Jackson Hole is a valley in which  four tiny towns  (Wilson, Moose, Kelly and Moran)  reside and one small town (Jackson) plus one incredible National Park, the Grand Teton.  Yellowstone National Park is also nearby to the north. 

JH's longest season is winter. The mountains are cloaked in snow beginning in October or November through April. In town, however, snowfall accumulates from a few inches to a foot or two, but usually not to extreme proportions.

Temperatures can dip below zero degrees Fahrenheit in December and January. During the colder half of the year, blizzards tend to alternate with sunny (bluebird) days, but it always gets colder at night. If you visit during the winter for a ski jackson hole trip, don't be discouraged by cold temperatures. From snowshoeing, cross-country skiing, ice-skating and wooded sleigh rides to big-mountain snowboarding, skiing, snowmobiling and excursions into the backcountry - there is something for every outdoor enthusiast, or for those simply  looking for a more active vacation. But always be sure to layer up, especially in the eves when temperatures dip significantly.

It’s important to stay updated on weather conditions throughout the year, but especially during the winter, when large snowstorms can cause roads to close. Check Jackson’s one-week weather forecast as often as you can (83001). Usually any major warnings will be posted all around town, but it’s still wise to be vigilant so that you don’t wind up stranded somewhere during a storm.

Spring and summer daytime temperatures reach between 80 to 90 Fahrenheit, but nights are still relatively cool. The dry mountain climate means enjoyable, humidity-free warmth and refreshing, brisk evening temperatures usually in the 50s or 60s.The natural beauty of Jackson Hole is stunning. The Teton Mountain Range seems to breathe with majesty and power. Visiting from late Nov. to early April is reccomended to catch the splendor and solitude of JH's winters. Visit between June and early September to hike in lush mountainous trails beneath constant clear blue skies.
