Shubenacadie Sam
First groundhog to predict spring each Groundhog Day.
Shubenacadie Sam, a female groundhog, calls the Shubenacadie Wildlife Park in Nova Scotia home. Each February 2 at 8:00 a.m. AST, a crowd watches for her shadow to predict whether spring will arrive early. Because Nova Scotia sits in the Atlantic Time Zone, Sam’s forecast is the first Groundhog Day prediction made anywhere in North America.

Lore & Background
The Shubenacadie Sam tradition at the wildlife park began about 1987 and differs from most other famous groundhogs as Sam is not woken from hibernation for Groundhog Day. By 2018, four groundhogs had served as 'Shubenacadie Sam' since the practice began in Nova Scotia, as groundhogs usually live 10–15 years in captivity. In 2021, a 7-year-old female groundhog named 'Samantha' assumed the prediction duties. Park employees have served as caretaker for over 20 years, providing breakfast of yogurt and melon, and reading to the groundhog, who has been designated an advocate for Family Literacy Day.
The ceremony draws an early-morning festive crowd of about 200 families and visitors, sometimes heralded by a groundhog mascot, bagpiper, and town crier. The wildlife park, usually open only on weekends in winter, changes its seasonal hours for the annual ritual. The ceremony was held virtually by web streaming during the COVID-19 pandemic in 2021 and 2022, but live gatherings resumed in 2023.
Reader's Guide
Shubenacadie Sam holds a unique place among weather-predicting groundhogs as the first to make a prediction each Groundhog Day, owing to Nova Scotia's Atlantic Time Zone. The tradition arrived with German Foreign Protestant immigrants in the 1750s who settled around Lunenburg, where the day was known as 'Daks Day' (from the German dachs for badger). Sam's predictions have been studied for accuracy: a 2018 review by meteorologist Cindy Day gave Sam an accuracy rate of about 45%, compared to 39% for Punxsutawney Phil and 25% for Wiarton Willie. However, a 2021 Lakehead University study of 20 years of Sam's predictions found a 65% accuracy rate, better than Phil's 52% and Willie's 54%, though still below the 75% considered reliable. The study concluded that groundhog day predictions are random with an average success rate of only 50-50. Sam inspired a children's book in 2022, with pages displayed around the park offering a groundhog tour. In 2018, Sam bit a CBC reporter who grabbed the groundhog to stop it from climbing out of its enclosure.
