 or 21 in most years.
At the June solstice the Sun reaches its northernmost point in the sky, giving the Northern Hemisphere its longest day of the year.
Good to know
- Meteorologists count summer from June 1 instead.
- In the Southern Hemisphere the June solstice is the start of winter, and summer begins at the December solstice.
