Winter in Jackson Hole can be quite variable. The snow can start flying in October and continue to May or even June. However, we typically experience the onset of winter around the end of November, when the snow starts accumulating on the ground. So it continues until the end of March, when it melts off and the ground becomes visible again. Our days are shorter during the winter and the temperature drop is noticeable as the sun goes down. We do recommend packing wool or synthetic layers for your vacation so you'll stay warm and be able to enjoy all the outdoor activities that Jackson Hole has to offer during the winter.
Average high and low temperatures for Jackson Hole are:
