About the UV index in Phnom Penh
Phnom Penh sits at 11.6° N, in the northern hemisphere. Today's UV peaks at 10.2: the "very high" band, which uvlevel.net treats as serious danger for unprotected skin at the worst hour.
Phnom Penh 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.
