Groundhog DayGroundhog Day is February 2


Important Facts:


  • Groundhog sees shadow, six more weeks of winter
  • No shadow, winter is over.


According to legend, the groundhog is supposed to awaken on February 2, and come up out of his burrow.

If it is a sunny day and the groundhog sees its shadow, according to folklore it becomes frightened and returns to its hole to sleep, and winter will last another six weeks. 

If it does not see its shadow, it remains outside because the worst of winter is over and warmer weather is on its way.


Why February 2? THE TRADITION

In the mid-18th century, German immigrants in Pennsylvania brought to the United States the tradition of watching the groundhog for signs of spring. They chose Feb. 2, the Christian holiday of Candlemas.  Candlemas is a "cross-quarter" day, about halfway between the winter solstice in December and the vernal equinox in March, and is celebrated in some cultures as the midpoint of winter.  Traditionally, it was believed that if Candlemas was sunny, the remaining six weeks of winter would be stormy and cold. But if it rained or snowed on Candlemas, the rest of the winter would be mild. If an animal "sees its shadow," it must be sunny, so more wintry weather is predicted:



The groundhog, often called a woodchuck, is the only mammal to have a day named in his honor.  Woodchuck and groundhog are common terms for the same animal, the rodent with the scientific name of Marmota monax. Most closely related to squirrels, groundhogs can actually climb trees and also swim. In the winter, not much happens. Groundhogs go into profound hibernation(almost like a coma), greatly reducing their metabolic rate, and their body temperature drops to just a few degrees above ambient temperature. The burrow where they hibernate, is below frost line so it never freezes in the burrow. 

Why do Groundhogs wake up?

The groundhog's internal clock is believed to be affected by annual changes in the amount of daylight. Hormonal responses to cyclic changes in production of melatonin, a sleep-related hormone, are thought by some to be the signal to wake up.


How accurate is the groundhog? 

According to organizers the groundhog is right 70-90% of the time.  According to meteorological records the groundhog gets it right only 35% of the time, which is actually worse than flipping a coin(50/50).
