Why is the UV so high in Sydney?
During summer, the Earth’s orbit brings Australia closer to the sun (as compared to Europe during its summer), resulting in an additional 7% solar UV intensity. Coupled with our clearer atmospheric conditions, this means that Australians are exposed to up to 15% more UV than Europeans.
Which state in Australia has the highest UV index?
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 is the UV so high in Australia?
Australia’s unusually harsh sunshine results mainly from its location in the Southern Hemisphere. The elliptical orbit of the Earth places the Southern Hemisphere closer to the sun during its summer months than the Northern Hemisphere during its summer.
What is a safe UV level?
UVI 1-2 is low, which generally means it’s safe to be outdoors unprotected. Other classifications are moderate (3-5), high (6-7), very high (8-10) and extreme (11+). To some extent, the moderate to very high labels tell us little except that UV intensity is increasing.
Why is there no ozone layer over Australia?
The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. Data collected in the upper atmosphere have shown that there has been a general thinning of the ozone layer over most of the globe.
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.
Where is the lowest UV in Australia?
Is UV index higher in Australia?
Australia has some of the highest levels of UV radiation in the world – in fact, UV radiation is strong enough to cause sunburn in as little as 11 minutes on a fine summer day. UV radiation from the sun is also one of the best natural sources for vitamin D so a balance is important.
Can you get tan with a UV of 6?
It is important to remember that, in practice, no UV index is truly good for tanning. The NHS warns that a “healthy tan” does not really exist, spending long periods of time in direct sunlight is not recommended, no matter the UV index value, as any tan can increase the risk of developing skin cancer.
