Jackson Hole Weather

In a place where it could snow any day of the year, it’s best to go out prepared with clothing and by keeping a close eye on the forecast. 

Summer (July and August) Warm days and cool nights prevail, with afternoon thundershowers being common.  The snow level gradually retreats, with divides between the mountain canyons free of snow by August.  

As the valley wildflowers fade, canyon and alpine wildflowers peak. Temps do swing high and low, with a chance of passing storms but a thorough list from the Jackon Hole Chamber is a great place to start with  Pack Like an Expert for Your Summer Visit to Jackson Hole. Coming out for Labor Day weekend? We've made Your Guide to Labor Day Weekend in Jackson Hole too! 

Sunny days and cold nights alternate with rain and snowstorms in the Fall (September-November) but the colorful changes in the landscape and early season snowfalls make the quaking Aspens and turning cottonwoods enough reason to visit all on their own. Depending on moisture, fall colors tend to peak in late September and early October.  As snow becomes persistent by late fall, elk move to wintering areas at lower elevations. A locals' favorite at this time of year is the Jackson Hole Fall Arts Festival. Widely recognized as one of the premier cultural events in the Rocky Mountain West, the art extravaganza embraces the change of seasons entirely with artists painting the outdoors, well, outdoors!

Spring (late April - June) offers up mild days and cold nights interspersed with rain and occasional snow.  Valley lakes usually thaw by late May depending on snow-pack with snow levels remaining just above the valley elevations until mid-June.  

Valley wildflowers begin blooming as the snow melts peaking in June and July. Spring is easily the most under-rated season in Jackson Hole. There is so much to do as the animals wake up from the winter conditions. It’s also the peak of run-off for white water enthusiasts. Check out our itineraries for The Adventurer, The Foodie, and The Family.

Late November  through April, makes up Winter, though sometimes the season stretches in either direction.  Snow blankets the mountains and the valley, with accumulations of ten feet common in the mountains and two to five feet in the valley.  

Between storms, sunny days and frigid nights provide perfect conditions for winter photography, wildlife viewing, snowshoeing, as well as downhill and cross-country skiing. Our friends at Happy Active Family share insider tips as to Six Ways to Spend the Weekend Outside this Winter that are not downhill skiing.
