What the UV index means in Austin

The UV index is a simple 0 to 11+ scale for the strength of the sun's ultraviolet radiation. The higher the number, the faster unprotected skin can burn. In Austin, like everywhere, the reading rises and falls through the day and shifts with the seasons, cloud cover, and how high the sun sits in the sky.

Use the live reading at the top of this page to decide what you need right now. As a rule of thumb: at UV 3 or above, wear sunscreen and a hat; at UV 6 and above, add shade during the middle of the day; at UV 8 and above, treat midday sun with real caution.
