Do you want to visit Yellowstone National Park with pleasant temperatures? Then the months of June to September are the best time to visit Yellowstone National Park. Although a (nighttime) snow shower cannot be completely ruled out at the beginning of June, in these months you are most treated to quite a large number of hours of sunshine and a daytime temperature of about 20°C.
Especially in July and August, when the weather and climate in Yellowstone is most pleasant, many people travel to Yellowstone. The chance of park closures is then the smallest. It can be a bit busy during this period so it is recommended to book a place to stay in advance.
During the months of July and August you are most likely to experience good weather with pleasant average temperatures that fall between 20°C and 26°C.
