Today's peak is very high. Skin damage happens fast: roughly 18 min before burning at the worst hour. Avoid direct sun entirely inside the danger window below.
Las Vegas sits at 36.2° N, in the northern hemisphere. Today's UV peaks at 9.3: the "very high" band, which uvlevel.net treats as serious danger for unprotected skin at the worst hour.
Las Vegas sees the widest UV swing of the year of any latitude band: a sharp summer peak around June and July, and a winter trough around December and January where midday UV can sit near zero for weeks at a time.
Las Vegas sits about 615 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 5% to the modelled index here: uv = max(weather, CAMS) × (1 + 0.08 × metres/1000). That correction is already folded into every number on this page.
