Questions
Is it safe to tan in Honolulu at midday?
Around midday Honolulu 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 7:30–9:00 or 16:30–18:00, and use broad-spectrum SPF. These are estimates, not medical advice.
When is UV lowest in Honolulu?
UV is lowest near sunrise (5:52) and sunset (19:10) and climbs to its peak around 12:30pm. The morning and late-afternoon tan windows — about 7:30–9:00 and 16:30–18:00 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
