UV Index in El Paso, Texas Today

What the UV index means in El Paso

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 El Paso, 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.

UV in El Paso: geography and seasons

At 31.8° N, El Paso sits in the subtropics. UV is strong for much of the year and peaks around June and July, when the sun climbs almost directly overhead at midday. The city sits about 1,133 m (3,717 ft) above sea level. Because UV rises roughly 10% for every 1,000 m of altitude, that elevation lifts El Paso's UV noticeably above sea-level cities at the same latitude.
