How To Prepare for Jackson Hole Weather
- Deep-freeze winters (Dec – Feb)
Highs hover below freezing while valley inversions trap cold air overnight. Expect 5-6 decent snow days each month and steady northwest breezes around 12–15 mph. Humidity runs unusually high for the Rocky Mountains, thanks to the Snake River headwaters micro-climate.
This video from February ’25 best sums up Jackson, WY winter weather:
- Shoulder swings (Mar & Apr)
Temperatures leapfrog 20–30 °F within a day. Snow gradually trades places with cold rain; wind is still gusty. Pack everything from ski shells to rubber boots. - Mud-lovin’ May
Warm-ish afternoons (~60 °F) meet the year’s wettest month by number of rain days (≈ 9). Great for wildflowers, lousy for white suede loafers. - Blue-sky summer (Jun – Aug)
Chamber-of-commerce weather: Crisp mornings in the 40s, highs topping in the low 80s, and fewer than five wet days a month. Afternoon wind settles into a pleasant 10-13 mph west breeze, just enough to keep skeeters confused. - Golden fall (Sep & Oct)
Aspen gold arrives with cool nights and a faint uptick in moisture. First valley snowflakes often ride an early-October cold front. - Storm-building November
Clocks fall back, humidity jumps, and snow days triple relative to October. By Thanksgiving, ski wax chat replaces small talk.
Local Tips
- Altitude adds bite. Valley readings come from ~6,200 ft; Grand Teton summits run 7,000 ft higher and are 10-15 °F colder with double the wind.
- Day–night spreads are huge. A July day can hit 85 °F and still flirt with frost at dawn. Great for sleeping, terrible for leaving beer outside “just to chill.”
- Wind matters on the water. Snake River rafters should expect afternoon gusts that can turn flatwater sections into surprise workouts.
Remember, in Jackson Hole, “four-season wardrobe” really means all four seasons in the same week, possibly the same day.
