Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. After a swim or an outdoor workout, generously apply and regularly reapply a sunscreen with at least SPF 30, even if the day is cloudy. Caution! The mirror effect of sand and water ups the UV radiation strength.
