The Denver, Colorado UV index is forecasted to reach 8 on Thursday April 26th 2011. Got Film?

The UV Index is a forecast of the amount of skin damaging UV radiation expected to reach the earth's surface at the time when the sun is highest in the sky (around midday). The amount of UV radiation reaching the surface is primarily related to the elevation of the sun in the sky, the amount of ozone in the stratosphere, and the amounts of cloud cover. However, heavy cloud cover can greatly reduce ultraviolet radiation levels and surprisingly, certain types of thin cloud coverage can magnify the ultraviolet radiation.

The peak daily ultraviolet radiation level changes over the year. The strongest being at the Summer solstice (June, 21st) and the weakest at the Winter solstice (December 21st).
The UV Index can range from 0 (at night) to 11 or 12. It might even be higher in the tropics and/or at high elevations under clear skies. The UV Index does not exceed 8 in the US (8 is rare; 7 may occur on exceptional days, mostly in the two weeks around the summer solstice). However, indices of 9 and 10 are common in the Mediterranean area.
The higher the UV Index, the greater the dose rate of skin damaging (and eye damaging) UV radiation. Consequently, the higher the UV Index, the smaller the time it takes before skin or eye damage occurs. Find out about your risk and burning time with our risk indicator.
Low risk means that there is nothing to worry about - the sun will not harm you. Redness (erythema) will appear in 2 hours or more (11:00-15:00 GMT) in a UK summer
Medium risk means that the sun is not dangerous, but you should avoid being in direct sunlight for more than 1 to 2 hours. Redness (erythema) will apear after longer exposures. Burners should apply skin protection factor (SPF) 15 sun screen. All people should wear UV-A+B sun glasses
High risk means you could burn in 30 to 60 minutes. Try to keep out of direct sunlight, cover up or wear a sunscreen lotion SPF 15+. Use protective clothing.
Very high risk means that you could burn severely in 20 to 30 minutes. Stay out of direct sunlight, cover up and use a sunscreen lotion SPF 50+.
