Today's peak stays low. Unprotected skin is not at meaningful risk at any point in the day.
Ulaanbaatar sits at 47.9° N, in the northern hemisphere. Today's UV peaks at 1.4: the "low" band, which uvlevel.net treats as no danger for unprotected skin at the worst hour.
Ulaanbaatar 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.
Ulaanbaatar sits about 1290 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 10% 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.
