YELLOWSTONE NATIONAL PARK WEATHER

Yellowstone National Park is at high altitude. Most of the park is above 7,500 feet / 2,275 meters. High altitude means cooler temperatures. Yellowstone's weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s / 25° C. At night in any given month, the temperature may drop close to freezing (32° F / 0° C). So it is best to come prepared for cold evenings and mornings, especially if you are camping or hiking. When you leave your campsite, please leave it prepared for possible thundershowers and wind.

Spring Weather

Cold and snow linger into April and May, although temperatures gradually climb. Average daytime readings fall in the 40s to 50s / 5 - 15° C, reaching the 60s and 70s / 15 - 25° C by late May and June. Overnight temperatures fall below freezing and may plunge near 0° F / -20° C. These are statistical averages; actual conditions can be vastly different from long term "norms." At any time of year, be prepared for sudden changes; unpredictability, more than anything else, characterizes Yellowstone's weather. Storms in late May and early June may result in significant accumulations of snow--up to a foot of snow in 24 hours is not uncommon.

Summer Weather

Average maximum summer temperatures are usually in the 70s / 25° C and occasionally in the 80s / 30° C in the lower elevations. Nights are cool and temperatures may drop into the 30s and 40s / 0 - 10° C. Depending on the elevation, temperatures may even fall into the 20s / -5° C with a light freeze. June can be cool and rainy; July and August tend to be somewhat drier, although afternoon thundershowers and lightning storms are common. During lightning storms get off water or beaches and stay away from ridges, exposed places, and isolated trees. At any time of year, be prepared for sudden changes; unpredictability, more than anything else, characterizes Yellowstone's weather.

Fall Weather

Fall weather can be pleasant, although temperatures average 10 to 20 degrees lower than summer readings--highs in the 40s to 60s / 5 - 20° C. Over night temperatures can fall into the teens and single digits / -10° to -20° C. Snowstorms increase in frequency and intensity as the weeks go by. At any time of year be prepared for sudden changes; unpredictability, more than anything else, characterizes Yellowstone's weather.

Winter Weather

Winter temperatures often hover near 0° F / -20° C throughout the day but may reach highs in the 20s / -5° C. Subzero over night temperatures are common. Occasionally, warm "chinook" winds will push daytime temperatures into the 40s / 5 - 10° C, causing significant melting of snowpack--especially at lower elevations. Yellowstone also typically experiences periods of bitterly cold weather. The lowest temperature recorded in Yellowstone was -66° F / -54° C near West Yellowstone on 09 Feb 1933. Annual snowfall averages near 150 inches / 380 cm in most of the park. At higher elevations, 200-400 inches / 5 - 10 meters of snowfall have been recorded. At any time of year, be prepared for sudden changes; unpredictability, more than anything else, characterizes Yellowstone's weather.
