Implement all key precautions. Warding off sun damage is critical.

Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. It's best to minimize time under the direct sun if you burn easily. Protect your skin with a sunscreen of at least 30 SPF. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
