Does Carrum need sun protection in winter?

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

Does the water make UV worse in Carrum?

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.

Q: When does Carrum need sun protection?

Whenever the UV index is 3 or above. In Carrum that is typically from October through March, and any spring or autumn day UV reaches 3. SunSmart and ARPANSA use the same rule Australia-wide.

Carrum sits on the Victoria coast at 38.1°S, where sand and water bounce extra UV onto uncovered skin. Sea breeze cools the air, not the ultraviolet: summer middays here typically reach 8–11 (very high to extreme). This is cool-temperate Australia: summer UV still climbs into the very high and extreme bands, and spring arrives earlier than the air temperature admits.
