when is spring in america

Spring in the United States usually starts in March and runs through May, but there are two common definitions people use.

When is spring in America?

• Astronomical spring (the one tied to the Sun and the equinox) typically runs from about March 20 or 21 to June 20 or 21 in the U.S.

• Meteorological spring (used by weather and climate experts) is simply March 1 through May 31.

So if you hear “first day of spring” on the news, they usually mean the spring (vernal) equinox around March 19–21, but many meteorologists already call it spring starting March 1.
