Mexico City, Mexico · 19.43, -99.13
Today's peak is extreme. Unprotected skin burns in about 14 min at the worst hour. Treat the sun as a hazard: stay indoors or fully covered.
Mexico City sits at 19.4° N, in the northern hemisphere. Today's UV peaks at 12.1: the "extreme" band, which uvlevel.net treats as extreme danger 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.
Mexico City sits about 2238 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 18% 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.
