The last months on the year require more atention of the beachgoers. It is on the high tide period that the firstaiders register higher numbers of rescue from the sea. A important issue to care is a consumtion of alcohol. Most cases, the victims had drunk alcohol and enterd the sea. It is a hug risk, even worse if you don't know the place and ignore the guidlines of the lifeguards, who many times become "invisible" from the eyes of the beachgoers, as they belieave to be out of danger.
