What is the UV Index? The UV Index is a tool you can use to protect yourself from UV radiation. It tells you the times during the day that you need to be SunSmart. The UV Index divides UV radiation levels into: low (1-2) moderate (3-5) high (6-7) very high (8-10) extreme (11 and above) The UVI is an international standard index that describes the level of solar UV radiation on the earth's surface. The index ranges from 0 to 11+ and the values are grouped into various exposure categories. A higher index value indicates a greater potential for harmful effects to the skin and eyes Hourly UV index forecast for today and tomorrow. Skin protection. Sunscreen The UV Index was developed to help Canadians protect themselves from the sun's damaging UV (ultraviolet) rays.

The UV index (UVI) is a standard measurement of erythemal (sun-burn causing) UV intensity that gives a more objective measure than the old time to burn (which cannot account for skin tone). The scale is open-ended, but a UVI of greater than 10 is extreme and a UVI of less than 3 is low The UV index is a measure of the potential harm of UV radiation on human skin. The higher the UV index, the greater the potential for damage to the skin and eye, and the less time it takes for harm to occur. For Hong Kong, UV index can often exceed 10 on a sunny day in the summer This means that the UV index could be higher than currently indicated in our forecasts particularly if forecast cloud amounts are low.
