How to Prevent Sun Damage

The forecast UV index provides a UV forecast for the next ten days corresponding the daily maximum UV index that is expected to occur at a given location. Six risk level categories (0-2 Minimal, 3-4 Low, 5-6 Moderate, 7-9 High, 10 Very High, 10+ Extreme) are used to categorize the calculated skin-damaging UV radiation in agreement with recommendations proposed by dermatologists.
Meteorologists consider cloud cover, visibility, atmospheric ozone concentration, solar elevation and altitude above sea level when developing the forecast UV index.
