UV index in Portland today
Before a usable live response loads, the dial above shows a labelled typical reference for Portland (45.52°N, 122.68°W). On a typical clear day the index builds through the morning and peaks near 1:15pm at about 7 — the high band — before easing off toward sunset at 21:00. 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. Cloud cover varies, but clear summer afternoons in the Willamette Valley reach high UV well after lunch.

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.
