Where Is The Strongest Uv In The World?

Chile’s northern Atacama Desert has been pointed out as one of the places on earth where the world’s highest surface ultraviolet (UV) may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low total ozone column.

What is the strongest UV index?

UV Index Scale

• 0 to 2: Low. A UV Index reading of 0 to 2 means low danger from the sun’s UV rays for the average person.
• 3 to 5: Moderate. A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure.
• 6 to 7: High.
• 8 to 10: Very High.
• 11 or more: Extreme.

Are UV rays stronger in different countries?

UV levels are higher closer to the equator. Closer to the equator the sun’s rays have a shorter distance to travel through the atmosphere and therefore less of the harmful UV radiation can be absorbed.

At what UV can you burn?

The higher the value, the greater the risk of sunburn and the less time it takes to damage your skin. When the UV Index is 3 or more, the sun is strong enough to cause damage for some skin types so take care and protect your skin, especially if you burn easily.

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.

Why is UV so strong 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.

Why is UV stronger 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.

What country has the most intense sun?

Altogether 90 percent of the daylight in Yuma is sunny. Year round, Yuma averages 11 hours of sun a day. Yuma’s sunniest month is June, when it’s sunny for 97 percent of the time between sunrise to sunset.
10 Sunniest Countries on Earth.

Can you get burned in 1 UV?

The ultraviolet levels are measured on a daily basis by the National Weather Service and then are converted to a scale of exposure risks. A UV Index reading two or lower means there is a minimal risk of sunburn for the average person.

Do clouds block UV rays?

While clouds do reduce some of the sun’s UV rays, they don’t block all of them, as the Skin Cancer Foundation explains. UVA rays can penetrate clouds, and they can also reach below the water’s surface.

Do black people get sunburned?

Health experts advise everyone, regardless of skin color, to use sunscreen with an SPF of at least 30. Although dark-skinned people won’t get sunburned as quickly, they will still burn and are still susceptible to sun-induced damage—such as sun spots and wrinkles—and cancer .

Why UV rays are high in USA?

Specifically, they saw increases in the southern and western U.S., which was most likely due to higher altitudes. Generally, UV radiation levels are higher at higher altitudes as the air is thinner, dryer, and cleaner and has less scattering and absorption of UV.

Is the sun stronger in Europe?

You hear people say it often – “Aussie sun is different from Europe’s.” However, the sun itself always has the same strength, regardless of the continent.

Why is New Zealand sun so strong?

At mid-latitudes, such as New Zealand, it is thickest during spring and thinnest during autumn. This means the ozone layer over New Zealand thins during summer, providing less protection from UV sunlight when we are closest to the sun and the sun is highest in the sky.

Is UV stronger in UK?

6) It’s possible to measure UV
The UV Index indicates the degree of risk of sunburn and runs from 1-20. The highest level recorded in the UK is usually 8, but only in Southern England. In sunnier climates, the UV Index may be much higher than experienced in the UK, even if the temperature is relatively low.

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.

Is the ozone hole over Australia?

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.

Why is Australia sky so blue?

Sometimes, in Australia’s outback the sky is very blue because it’s so dry, but on other days when it’s dusty or during bushfires, the sky will appear much redder. The blueness of the sky is also affected by other factors, such as the moisture and particulate matter in the air.

Is the sun stronger than 30 years ago?

NASA – UV Exposure Has Increased Over the Last 30 Years, but Stabilized Since the Mid-1990s.

Are UV rays stronger in Ireland?

The time of day: UV rays are stronger in Ireland from 11 am to 3 pm. The time of year: UV rays reach the earth all year round but in Ireland exposure is usually greatest from April to September. Altitude: The higher up you go the higher the level of UV radiation.

Which country has full sun?

Norway is known as the land of midnight sun. Due to Norway’s high altitude, there are seasonal variations in daylight because of the period of refracted sunlight is long. In this country, for about a period of 76 days from late May to late July, the sun never sets for about 20 hours.
