Yellowstone National Park – Best time to go

Best time to visit Yellowstone National Park

Yellowstone National Park and the wider state of Wyoming receives a seasonal but generally dry, climate. The summer months of May to September consist of highs of 19–28°C while November to March temperatures may range between 3–8°C during the daytime and may dip as low as -10°C at night.  Depending on what activities you want to do and what you are wanting to see within the park will determine the best time of year for you. 

Favourite Season

Although July and August are when the weather warms up and hiking, camping, and wildlife viewing become popular; this is also the parks busiest so we love June and September. 

Best times to visit

Spring Season

Early spring sees Yellowstone still covered by snow and cold, wet days prevail. By late May to June the park’s interior roads begin to open and the park begins to awaken, although you may still see wintery days. 

Summer Season

Summer is when Yellowstone really kicks into gear. Nights still tend to be cool and can drop below freezing in higher elevation; daily temperatures often reach the 30s, however thunderstorms are common in the afternoon. 

Autumn Season

Weather in Yellowstone National Park is unpredictable throughout the year but particularly so in autumn. Temperatures can range from freezing to mild and snow can unexpectedly fall. 

Winter Season

Winter in Yellowstone is cold and snowy, with landscapes punctuated by steaming geyser basins and winter wildlife. Temperatures are usually below freezing and snow falls regularly, especially at higher elevations.
