How does Groundhog Day work? What happens if the groundhog sees its shadow?
Spring officially starts 20 March but depending whether or not a groundhog sees its shadow, it’s believed to foretell how soon spring weather will arrive.
In the United States, the tradition of using a four-legged, furry creature to divine when winter would end, and spring would arrive has been going on since German and Dutch immigrants brought it with them from Europe. However, in the old country other animals were used, but the plentifulness of groundhogs made them a good candidate in the US.
Technically, the official start of spring is 20 March, but the weather doesn’t always follow the celestial calendar. Thus the reliance on an oracle more in tune with Mother Nature, at least that is what is believed, and the birth of Groundhog Day.
Nowadays, it is pretty hard to find anybody who has never heard of the celebration thanks to the 1993 movie ‘Groundhog Day’ starring Bill Murray. The number of people that flock to Gobbler’s Knob in western Pennsylvania each year skyrocketed after its release to see in person the most famous of the groundhog forecaster, Punxsutawney Phil, the other star of the movie.
But how does he, and his peers, foresee the weather to come?
The Groundhog Day prediction depends on seeing a shadow
Groundhogs fatten themselves up in the fall before they lay down for a long winter’s sleep. In February, the males come out of their burrows to look for a mate prior to going back again to slumber some more. In the case of Groundhog Day, they’re given a little nudge to wake up.
A groundhog’s ability to divine the weather to come is based on whether or not he sees his shadow upon emerging from his dwelling. Clear skies bode ill for the weeks ahead as the groundhog will see his shadow and scurry back into his hovel meaning that there will be six more weeks of winter cold in store. Should the skies be cloudy, the opposite will occur, and spring will come early, at least according to superstition.
The earliest recorded mention of this come from the Punxsutawney Spirit newspaper from 1886, which read: “up to the time of going to press, the beast has not seen its shadow.” However, the first official Groundhog Day celebration was the following year. In most cities, the mystical groundhog whispers into the mayor’s ear, Phil has a whole entourage called the “Inner Circle” who decipher his prediction.
How accurate are Punxsutawney Phil’s predictions?
The statistical probability of getting a coin toss right is 50 percent. But over his nearly 140 years in the weather forecasting business, Punxsutawney Phil has been subpar in his predictions according to NOAA. Over the past decade, he’s gotten just three out of ten correct. Two of those predicted an early spring and one he foretold six more weeks of winter. Last year’s prediction of an extended winter was a mixed bag.
To be fair though, he’s held to a high standard as the most well-known groundhog, tasked with predicting the weather for the entire nation when he only sees his shadow, or not, in Punxsutawney in western Pennsylvania. Additionally, unlike his truly wild counterparts that helped foretell the coming or not of spring in the past, Phil lives in a climate-controlled environment where the light and temperature are consistent year-round and does not hibernate.
Other illustrious groundhogs
Phil isn’t the only Groundhog that makes an annual prediction of whether spring is just around the corner, or we’ll have to wait another six weeks for a reprieve from wintery weather. Across the US there are several other oracle Groundhogs, and although not as tenured, Staten Island Chuck has had a better record getting 80 percent on the mark since starting in 1981.
Chuck has had a couple of moments in the national spotlight, like the time he bit Mayor Michael Bloomberg in 2009. Or when he got tossed by Mayor Bill de Blasio in 2014, dying the following day, but his handlers said that it “appeared unlikely” it was the mayor’s fault.
There have been other memorable mishaps that have made national headlines such as Jimmy in Sun Prairie, Wisconsin in 2015. When he was held up to Mayor Jonathon Freud’s ear, he was apparently not happy to have been disturbed from his slumber and promptly took a bite.
