Most people end up getting bad sun burns instead of tans and this prevails much longer than the fun part of the picnic.
One should always take certain precautions when invading the waters in order to come back with the same face that they had gone with.
Couple of important protective measures depending on the norms and customs of your place of residence is to cover as much skin as possible as your attire while swimming in the open sea should be slightly different from that of the pool.
The part of skin that is devoid of cloth should be covered by a good quality tested skin protection lotion that works for your skin type. Take your time as well as the advice of a specialist if necessary when shopping for the sun block as perhaps after the swim suit this remains the single most important purchase before going near the water. Always carry a pair of extra clothes and a hat with you to give extra protection to your face which is the most obviously damaged part of the body because of the heat.
