Every February 2, on Groundhog Day, Sam's shadow is closely observed at 08:00 AST to make the traditional prediction whether there will be an early spring.
Due to Nova Scotia's Atlantic Time Zone, Sam makes the first Groundhog Day prediction in North America.
[1] The prediction ceremony draws an early-morning festive crowd of about 200 families and visitors to the wildlife park, sometimes heralded by a groundhog mascot, bagpiper and town crier.
[7] By 2018, four ground hogs had served as "Shubenacadie Sam" since the practice began in Nova Scotia, as groundhogs usually live 10-15 years in captivity.
[12] Shubenacadie Sam's prediction, like all weather-predicting groundhogs, bears little relation to seasonal weather trends as it is based on random location conditions, according to Meteorologist Cindy Day.
