Map of peak UVI, using a modified colour scale to highlight the absolute peaks. Figure 2 uses a modified colour scale and shows that the highest values of UVI occur in the Peruvian Andes and throughout the Altiplano region. The maximum UVI of 25 is for the grid cell at 13.5° S, 172° W, centred on Cuzco in Peru.

Where is the UV index highest in the US?
The southern states, California, and especially Hawaii, are closest to the equator and tend to have a higher UV Index. States at a high altitude, such as Utah and Colorado, also tend to have a relatively high UV Index.
What is the highest possible UV index?
11
The UV Index was previously reported on a scale of 0 to 10+, with 0 representing “Minimal” and 10+ representing “Very High.” As of May 2004, EPA and NWS will report the Global Solar UV Index using a scale of 1 (or “Low”) to 11 and higher (or “Extreme”).
What country has lowest UV?
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 Australia sun so strong?
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. This means that the summer sun in Australia is 7 to 10 percent stronger than similar latitudes in the Northern Hemisphere.
What state has the strongest sun?
The sunniest state of all: Arizona
Phoenix, Tucson, and Flagstaff are all in the top 25 sunniest cities in the US, and Phoenix ranks #1 with an annual sunshine rate of 85.8%.
Is the sun stronger in Mexico?
The Mexico sun is direct, intense, and penetrates the atmosphere easily. Take “practice runs” by tanning for short spurts of time before you travel. Gradual exposure to the sun can prevent a painful sunburn on your vacation.
What states have the strongest sun?
The sunniest U.S. states are: Arizona (5,755 kJ/m^2), New Mexico (5,642 kJ/m^2), Nevada (5,296kJ/m^2), Texas (5,137 kJ/m^2), California (5,050 kJ/m^2), Colorado (4,960 kJ/m^2), Oklahoma (4,912 kJ/m^2), Kansas (4,890 kJ/m^2), Utah (4,887 kJ/m^2), and Florida (4,859 kJ/m^2).
At what UV do you tan?
TABLE 1. MINUTES OF SUNLIGHT EXPOSURE FOR SUFFICIENT VITAMIN D
| SKIN REACTION TO SUNLIGHT | UV Index | |
|---|---|---|
| 3-5 | 6-7 | |
| Skin type III: Occasionally burn, slowly tan | 20-30 min. | 15-20 min. |
| Skin type IV: Rarely burn, rapidly tan | 30-40 min. | 20-30 min. |
| Skin type V & VI: Very rarely burn, always dark | 40-60 min. | 30-40 min. |
What UV is best for tanning?
There is no safe or good UV index for tanning, since a tan indicates skin damage. If you do want to tan anyway, use sunscreen and try to go on days with the lowest possible number.
How fast can you tan in UV 6?
Example of UV Index Forecast

| 5 | Moderate | 45 minutes |
| 6 | High | 30 minutes |
| 7 | ||
| 8 | Very High | 15-25 minutes |
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.
Is the sun stronger than 30 years ago?
NASA – UV Exposure Has Increased Over the Last 30 Years, but Stabilized Since the Mid-1990s.
Why is there no ozone layer 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).
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.
What months are UV rays strongest?
Season of the year: UV rays are stronger during spring and summer months.
What state does the sun not go down?
Alaska. Alaska: The sun doesn’t set in the country of Alaska from late May to late July.
What US state gets the least sunlight?
The absolute least sunny county in the lower U.S. is Island County, Wash. On an average day, it gets only about 60 percent of the solar radiation of a typical county in Southern California. The states bordering the Great Lakes — from Minnesota to New York — are all at the bottom of the sunlight distribution.
Why is Hawaii UV index so high?
Because Hawaii is closer to the equator, it has a higher UV index than many other states. Our island community is exposed to higher-than-average levels of UV radiation that increases our risk of sunburn and skin damage. That means we need to take sun safety extra seriously.
Why is the sun so strong in Hawaii?
Due to the Hawaiian Island’s proximity to the equator, the suns rays are much stronger that what you might experience at home. (Unless of course, your home is also near the equator.)
