Is the UV worse in New Zealand?
The sun in New Zealand is higher in UV radiation due to the ozone hole. The hole peaks in size in September, and on a sunny spring day you can get burned even though the temperature is only 15°C or so. NZ weather forecasts during summer give burn times in minutes.
Why is NZ UV so high?
That factor alone means that the southern hemisphere summer will have 7\% more UV radiation than the northern hemisphere summer. Because ozone is generated at the equator, it gets transported to higher latitudes, and that transport is more efficient in the southern hemisphere, and that factor is about a 10\% effect.
Why is the sun so bad in New Zealand?
New Zealanders are especially susceptible to sunburn. This is due to two factors of our environment: The ozone layer over New Zealand is thinner. The ozone layer’s role is to absorb the harmful UV rays that are sent from the sun.
Who has the harshest sun in the world?
The highest UVI of 25 was in the grid cell centred on Cuzco, in southern Peru (13.5° S, 3360 m a.s.l.). Peak values on the edge of the Antarctic Plateau also exceed the highest UVI in New Zealand, and are comparable to those at sea level in the tropics.
Which country has the strongest sun?
Australia – where the Sun hits the hardest
- Look at the bright red spots in the Pacific, mid-Atlantic and Australia where irradiance (the power of solar radiation) is highest.
- Australia receives much more solar radiation than California or even the Mediterranean famed for its sunny summers and beautiful beaches.
What country has the strongest UV?
New Zealand

Why does NZ have no ozone layer?
Ozone concentrations measured over New Zealand are not affected directly by the ozone hole, which lies over Antarctica each spring. The ozone hole is an area where the ozone layer is less than 220 DU, caused mostly by ozone-depleting substances emitted by people.
Which country has the lowest UV rays?
In contrast, the safest countries are found in Scandinavia, with Finland boasting the lowest average (2.17) and Sweden (2.25), Norway (2.25) and Denmark (2.67) not far behind….Revealed: The Travel Hotspots That Could Be Damaging to Your Health.

Does Australia have highest UV?
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.
Why is UV so bad 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 UV rays are high in Australia?
Does New Zealand have higher UV levels than other countries?
However, other countries in the southern hemisphere have higher UV levels than New Zealand. The following countries have higher UV levels: Peru, Bolivia, Chile and Argentina [ 3 ]. New Zealand’s high UV levels contribute to the country having one of the highest melanoma incidence rates in the world.
What is UV exposure and how does it affect us?
UV exposure can affect our health in a number of ways. Too much UV exposure can cause melanoma, non-melanoma skin cancer, and cataracts. Too little UV exposure can lead to vitamin D deficiency, which can affect bone health and immune system function. New Zealand has relatively high UV levels, and one of the highest melanoma rates in the world.
Which countries have the highest UV levels for melanoma?
The following countries have higher UV levels: Peru, Bolivia, Chile and Argentina [ 3 ]. New Zealand’s high UV levels contribute to the country having one of the highest melanoma incidence rates in the world. Read the latest statistics about melanoma on the melanoma webpage.
Why is the Sun closer to New Zealand in the summer?
This means that the sun is closer to New Zealand in our summertime than it is to northern hemisphere countries in their summertime. New Zealand has a comparatively ‘clean’ atmosphere due to its remoteness and low population density. This means that UV radiation can pass through the atmosphere relatively unhindered.
