Best Time to Visit Yellowstone
Summer (June–August): warm and busy
Summer is the obvious choice. Daytime temps are 70–80F, all roads are open, and Old Faithful erupts on schedule. The geyser basins are accessible and predictable. The downside: everyone else is here too. The most popular tours book 3–7 days ahead, and parking at Old Faithful and the Canyon can be tight mid-day. Sunrise and sunset have the best light for photography and the fewest crowds — most tour groups are moving mid-morning to early afternoon.
Shoulder seasons (May, September): the sweet spot for local knowledge
May and early September are excellent if you can swing it. The park is warming up (May is cooler; September is still warm), crowds are lighter, and wildlife is more active in the cooler weather. You need a light jacket or layers, but the geyser basins are fully open. Roads may still have patches of snow at higher elevations in early May, but the main loops are clear. Tours still run and book less frantically. If you prefer quiet mornings without a hundred people at the Old Faithful overlook, book shoulder season.
Winter (October–April): snowcoach and snowmobile only
Winter is stunning but requires planning. The interior of the park closes to regular cars — the roads are not plowed for public driving. The only way into the interior is a guided snowcoach or snowmobile tour. The park is quiet, the geothermal features steam more dramatically against the snow, and wolves and elk are visible in the snow. But it is cold (often well below freezing), daylight is short, and tour availability is limited. If you are interested in winter, book a dedicated winter tour operator or inquire with your preferred guide about snowcoach options.
Spring (April) and fall (October): variable and cool
Spring (April) and early fall (October) are transitional. Roads are opening or closing, weather is unpredictable, and you need layers. May and September are much better for shoulder-season visiting than April or October. If you are stuck with April or October, expect cool mornings (40–50F), possible rain or even snow at higher elevations, and smaller crowds. Pack a fleece, a rain jacket, and waterproof shoes.
Summer is warm and safe but crowded. Shoulder seasons (May, September) have lighter crowds and excellent weather. Winter is spectacular but requires a guided snowcoach — no self-driving the interior.
Crowds and timing
Park visitation in 2023 was about 4.5 million visitors. The vast majority come June through August. If you want solitude, visit May or early September. If you want warm weather and do not mind crowds, June–August is fine — just book ahead and expect popular tours to fill 3–7 days prior.
Frequently asked questions
When is the best time to visit Yellowstone?
Summer (June–August) is warm and all roads are open. Shoulder seasons (May, September) have lighter crowds and excellent weather. Winter is spectacular but interior roads close to regular cars — you must take a guided snowcoach or snowmobile.
Is June or July better than August?
All three are warm (70–80F) and fully open. June and early July have slightly fewer people than late July and August. For photography, sunrise and sunset have the best light and fewer crowds than mid-day.
What about winter tours?
Winter is strikingly beautiful — geysers steam more against snow, elk and wolves are visible — but interior roads close to regular cars. You need a guided snowcoach or snowmobile tour. Daylight is short and it is cold, so book with an operator that specializes in winter.
Do I need layers in shoulder season?
Yes. May and September are good weather but cooler than summer. Bring a light fleece or jacket. Early morning and evening can be chilly even in September. Fall (October) and spring (April) are worse — plan for 40–50F and possible rain.
