The UV Index at Your Fingertips

When people talk about the weather, why don’t they ever discuss the UV index? They cover temperature, wind, and rain, but rarely a mention of the UVI. It seems like information worth keeping tabs on.

For those unfamiliar with the UV index, or ultraviolet index, it is a measure of the level of UV radiation for a given time and place. Standardized by the World Health Organization, the UV index provides a numeric value from zero to 11+. The higher the number, the higher the risk of skin and eye danger. Going out at levels of 8 or higher is not recommended without proper sun protection.

Knowing the forecasted UV index for your location can help you make sun-safe choices. You can plan your day to avoid the outdoors during periods of very high risk.

It is time that you followed the UV index like you do temperature or precipitation. With modern technology, that information can be a few simple taps away.
