Frequently asked questions

When does Whyalla Stuart need sun protection?
Whenever the UV index is 3 or above. In Whyalla Stuart that is typically from September through April, and any other day UV reaches 3. SunSmart and ARPANSA use the same rule Australia-wide.
Does Whyalla Stuart need sun protection in winter?
Not every day. Midwinter middays in Whyalla Stuart 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 beach make UV worse in Whyalla Stuart?
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.
