About the UV index in Guatemala City
Guatemala City sits at 14.6° N, in the northern hemisphere. Today's UV peaks at 13.3: the "extreme" band, which uvlevel.net treats as extreme danger for unprotected skin at the worst hour.
Guatemala City sits close to the equator, so the sun stays high for most of the year: UV barely dips at any point, and there's no sharply defined "season" the way there is further from the equator.
Altitude here
Guatemala City sits about 1497 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.
