Frequently asked questions
- When does West Harbour need sun protection?
- Whenever the UV index is 3 or above. In West Harbour that is typically from September through April, and any other day UV reaches 3. SunSmart NZ and NIWA use the same UV Index scale as Australia.
- Does West Harbour need sun protection in winter?
- Not every day. Midwinter middays in West Harbour often sit below UV 3, but clear late-winter days (from August in much of Auckland) cross the threshold before the weather feels like spring. Check the live index.
- Does the water make UV worse in West Harbour?
- 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.
