Fall in Jackson Hole rewards travelers with golden aspens, crisp mountain air, and plenty of room to explore. It can also bring several kinds of weather in a single day. A sunny afternoon may feel warm, while mornings, evenings, and higher elevations can be much cooler.
That variety is part of what makes the season so memorable. The key is packing versatile layers that let you comfortably move between a morning wildlife tour, an afternoon hike, and dinner in town.
This Jackson Hole fall packing guide covers the clothing, footwear, and essentials worth bringing for a September or October trip.

What Is the Weather Like in Jackson Hole During Fall?
September often brings sunny afternoons and cool mornings, with colder conditions becoming more common as October approaches. According to the National Park Service, historical averages at Moose, Wyoming, include September highs around 69°F and lows around 32°F. October averages are approximately 56°F during the day and 23°F at night.
These are seasonal averages, not a trip-specific forecast, so checking conditions shortly before departure is always helpful.
Sun, rain, and occasional snow are all possible during fall. Conditions may also feel different in town than they do beside an alpine lake or on a higher-elevation trail. Packing in layers makes it easy to adjust throughout the day without bringing a separate outfit for every activity. Review Grand Teton National Park weather information while preparing for your trip.
Start With Versatile Layers
A dependable fall outfit in Jackson Hole begins with three simple layers:
- A lightweight base layer: Choose a breathable shirt that works on its own during warmer afternoons.
- A warm mid-layer: Bring a fleece, sweater, or light insulated jacket for cool mornings and shaded trails.
- A weather-resistant outer layer: A packable rain jacket or shell adds protection when wind, rain, or early snow moves through the valley.
This combination is useful well beyond the trail. You can remove a layer while walking around Town Square, then add it again for sunset or an outdoor dinner.
Clothing to Add to Your Suitcase
- Comfortable long-sleeve shirts
- T-shirts for layering
- A fleece, sweater, or lightweight puffer
- A waterproof or water-resistant jacket
- Jeans or casual pants
- Hiking pants or athletic leggings
- Warm socks
- Sleepwear suited to cooler nights
- A hat and light gloves, especially for October visits
A heavier winter coat is not always necessary in early fall, but a warm jacket becomes increasingly useful later in the season. Review the forecast for your exact dates before deciding.
Pack Footwear for the Day You Have Planned
Bring comfortable walking shoes for shopping, dining, and exploring downtown Jackson. If hiking is on the itinerary, choose hiking shoes or boots with reliable traction. Trails can be dusty and dry one day, then muddy, frosty, or lightly snow-covered the next.
Water-resistant footwear is especially useful in October or during trips that include early-morning excursions. Pack a second pair of shoes for evenings so you can leave wet or muddy hiking footwear by the door.
- Walking shoes or casual sneakers
- Hiking shoes or boots with good traction
- Warm hiking socks
- Casual boots or clean shoes for dinner
What to Pack for Fall Hiking
Cooler temperatures can make fall a beautiful time to explore Jackson Hole on foot. Along with layers and sturdy footwear, pack a small daypack with:
- A reusable water bottle
- High-energy snacks
- Sunscreen and sunglasses
- Lip balm
- A brimmed hat
- A paper or downloaded trail map
- A portable phone charger
- A basic first-aid kit
- An extra layer
- Bear spray that you know how to carry and use
Bear spray cannot be carried on commercial flights, so plan to purchase or rent it after arriving. Always check current trail conditions and wildlife closures before heading out.
Grand Teton National Park also recommends taking water, extra clothing, and a map when hiking. Review the park's current safety guidance before exploring.
Do Not Forget Sun Protection
Cool air can make it easy to underestimate the mountain sun. Jackson Hole sits at a high elevation, and many popular activities provide little shade. Sunscreen, sunglasses, and a hat belong in your day bag even when the forecast looks cool or cloudy.
A reusable water bottle is equally important. Dry mountain air and active days can leave you needing more water than expected.
Bring a Few Wildlife-Watching Essentials
Fall is an exciting time to look for wildlife around Jackson Hole and Grand Teton National Park. A few compact items can make those early mornings even better:
- Binoculars
- A camera with a zoom lens
- A warm hat and gloves
- A thermos or reusable coffee cup
- A small blanket for the car
Use binoculars or a zoom lens instead of approaching an animal. The National Park Service requires visitors to remain at least 100 yards from bears and wolves and at least 25 yards from other wildlife.
What to Wear Around Town
Jackson Hole style is relaxed, practical, and mountain-inspired. Jeans, sweaters, boots, and casual jackets work well at most restaurants and shops. Even upscale dinners rarely require formal clothing, so there is no need to devote much suitcase space to dressy outfits.
Pack one polished but comfortable look for a special dinner, then rely on pieces you can mix and match for the rest of the trip. A sweater or light jacket is useful when walking back to your rental after sunset.
Useful Extras for a Fall Trip
- A compact umbrella
- A small backpack or crossbody bag
- Moisturizer and lip balm
- Reusable shopping bags
- A portable charger
- Downloaded maps and reservation confirmations
- A swimsuit for your rental's hot tub or shared pool
- A laundry bag for dusty or muddy clothing
If you are planning to photograph the fall colors, bring spare batteries or a charging bank. Cold mornings can drain batteries more quickly, and you may spend longer outside once the Tetons light up.
