When does Nelson need sun protection?

Whenever the UV index is 3 or above. In Nelson that is typically from October through March, and any spring or autumn day UV reaches 3. SunSmart NZ and NIWA use the same UV Index scale as Australia.

Does Nelson need sun protection in winter?

Not every day. Midwinter middays in Nelson often sit below UV 3, but clear late-winter days (from August in much of Nelson) cross the threshold before the weather feels like spring. Check the live index.

Does the water make UV worse in Nelson?

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.
