Why Australia and New Zealand has the highest rate of melanoma in the world?

The major modifiable risk factor for melanoma is exposure of the skin to UV radiation, with total dose determined by both ambient UV and personal behaviour. New Zealand and Australia have high levels of ambient UV radiation.

  • Australia receives much more solar radiation than California or even the Mediterranean famed for its sunny summers and beautiful beaches.

Is the sun stronger in New Zealand than Australia?

There is a strong latitudinal gradient UVI. Consequently, the mean UVI in New Zealand is significantly less than in Australia, but is about twice as much as in the UK, which spans a range of much higher latitudes.

Why is the UV so high in Australia?

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.

Why is the sun stronger 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.
