What is the UV Index?
The UV (ultraviolet) Index categorizes the level of UV radiation that is reaching the Earth’s surface. This is similar to a weather forecast, but instead of predicting the weather it predicts the expected risk of overexposure to UV rays. A higher UV Index means there is more UV radiation present, which ultimately means there is a higher risk of skin damage.
Between 10 am and 4 pm, the UV Index will typically peak as the highest levels of UV radiation can be measured during mid-day. UV radiation provided by the sun is emitted in three bands: UVA, UVB, and UVC. The ozone layer provides protection from UVC and most UVB, but both UVA and some UVB reach the earth’s surface and are responsible for skin damage.
Knowing the UV Index for your area is important, especially if you are planning on spending time outdoors. Below is an easy guide to reading the UV Index Scale. For more information about the UV Index click here.
