I know that one of the high priorities on many peoples minds is to get in the Sun as fast as they can and for as long as they can to get a tan to be proud of when they return home. But.........
BEWARE OF THE SUN !
If you are fair skinned or even if not, USE Sun protection cream or lotion BEFORE hitting the beach. Even if just walking around town you can suffer from the Suns effects.
Buy and wear a Hat or Cap to protect the top of your head.
DO NOT sunbathe on the first day for more than TEN MINUTES ! I know that does not seem a lot of time but to avoid looking like a lobster and feeling itchy and uncomfortable, ten minutes only is recommended. Then gradually lengthen the time each day.
Remember that when in the Sea or Pool, the water acts like a mirror and reflects extra Ultraviolet back at you.
Seawater having a high salt concentration, has the same effect as putting salt on Pork Crackling ! So shower off as soon as you come out of the sea or saltwater swimming pool. By the way, beware of the little showers on the beach. They are intended for removing sand and are SALT water; so a shower in your apartment / hotel is better unless you are CERTAIN that the water is not salty!
The nearest weekend to the 24th of June celebrates San Juan, local children are able to purchase fireworks and then they set them off where ever they fancy. A few of them were actually throwing the fireworks which was a bit frightening as we had young children in buggies.
