Weather by month
Jackson Hole
Wyoming
A high valley that pools cold air like a bowl: deep reliable winters, a short green summer, and shoulder seasons where half the town simply closes.
The best time to come
July through September is the summer window, with the Tetons at their most cooperative and September thinning the crowds without giving up the warmth. Ski season peaks January through March; the weeks on either side of both windows are genuinely dead here, and nobody pretends otherwise.
