UV index in Key West today

UV index in Key West today
Before a usable live response loads, the dial above shows a labelled typical reference for Key West (24.56°N, 81.78°W). On a typical clear day the index builds through the morning and peaks near 1:15pm at about 12 — the extreme band — before easing off toward sunset at 20:15. 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. As the southernmost US city near 24.5 degrees north, the sun climbs nearly overhead in summer and ocean reflection compounds it, so UV regularly hits the EPA 'extreme' ceiling; this is an estimate, not medical advice.

Questions
Is it safe to tan in Key West at midday?
Around midday Key West typically reaches UV 12 (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 7:45-9:00 or 18:00-19:30, and use broad-spectrum SPF. These are estimates, not medical advice.
When is UV lowest in Key West?
UV is lowest near sunrise (6:35) and sunset (20:15) and climbs to its peak around 1:15pm. The morning and late-afternoon tan windows — about 7:45-9:00 and 18:00-19:30 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
