Idaho Falls in February
Not the best time
Still deep winter territory. The only reason to come now is if you're getting a killer deal on accommodations or you genuinely enjoy sub-arctic conditions.
Weather
February stays frozen solid with occasional snowstorms rolling through the valley. The days get slightly longer but don't expect much relief from the cold. Wind chill can make those already low temps feel downright dangerous.

All Months
Summer is Idaho Falls' sweet spot. June through September brings warm days, minimal rain, and full access to outdoor activities. July and August see temperatures in the 80s with cool evenings perfect for riverside walks. This is also peak season for Yellowstone access, though you'll share the roads with plenty of other visitors.
September might be the secret best month. Crowds thin out, temperatures stay comfortable in the 70s, and fall colors start showing in the surrounding mountains. Hotel rates drop 20-30% after Labor Day.
Winter transforms the area into a snow sports playground. Kelly Canyon Ski Area, 30 minutes northeast, offers affordable skiing with lift tickets around $45. The city itself stays relatively mild thanks to the river, but pack layers - morning temps can hit single digits while afternoons warm to the 30s.
Avoid late March through early May unless you enjoy mud season. Snowmelt creates soggy conditions, many trails remain inaccessible, and it's too early for most summer activities but too late for winter sports.
