YELLOWSTONE NATIONAL PARK — On Feb. 9, 1933, the coldest temperature ever recorded in Yellowstone National Park was documented at the Riverside Ranger Station.
The temperature plummeted to a frigid –66°F (–54°C) that day.
90 years later, the park has yet to record temperatures anywhere near that low although it has experienced lows of -40°F (-40°C) in some areas of the park this year.
During the winter in Yellowstone, temperatures usually range from zero to 20°F throughout the day. Sub-zero temperatures are also common, especially at night and at higher elevations.
“Since most of the park lies at an elevation of 6,000 feet (1829 m) above sea level or higher, unpredictability characterizes Yellowstone’s weather,” says the National Park Service.“
