How to enjoy the Sun safely? The UV (Ultraviolet Radiation) index is an international standard measurement of how strong the ultraviolet (UV) radiation from the sun. Knowing how to limit exposure to UV radiation is the key to a healthy and fun sun experience
The ozone layer guards the Earth from harmful UV radiation. Ozone depletion, seasonal and weather variations cause different amounts of UV radiation to reach the Earth at any given time. Developed by the National Weather Service (NWS) and EPA, the UV Index predicts the next day's ultraviolet radiation levels on a 1-11+ scale helping you to determine the appropriate sun-protective behaviors.
