Groundhog Day is approaching Feb. 2. It is a time once we look to a sleepy woodchuck to inform us how rather more winter now we have to endure earlier than spring arrives. Punxsutawney Phil, probably the most well-known groundhog prognosticator in historical past, will emerge from his Pennsylvania burrow with some human help. If Phil sees his shadow, then we’re supposedly in for six extra weeks of winter. However there are some questions on Phil’s accuracy.
The Nationwide Oceanic and Atmospheric Administration checked Punxsutawney Phil’s monitor file final yr and located the fuzzy ambassador’s predictions missing. This yr, NOAA took a deeper dive into Groundhog Day outcomes and graded the work of 19 groundhogs and groundhog surrogates to find out the accuracy of their predictions. Spoiler: Phil got here in seventeenth.

NOAA ranks the groundhogs
NOAA set a couple of floor guidelines. The groundhogs and “various groundhogs” will need to have been prognosticating for a minimum of 20 years and should even have been lively as of Feb. 2, 2024. The opponents included 13 groundhogs, three taxidermied groundhogs, one never-seen creature presumed to be a groundhog, a prairie canine statue and a tortoise.
NOAA used knowledge from its Nationwide Facilities for Environmental Data, which maintains an archive of ocean, climate and local weather knowledge. The company in contrast the groundhogs’ monitor data with US March temperature averages from 2005 to 2024.
All hail Staten Island Chuck, a woodchuck on the Staten Island Zoo in New York Metropolis. Chuck, also referred to as Charles G. Hogg, topped the rankings with 85% accuracy. He famously bit the mayor in 2009 when Michael Bloomberg tried to coax him out for a Groundhog Day ceremony.
The subsequent-best groundhog was Common Beauregard Lee from the Dauset Trails Nature Heart in Jackson, Georgia with 80% accuracy. Third place belongs to Lander Lil, a bronze statue of a prairie canine in Lander, Wyoming. Lander Lil got here in at 75% accuracy. Groundhogs do not reside in Wyoming, however prairie canine do. The prognostication ideas are the identical. If Lander Lil “sees” a shadow on Groundhog Day, then extra winter is predicted.
How Punxsutawney Phil fared

Mojave Max is a desert tortoise just like the one pictured right here in a Nationwide Park Service picture.
General, 14 of the groundhogs had 50% accuracy or higher. Poor Punxsutawney Phil managed solely 35% accuracy, touchdown him close to the underside of the rankings. Not less than he is extra correct than Mojave Max, a desert tortoise on the Springs Protect in Nevada who took the final spot with 25% accuracy.
The rating won’t be honest to Mojave Max, although. The tortoise would not get paraded round on Groundhog Day. His predictions are primarily based on when he emerges from brumation (like hibernation for reptiles). Max will get up someday between February and April annually.
“Hotter temperatures, longer daylight and his personal inside clock are components recognized to contribute to his emergence yearly,” the Clark County Desert Conservation program mentioned. His look marks the unofficial begin of spring for southern Nevada.
Groundhog Day has been a convention at Gobbler’s Knob in Punxsutawney, Pennsylvania for the reason that late 1800s and it is nonetheless going sturdy. NOAA’s debunking of woodchuck climate forecasting would not detract from the enjoyable of the celebration. What Phil lacks in accuracy he makes up for in sheer fame, cuteness and charisma. So go forward and cheer for Phil, however possibly base your spring plans on a rodent from Staten Island quite than Punxsutawney.
