UV index in Los Angeles today

Before a usable live response loads, the dial above shows a labelled typical reference for Los Angeles (34.05°N, 118.24°W). On a typical clear day the index builds through the morning and peaks near 1pm at about 10 — the very high band — before easing off toward sunset at 20:08. 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. Coastal haze can mask high UV — the index still climbs to very high around solar noon in summer.

Questions

Is it safe to tan in Los Angeles at midday?

Around midday Los Angeles typically reaches UV 10 (very high), 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 8:00–10:00 or 16:30–18:30, and use broad-spectrum SPF. These are estimates, not medical advice.

When is UV lowest in Los Angeles?

UV is lowest near sunrise (5:42) and sunset (20:08) and climbs to its peak around 1pm. The morning and late-afternoon tan windows — about 8:00–10:00 and 16:30–18:30 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
