What is the UV index and why should you care?

The UV index predicts the ultraviolet radiation levels reaching the earth’s surface on a scale of 1 to 11 plus. According to the Environmental Protection Agency (EPA), a UV level of 1 or 2 is considered low risk. On the other hand, a UV level of 8 to 10 is considered very high. Anything greater than 10 is considered extreme. This scale helps people determine how to prepare for outdoor activity in terms of sun protection.

While the best practice is to always wear sun protection, keeping an eye on the UV index can help you determine when outdoor activities may be especially harmful. If the UV index is at a 3 or higher, precautions like sunscreen or a hat are especially important. Avoiding the hours when the sun is at its peak is also a responsible choice.

High levels of ultraviolet radiation can damage your skin and eyes as well as cause cancer.

To change the units from Farenheit to Celcius or vice-versa, open the Weather app and scroll down to the Settings gear icon. Tap the icon, then tap your preferred unit of measurement.
