Packing for Jackson Hole can be complicated considering that summer days can be 80 F during the day and dip into the low 40s at night. Winter days can be many — many — degrees below zero on the valley floor, but 25 F halfway up the mountain at Jackson Hole Mountain Resort. Temperature inversions in the winter are not at all uncommon.
Year round, the key to navigating these temperature extremes is layer, layer, layer. It’s just the layers’ thickness that varies depending on the month. A warm down — or synthetic down — jacket is a good thing to have year round, as absurd as it sounds.
Although Jackson Hole has plenty of fancy restaurants and hotels, jeans are acceptable to wear anywhere in the valley. If you mention a tie, it had better be in reference to fly-fishing. Because of the high altitude, hats and sunscreen are recommended no matter what month you are visiting.
