January 2022 is off to a frigid start, but December 2021 was one of Grandfather Mountain’s warmest on record.
According to data recorded at the official National Weather Service reporting station at Grandfather Mountain’s Mile High Swinging Bridge, December 2021 was the second warmest December in the park’s history.
The warmest temperature recorded last month was 60 degrees on Dec. 4, 18 and 28. That's three degrees shy of the mountain’s record December high of 63 degrees, recorded on Dec. 7, 1956.
The coldest temperature observed last month was 17 degrees on Dec. 12. The lowest temperature ever observed on Grandfather Mountain in the month of December was -21 degrees on Dec. 25, 1983.
The average high temperature for December 2021 was 50.7 degrees, with an average low of 35.2 degrees.
The mountain’s warmest December on record was in 2015, with an average high of 50.6 degrees and an average low of 36.5 degrees.
The Grandfather Mountain Stewardship Foundation records and reports data in two different ways:
The park maintains an automated weather station at the top of the Mile High Swinging Bridge. The N.C. State Climate Office assists the foundation in calibrating the machines and ensuring accuracy of data.
Grandfather Mountain has been an active member of the National Oceanic and Atmospheric Administration’s Cooperative Observer Program since 1955 by reporting daily temperature, precipitation and weather events from locations near the Mile High Swinging Bridge and the Nature Museum.
