The astronomical first day of summer 2027 (June solstice) is Monday, June 21, 2027, at 14:11 UTC. The date can be a day earlier or later in your time zone. The meteorological first day of summer is always June 1.
A calendar year (365 days) is slightly shorter than the 365.24 days Earth takes to circle the Sun, so the June solstice arrives about six hours later each year and then jumps back after a leap year. That is why the date moves between two days.
Astronomical summer starts at the June solstice, which depends on Earth's tilt and orbit. Meteorological summer covers three whole calendar months starting on June 1, which makes weather statistics easier to compare year to year.
No. The seasons are opposite. When it is the first day of summer in the Northern Hemisphere, it is the first day of winter in the Southern Hemisphere.
It is Tuesday, June 20, 2028 (UTC).
