The UV index forecasts the intensity of ultraviolet (UV) light for
any given day. The index helps people know what precautions to take to avoid
sunburn or other skin damage from being in the sun too long.
The UV index is listed on the weather page of many daily
newspapers. Sun protection measures, such as wearing sunscreen, should always
be taken when the UV index is 5 or above. The UV index is measured on a scale
of 0 to 11+.
