UV index in Las Vegas today
Before a usable live response loads, the dial above shows a labelled typical reference for Las Vegas (36.17°N, 115.14°W). On a typical clear day the index builds through the morning and peaks near 1pm at about 11 — the extreme band — before easing off toward sunset at 20:00. When live hydration succeeds, the card replaces the reference with a current observation and forecast. Use the verified current value, not the temperature, to decide whether it is a tan window or a cover-up hour. High desert sun and thin cloud cover make extreme summer readings the norm rather than the exception.

Questions
Is it safe to tan in Las Vegas at midday?
Around midday Las Vegas typically reaches UV 11 (extreme), strong enough to burn unprotected skin quickly. It is better used as shade-first time. For a gentler session, aim for the lower-UV windows around 7:30–9:30 or 17:30–19:00, and use broad-spectrum SPF. These are estimates, not medical advice.
When is UV lowest in Las Vegas?
UV is lowest near sunrise (5:24) and sunset (20:00) and climbs to its peak around 1pm. The morning and late-afternoon tan windows — about 7:30–9:30 and 17:30–19:00 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
