Over the years, looking to Pennsylvania’s most famous rodent to tell us when we can usher in spring has become a tradition. But, how often is Punxsutawney Phil right?

To many, Punxsutawney Phil is the official groundhog for Groundhog Day. And crowds of revelers will be waiting for his prediction.

Gobbler's Knob in Punxsutawney, Pennsylvania, as the world's most famous groundhog, Punxsutawney Phil, will emerge for his annual prognostication. Over 40,000 people are expected for this year's festivities.

If the weather-predicting groundhog sees his shadow, it allegedly means six more weeks of winter. If he doesn’t, it means an early spring. However, Punxsutawney Phil’s winter prognoses have only been right about 39% of the time.
