Australian UV-Index Models

The graph displays the monthly average UV-Index value that can be expected at solar noon (when the sun is highest in the sky) at this location. On the graph, each month is shown as two two-week blocks. The actual values could be slightly higher or lower than the averaged model depending on ozone levels and atmospheric conditions, particularly cloud cover.

	3 to 5	Moderate	Wear sun protective clothing, a hat, sunscreen, sunglasses and seek shady areas.
	6 to 7	High	As above.
