Spring 2022 in Northern Hemisphere begins on Sunday, March 20 and ends on Tuesday, June 21.

 During early spring, the axis of the Earth is increasing its tilt relative to the Sun, and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly, causing new plant growth to “spring forth,” giving the season its name.

At the spring, or vernal, equinox, days are approximately 12 hours long with day length increasing as the season progresses.

Swedish meteorologists define the beginning of spring as the first occasion on which the average daytime temperature exceeds zero degrees Celsius for seven consecutive days, thus the date varies with latitude and elevation.
