Kenya · -1.29, 36.82
Today's peak is extreme. Unprotected skin burns in about 11 min at the worst hour. Treat the sun as a hazard: stay indoors or fully covered.
Nairobi sits at 1.3° S, in the southern hemisphere. Today's UV peaks at 15.4: the "extreme" band, which uvlevel.net treats as extreme danger for unprotected skin at the worst hour.
Nairobi 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.
Nairobi sits about 1668 m above sea level. Thinner air scatters and absorbs less UV on the way down, so uvlevel.net adds roughly 13% 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.
