The UV Index shows the intensity of the sun’s UV radiation using a scale that begins at 0 and has no upper limit. An index of 3 or above indicates that UV levels are high enough to damage skin, so sun protection is recommended.
The daily sun protection times tell you the times of the day the UV Index levels are forecast to be 3 or higher. The sun protection times vary according to your location and will change throughout the year.
In general, during summer in Australia, all states experience long periods during the day when the UV Index is 3 or above. In late autumn and winter in southern Australia, the UV Index may fall below 3 and sun protection is not necessary.
