When does Newcastle need sun protection?

Whenever the UV index is 3 or above. In Newcastle that is typically from September through April, and any other day UV reaches 3. SunSmart and ARPANSA use the same rule Australia-wide.

Does Newcastle need sun protection in winter?

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

Does the water make UV worse in Newcastle?

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.
