The ultraviolent index is a measurement of the radiation that is capable of producing a sunburn. The intensity of the UV radiation can change depending on several factors including the season, time of day, cloud cover, altitude and the distance from the equator.
The UV index ranges from 0 to more than 11.
It is common to see values greater than 8 on the scale, during the spring and summer.
A value low on the scale means it takes a longer time to develop burns on the
skin when exposed to direct sunlight. The time can drop to less than 10 minutes
on days that see extreme levels on the UV index.
It is recommend on days that are high on the index that you apply sunscreen several times a day, wear protective clothing and limit your time in the sunlight.
