When does spring start in Denmark?

Three ways to count the start of spring.

Answered at: Checked at:

Short answer

In Denmark calendar spring covers March, April and May, so 1 March is the first day of spring. Astronomical spring starts later, at the spring equinox on 20 March. If you count by temperature, with night minimums between 0 and 10 °C, spring begins around 25 March. A popular rule of thumb says it is spring when the morning temperature follows the clock: 7 °C at 7 o'clock, 8 °C at 8 o'clock and so on.

Weather and seasons

Why

  1. Weather statistics use March, April and May as spring.
  2. The spring equinox falls on 20 March.
  3. By temperature, spring usually arrives around 25 March.

Details

Spring 2026 had a mean temperature of 8,2 °C, against a 1991–2020 normal of 7,3 °C.

Tip

Pack for night frost in March and April, even if the forecast promises 15 °C in the afternoon.

What may differ

The temperature-based start of spring moves from year to year, so a cold March can push it into April.

Common misconception

Spring in Denmark officially starts on the spring equinox.

What actually happens

In weather statistics spring starts on 1 March; the equinox on 20 March is the astronomical start.
