Frequently asked questions
- When does Wirraminna need sun protection?
- Whenever the UV index is 3 or above. In Wirraminna that is typically from September through April, and any other day UV reaches 3. SunSmart and ARPANSA use the same rule Australia-wide.
- Does Wirraminna need sun protection in winter?
- Not every day. Midwinter middays in Wirraminna 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.
- Is UV worse in dry inland Wirraminna?
- Often the dose is higher than a coastal day at the same index, because there is so little shade or haze. At 31.0°S the sky is frequently clear, so the live reading on this page is what you get — not a filtered version.
