Frequently asked questions

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