Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Tightly woven clothing, when worn loosely, shields effectively against the Sun. Despite the clouds, sunscreen with an SPF of at least 30 should be used liberally and reapplied frequently, especially after a swim or outdoor workout. Warning! Sand and water reflections boost the intensity of UV exposure.
