A Storm moon, according to weather folklore, is the moon which occurs
in March during shifting weather patterns in the northern hemisphere.
This is the month when Spring finally arrives, around the time of the
Equinox, and we see new life begin to spring forth.
As the temperature begins to warm and the ground begins to thaw,
earthworm casts appear, heralding the return of the robins. The more
northern Native American tribes knew this Moon as the Full Crow Moon,
when the cawing of crows signaled the end of winter; or the Full Crust
Moon, because the snow cover becomes crusted from thawing by day and
freezing at night.
March’s Full Moon was traditionally called the Full Worm Moon
by Native Americans who used lunar phases to track the seasons.
Colonial Americans also used these names, especially those of the local
Algonquin tribes who lived between New England and Lake Superior.
At the time of this Moon, the ground begins to soften enough for
earthworm casts to reappear, inviting the return of robins and migrating
birds—a true sign of spring.
Roots start to push their way up through the soil, and the Earth experiences a re-birth as it awakens from its winter slumber.
In some regions, March’s full Moon is instead known as the Sap Moon,
as it marks the time when maple sap begins to flow and the annual
tapping of maple trees begins. When a second full Moon occurs in March,
it is called the Full Sap Moon. The second full Moon in a single month
is more generally called a Blue Moon.
The Full Sap Moon, marking the time of tapping maple trees, is
another variation. To the settlers, it was also known as the Lenten
Moon, and was considered to be the last full Moon of winter.
It is also called seed moon, moon of winds, crow moon, moon of the snow-blind, and Full Worm Moon.
