Meteorological accuracy of Punxsutawney Phil
According to Groundhog Day organizers, the rodents’ forecasts are accurate 75% to 90% of the time. However, a Canadian study for 13 cities in the past 30 to 40 years found that the weather patterns predicted on Groundhog Day were only 37% accurate over that time period. According to the StormFax Weather Almanac and records kept since 1887, Punxsutawney Phil’s weather predictions have been correct 39% of the time. The National Climatic Data Center has described the forecasts as “on average, inaccurate” and stated that “[t]he groundhog has shown no talent for predicting the arrival of spring, especially in recent years.”
