UV index in Tucson today

UV index in Tucson today
Before a usable live response loads, the dial above shows a labelled typical reference for Tucson (32.22°N, 110.97°W). On a typical clear day the index builds through the morning and peaks near 12:30pm at about 11 — the extreme band — before easing off toward sunset at 19:31. 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. Desert clarity and elevation make extreme UV common; the heat is obvious, but the UV dose climbs even faster.

Questions
Is it safe to tan in Tucson at midday?
Around midday Tucson 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 7:00–8:45 or 17:30–18:45, and use broad-spectrum SPF. These are estimates, not medical advice.
When is UV lowest in Tucson?
UV is lowest near sunrise (5:17) and sunset (19:31) and climbs to its peak around 12:30pm. The morning and late-afternoon tan windows — about 7:00–8:45 and 17:30–18:45 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
