About the UV index in Chennai

Chennai sits at 13.1° N, in the northern hemisphere. Today's UV peaks at 8.6: the "very high" band, which uvlevel.net treats as serious danger for unprotected skin at the worst hour.

Chennai 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.
