Summer 2026 in the Northern Hemisphere starts on June 21, 2026, so from today (January 24, 2026) it’s about 5 months away, roughly 150 days give or take depending on your exact location and time of day.

If you want a quick way to think about it:

  • Late January to late February: 1 month.
  • Late February to late March: 2 months.
  • Late March to late April: 3 months.
  • Late April to late May: 4 months.
  • Late May to late June: a bit under 5 full months total until the solstice around June 21.

Astronomically, “summer” usually means the period from the summer solstice (around June 21) to the autumn equinox (around September 22–23) in the Northern Hemisphere. So: you’re in the home stretch of winter now, with spring coming in a couple of months and then summer following on its heels.
