They lose a lot of them. In summer, the water is as warm as a bathtub, the air is hot but there is always a stiff breeze on the beach. Even in summer, I usually close the windows late at night because it gets too damp and chilly in the early morning hours. There are ceiling fans in all the bedrooms. In the winter unless there is a big storm from the north the water is still quite warm enough for swimming.
Some travel books write that there is always wind and waves on the beach.
Nothing could be further from the truth. Most days onshore breeze blow moderately and the sea is placid and totally devoid of waves all morning. In the afternoon, usual around 1 or 2 the wind begins to shift and blows in strongly. Still, it is not a heavy surf, just smaller whitecaps but still fine for swimming. At sunset the breeze usually slows to a breeze again.
