If the groundhog sees its shadow on Groundhog Day (February 2) , the old folklore says winter will last for six more weeks.

What the shadow “means”

  • Sunny sky → groundhog sees its shadow → legend says more winter.
  • Cloudy sky → no shadow → legend says early spring.

The idea comes from a Pennsylvania‑Dutch superstition: if the animal is startled by its own shadow, it scurries back into its burrow, “prolonging” winter; if it stays out, spring is coming sooner.

How accurate is it?

  • Studies and weather‑service analyses put Punxsutawney Phil’s accuracy around 39–40% , so it’s more fun folklore than reliable forecast.
  • In recent years, Phil has seen his shadow most of the time, which would “predict” more winter far more often than not.

Quick‑reference table

Shadow outcome| Folklore meaning| Typical weather implication
---|---|---
Groundhog sees shadow| Six more weeks of winter 111317| Continued cold, wintry conditions
Groundhog no shadow| Early spring 111317| Milder temperatures sooner

So if the groundhog sees its shadow, the playful “official” answer is: brace for six more weeks of winter , even if the real‑world weather often tells a different story.
