Federal District, Brazil · -15.79, -47.88
Today's peak is extreme. Unprotected skin burns in about 12 min at the worst hour. Treat the sun as a hazard: stay indoors or fully covered.
Brasília sits at 15.8° S, in the southern hemisphere. Today's UV peaks at 13.9: the "extreme" band, which uvlevel.net treats as extreme danger for unprotected skin at the worst hour.
In the Southern Hemisphere at this latitude, UV climbs highest around December and January and eases, without disappearing, around June and July. Even the winter trough here can still cross the moderate band near midday.
Brasília sits about 1085 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.
