Does Ironstone need sun protection in winter?

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

Does the water make UV worse in Ironstone?

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.
