In the Northern Hemisphere, the summer solstice typically occurs during June.
This is the June solstice, the astronomical event that begins or marks the height of summer depending on the calendar tradition being used. It occurs when the Northern Hemisphere is tilted most strongly toward the Sun, producing the year’s longest daylight period and shortest night there.
The solstice does not always fall on the same civil-calendar date. Under the Gregorian calendar, it generally occurs on June 20 or June 21, though the exact date and time depend on the year and time zone. The Sun is then directly overhead at the Tropic of Cancer, at approximately 23.44 degrees north latitude.
June should not be confused with meteorological summer, which begins on June 1 in the Northern Hemisphere. Astronomical summer is tied to the solstice and equinoxes, while meteorological seasons divide the year into convenient three-month periods. Another source of confusion is geography: in the Southern Hemisphere, the June solstice is the winter solstice, and its summer solstice arrives in December.
