Sichuan, China · 30.57, 104.07
Today's peak reaches moderate levels. Unprotected skin starts to redden in about 35 min at the worst hour: shade, sunglasses and SPF 30 are enough.
Chengdu sits at 30.6° N, in the northern hemisphere. Today's UV peaks at 4.8: the "moderate" band, which uvlevel.net treats as caution for unprotected skin at the worst hour.
In the Northern Hemisphere at this latitude, UV climbs highest around June and July and eases, without disappearing, around December and January. Even the winter trough here can still cross the moderate band near midday.
Chengdu sits about 484 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 4% 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.
