Questions
Is it safe to tan in Portland at midday?
Around midday Portland typically reaches UV 7 (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 8:30–10:30 or 18:00–20:00, and use broad-spectrum SPF. These are estimates, not medical advice.
When is UV lowest in Portland?
UV is lowest near sunrise (5:22) and sunset (21:00) and climbs to its peak around 1:15pm. The morning and late-afternoon tan windows — about 8:30–10:30 and 18:00–20:00 — are the lower-UV parts of daylight that are still warm enough to be useful for a careful tan.
