What is the name of the most famous groundhog that predicts the weather?

The most famous groundhog that predicts the weather is Punxsutawney Phil.

Phil is the central figure in Punxsutawney, Pennsylvania’s annual Groundhog Day celebration. Before sunrise on February 2, handlers bring him from his burrow to Gobbler’s Knob, where the ceremony’s Inner Circle interprets whether he has seen his shadow. The tradition says a shadow means six more weeks of winter-like weather, while no shadow predicts an early spring.

Punxsutawney’s event is the best-known of many groundhog festivals in the United States and Canada. Other famous weather-predicting groundhogs include Wiarton Willie in Ontario, Shubenacadie Sam in Nova Scotia, and Staten Island Chuck in New York. A common mix-up is treating these animals as rival names for the same groundhog: each represents a separate local celebration. The claim that the same Phil has predicted weather since 1887 is part of the festival’s playful folklore.
