UV index in Rosetta in January

LowModerateHighVery highExtreme

Clear-sky midday UV in January peaks around 3 — enough to warrant sun protection. The full-year curve, shaded by WHO exposure level, is below.

Under clear skies, the midday UV index in Rosetta peaks around June 20 at about 10 (extreme) — sunscreen, a hat and midday shade are essential. It bottoms out near January 11 at about 3 (moderate).

The index reaches 3 or more — the level where the WHO recommends sun protection — every month of the year.
