Does Mataura Island need sun protection in winter?

Does the water make UV worse in Mataura Island?

It can. Sand and water reflect ultraviolet, so skin that is not covered (including under the chin and on the tops of feet) picks up extra dose on top of the direct sun. The live UV index on this page is the sky reading; reflection is on top of that.
