Yellowstone’s vast landscapes and geothermal features are matched only by the unpredictability of its weather. Spanning three states, Yellowstone experiences rapid temperature fluctuations and sudden snowstorms, even in late spring. Visitors may find themselves basking in sunshine one moment and reaching for their parkas the next. The park’s high elevation and mountainous terrain contribute to its erratic weather, making it essential for visitors to check forecasts frequently and pack accordingly.
