The March Equinox marks the moment where the Sun crosses the equator (an imaginary line in the sky above the equator) from south to north and usually occurs between March 19-21 every year. Both the March and September equinoxes are when the Sun shines directly on the equator making night and day nearly equal. This equinox is the transition from winter to spring in the Northern Hemisphere but the reverse in the Southern Hemisphere (summer into fall). Various cultures celebrate March equinox as a time of rebirth. Many spring festivals are timed to coincide with the equinox and some religious events (Passover and Easter) use specific calculations based on the equinox to help determine the exact day of the event.
Meteorologists however start spring on March 1 rather than by the March Equinox. The reason is that they divide the year into four quarters to make it easier to compare data and compile statistics. Meteorological seasons use annual temperature cycles rather than the position of the Sun. While astronomers follow the position of the Sun regarding equinoxes and solstices, meteorologists use the calendar to prevent problems since the dates of equinoxes and solstices can vary each year.
Early spring is when the Earth’s axis increases its tilt relative to the Sun resulting in more daylight for that part world where it spring is occurring. It is a time when the increased warmth results in more plant growth (spring forth as it used to be said and how spring got its name). The resulting warmth also makes snow melt causing streams to swell and frosts to diminish. For areas that get little or no snow, ground temperatures will increase quickly as well. Despite spring beginning in March, in areas where there is no snow early plant growth can begin as early as February (or August down below). Arctic zones may not experience spring until May.

Due to the reversal of seasons in the Southern Hemisphere, Easter is celebrated in Autumn. The Allhallowtide (Halloween, All Saints’ Day, All Souls’ Day) is celebrated in Spring.
Despite the change of the seasons–both calendar and meteorologically speaking–winter does continue in many places. And with it can come unpredictable weather which my favorite feline Garfield illustrates it perfectly. Garfield is outside. First it is warm and sunny. Then cold and rainy. Then back to warm and sunny. And then rain again and then another dry day. Finally, Garfield yells in exasperation “Will you make up your mind?” The next frame is split with one half having rain and the other half sunny. And it is more accurate than most of us want to believe.
There are two sayings that get the season right, courtesy of The Old Farmer’s Almanac:
Bluebirds are a sign of spring; warm weather and gentle south breezes they bring.
One swallow does not make a spring.
Welcome to Spring!
