Always be cautious. Skin and eyes can be affected swiftly without protection. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days. Staying too long under direct sunlight isn't advisable, particularly for those who burn quickly. Use at least a 30 SPF sunscreen for protection. Beware! The strength of the UV rays is significantly increased by the reflection of the water and sand.
