Statistically, which sky condition offers superior mitigation of damaging UV radiation compared to partly cloudy conditions?

Answer

Full cloud cover (overcast)

Full cloud cover, or overcast skies, are statistically superior for UV protection because the dense moisture and particles in thicker clouds scatter and absorb more radiation than scattered or thin cloud layers.
