UV index in Streaky Bay today
Streaky Bay sits on the South Australia coast at 32.8°S, where sand and water bounce extra UV onto uncovered skin. Sea breeze cools the air, not the ultraviolet: summer middays here typically reach 10–12 (very high to extreme). This is warm-temperate Australia: a long protection season from early spring through autumn, with the odd clear winter midday that still burns.

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