whenis summer

Summer usually means two slightly different things, depending on how you define it:

• Astronomical summer (Northern Hemisphere) :
  • Starts on the summer solstice, which in 2026 is on June 21.

* Ends around the September equinox, which in 2026 is on September 22.

• Meteorological summer (Northern Hemisphere) :
  • Simply the months of June, July, and August (June 1 to August 31).

If you’re in the Southern Hemisphere, those dates flip: summer runs roughly from December to February, with the summer solstice around December 21 marking the start of astronomical summer there.

So, if you’re asking “when is summer?” right now in 2026 and you’re in the Northern Hemisphere:

• Meteorological summer: June 1–August 31
• Astronomical summer: June 21–September 22
