Jackson Hole is one of the top fly fishing destinations in the American West, known for its wild cutthroat trout, legendary rivers, and diverse fishing experiences. Whether you’re casting from a drift boat, hiking into the back country, or wading into a stream, any angler would want to know when the best time to visit is.
Below is an easy month-by-month breakdown of what to expect, from early spring through late fall, to help you plan the perfect Jackson Hole fishing adventure.
Fishing in Jackson Hole: Season by Season
Spring (April–May)
Spring brings cold mornings, warming afternoons, and the first big bug activity as fish wake up after winter.
What to expect:
Colder temps early in the season
Limited access due to lingering snow
Best action during the warmest hours of the day
First major hatches of the year (midges + early mayflies)
Spring highlights:
April 1: unofficial kickoff to the season
Pre-runoff Snake River: local favorite for early-season action
May runoff: rivers rise and turn silty
Lakes begin to thaw: great option when rivers are high
Firehole River (Yellowstone): opens Memorial Day weekend and fishes exceptionally well
Spring is a great choice for anglers looking for fewer crowds, early hatches, and the chance to chase trout before the rush of summer.
Summer (June–August)
Summer is the most popular time to fly fish in Jackson Hole, and for good reason.
June (Runoff Peak):
High, fast water across many drainages
Excellent lake fishing
Smaller tributaries shine during this time
Walk-and-wade anglers can find pockets of slower water
Late June–July:
Snake River usually clears by late June
By July, nearly every river in the region is fishable
Prime time for dry fly fishing
Summer highlights:
Diverse hatches including mayflies, stoneflies, caddis, and terrestrials
Cutthroat trout move back into the Snake River
Fish are aggressive and hungry after returning from tributaries
If you love dry flies, long sunny days, and big-water drift boat fishing, July and August are exceptional.
Fall (September–October)
Fall is an angler favorite, and arguably the most underrated time to fish in Jackson Hole.
What to expect:
Cooler temperatures and crisp mornings
Stunning fall colors across Jackson Hole and Grand Teton National Park
Lower, clearer water
Trout feeding aggressively to prepare for winter
Fewer crowds on the rivers
By early October, water levels drop to winter flows, concentrating fish and making them easier to locate. Weather can be unpredictable, so packing layers is key.
