Texas UV Index by City
Texas is wide enough that UV shifts noticeably from the Gulf Coast to the high desert of El Paso. Pick your city below for a labelled typical hourly reference and a location-aware current-UV check.
UV across Texas rises as you move south and west, with lower-latitude San Antonio and high-altitude, dry El Paso often peaking above Dallas and Fort Worth in the north. The index is strongest at midday and from late spring through early fall, regularly reaching the EPA high (6-7) and very high (8+) bands, and the WHO advises protecting from UV 3 and up. Each linked city page starts with a labelled typical reference and shows current and forecast UV only after a usable response; these are estimates to manage burn risk, not a promise of a safe tan or medical advice, and altitude in El Paso plus Gulf humidity and sweat can change real exposure.

Each city page starts with a labelled typical clear-sky reference for Texas and replaces it only after a usable current UV response. Failed requests remain visibly labelled as reference data. Estimates only — not medical advice.
Questions
Which Texas city has the highest UV?
El Paso and San Antonio tend to see the highest typical peak UV: El Paso because of its higher elevation and dry, clear desert air, and San Antonio because of its lower latitude, both often reaching the EPA very high (8+) band on clear summer middays. Northern Dallas and Fort Worth run high but usually a step below. Higher elevation can strengthen UV, so use each city page's current-UV check before acting. These are estimates, not medical advice.
When is UV lowest in Texas?
UV is typically lowest in the early morning and late afternoon, and seasonally during the winter months when the sun is lower in the sky. Even so, the EPA notes UV 3+ can occur on bright winter days, especially in southern and high-elevation Texas, and clouds, altitude and sweat can change real exposure. Use each city page's labelled reference for orientation and its current forecast after a usable update.
Is it safe to tan in Texas at midday?
Texas middays (roughly 10am-4pm) commonly sit in the EPA high (6-7) or very high (8+) bands, so the WHO advice to protect from UV 3+ applies and burn risk is greatest then. No tan is truly safe because any tanning is UV damage; if you're outdoors, the FDA recommends broad-spectrum SPF 30+ reapplied every 2 hours and after swimming or sweating, plus shade and clothing. Our tanning-time figures are risk-managed estimates, not medical advice, and your Fitzpatrick skin type, medications, altitude and reflective surfaces all change real risk.
