Best time for good weather
The best time for good weather in Yellowstone National Park is during July and August.
Due to its geographical location and elevation, summers in Yellowstone are pleasant, with average daytime temperatures hovering around 70ºF and cool nighttime temperatures dropping into the 50s.
This makes the summertime ideal for sleeping outside. Temperatures can be significantly cooler at higher elevations, even dropping below freezing during the summer.
Weather during other months of the year can be much less predictable. Fall and spring can see dramatic changes in temperature while winters can be harsh with sub-zero temperatures.
Best time for camping
The best time to camp in Yellowstone National Park is during the month of September.
Summer temperatures still linger in September and most of the park’s campgrounds are still open. Crowds have thinned with the arrival of the start of the school year, making it easier to get reservations to some of the park’s coveted campgrounds.
In comparison, during the summer reservations should be made well in advance as campgrounds fill up quickly. Yellowstone closes most of its campgrounds for the season by the end of September with the exception of Mammoth, which is open year-round.

Best time to avoid crowds
September and May offer the best times to avoid crowds.
After Labor Day, crowds thin considerably in the park and don’t return to their peak levels until after Memorial Day.
During May and September, the weather is warm enough to be comfortable. And most of the park’s facilities are open during these months, allowing you to experience its best attractions. You do still need to be on the lookout for sudden changes in temperature, so make sure to layer and have rain gear with you wherever you go.

Best time to see wildlife
The best time to see wildlife in Yellowstone National Park is early spring and winter.
It really depends on what you want to see.
Early spring and fall are the best times to see bears as they’ll be foraging for hibernation during the fall and emerging from their winter slumber in the spring.
Wintertime is the best season to find wolves and bighorn sheep while other animals, such as Elk and bison, can best be spotted during the summer and fall months as they make their migrations to lower elevations for the winter.
Whichever time you choose, make sure to follow park regulations and maintain a safe distance while observing these animals.
Best time for biking
The best time for biking in Yellowstone National Park is fall and spring.
Though cycling is allowed year-round, the best season begins in early November when the park closes the roads to traffic in preparation for the coming snows. Once the snow arrives, the cycling ends.
Biking opens up again in early April when the roads clear, allowing for traffic-free cycling until about mid-May. This gives cyclists access to some 250 miles of park roads without having to share it with traffic.
Make sure the roads are clear before heading out. Check the park’s Website for road closing information.
Best time for fishing
The best time for fishing in Yellowstone National Park is July to August.
This is when the insect population is at its highest, so fish are especially active. It’s an excellent time for fly fishing on all of the park’s rivers.
Mid Summer is also the most comfortable time to fish, with warmer weather and warmer waters, making backcountry fishing a great option.
The top places to fish in the park at this time are Slough Creek, Soda Butte, and Lamar, for both their fish populations and amazing scenery.
Best time for winter sports
The best time for snow sports in Yellowstone National Park is January.
This is because the park records an annual average of 35″ of snow during the month, which is the highest of any month during the year.
This makes it an excellent time for snowmobiling, cross country skiing, snowshoeing, and other winter sports. There are numerous outfitters around the park for renting equipment or booking guided tours.
If you plan on visiting the park during the winter, make sure to come prepared with winter clothing as winter weather can be extreme in Yellowstone.
