Jalisco, Mexico · 20.66, -103.35
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.
Guadalajara sits at 20.7° N, in the northern hemisphere. Today's UV peaks at 9.2: the "very high" band, which uvlevel.net treats as serious 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.
Guadalajara sits about 1542 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 12% 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.
