Is UV index higher in Australia?
Is UV index higher in Australia?
The problem with Australia is that the continent receives higher UV radiation levels than Europe. “Being located close to the ozone hole over the Antarctic means that much higher, more severe levels of UV radiation get through to ground level,” says Dr Hasanien.
Which Australian state has the highest UV?
Tasmania
In fact, some people believe the sun “bites” harder on the Apple Isle. The truth is that the whole of Australia experiences extreme ultraviolet (UV) levels in summer — including Tasmania. “The higher the sun, the higher the UV,” Vernon Carr, from the Bureau of Meteorology, said.
Why UV is high in Australia?
The planet is about 1.7% closer to the sun in January, during the southern summer, and 1.7% further away in July – northern summer. So that means when the sun is strongest the southern hemisphere is 3.4% closer to the sun than the north is during their summer. This increases UV by about 7%.
Which city in Australia has highest UV Index?
It can be seen from the data that Adelaide, Melbourne, and Canberra have the same UV indexes at 6, whereas the tropical areas such as Darwin have much higher UV indexes. The city with lowest average UV index is Hobart at 5, which is known as being a moderate level.
Does Australia have no ozone layer?
More about ozone layer depletion This includes a five to nine per cent depletion over Australia since the 1960s, which has increased the risk that Australians already face from over-exposure to UV radiation resulting from our outdoor lifestyle.
Which city in Australia has highest UV index?
Is the Australian sun stronger?
This means that the summer sun in Australia is 7 to 10 percent stronger than similar latitudes in the Northern Hemisphere.
What countries have the highest UV index?

Can you tan through a window?
Surprisingly, you CAN get a suntan through a window! Most panes of glass absorb around 97 per cent of the sun’s UVB rays – the ones which cause sunburn and some skin cancers. While the glass will absorb 37 per cent of the less harmful UVA radiation, expert Luis Villazon told Science Focus.
Where is Australia’s lowest UV?
Why is the ozone layer so low in Australia?
The stratospheric ozone layer absorbs the biologically damaging wavelengths of ultraviolet (UV) rays but in the 1970s, Australia’s ozone layer was severely thinned as a consequence of heavy use of ozone-depleting, substances such as chloroflurocarbons (CFCs) and hydro-chloroflurocarbons (HCFCs).
