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.
