Yellowstone Weather
Yellowstone National Park is at lofty height. Height. Most of the park is above2,275meters.
Yellowstone’s weather is unpredictable. In summer, it may be warm and sunny with temperatures in the high 70s. At night in any given month, the temperature may drop close to freezing. 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 thundershower and wind.
A sunny warm day may become fiercely stormy with wind, rain, sleet and sometimes snow. Without enough clothing, an easy day hike or boat trip can turn into a battle for survival.
