Today's peak reaches moderate levels. Unprotected skin starts to redden in about 32 min at the worst hour: shade, sunglasses and SPF 30 are enough.
Tehran sits at 35.7° N, in the northern hemisphere. Today's UV peaks at 5.1: the "moderate" band, which uvlevel.net treats as caution for unprotected skin at the worst hour.
Tehran 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.
Tehran sits about 1177 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 9% 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.
