It is not spring yet in 2026: astronomical spring in the Northern Hemisphere starts on March 20, 2026, with the spring (vernal) equinox.

When spring 2026 actually starts

  • Astronomical spring 2026 in the Northern Hemisphere begins on Friday, March 20, 2026.
  • This start is defined by the spring equinox , when the Sun crosses the celestial equator and day and night are roughly equal in length.
  • Spring then runs until around June 21, 2026, when the summer solstice occurs.

Meteorological vs astronomical spring

  • Meteorological spring uses calendar months: March, April, and May in the Northern Hemisphere.
  • Astronomical spring depends on Earth’s orbit and tilt, starting at the equinox (March 20, 2026) and lasting about 92.8 days in the Northern Hemisphere.

So on today’s date (early February 2026), both definitions still place you in winter, even if the weather might occasionally feel springlike in some places. Do you care more about the calendar definition (March–May) or when it actually starts to feel warm where you live?
