The UV index in Jackson Hole, USA can vary dramatically through the day, especially in summer or at high latitude. This page shows today's UV index hour-by-hour, calls out the peak UV time, and tells you how strong sun protection needs to be at each hour. We use the World Health Organization UV index scale (0–11+) so values are directly comparable to UV forecasts you might see in apps or on the news. The page also shows tomorrow and the rest of the week, so you can plan beach days, hikes, sightseeing or sports in Jackson Hole around safer UV windows. Sun safety advice is tailored to the actual UV reading: at low UV you need little protection, while at very high UV in Jackson Hole you should reduce time outdoors during peak hours. This is especially relevant for fair-skinned visitors and for outdoor activities at altitude.
