We have been to South Beach numerous times over the years. We keep going back so we must really like it. The water is warm compared to what you would find further north at Hampton NH or York Beach ME. There isn't anything but the beach at South Beach, so if you are a beach person, for that in itself you will enjoy stretching out a chair, opening a good book and getting lost in the breeze and the sounds of the large rolling waves. The only reason I did not give it an excellent is because the one downside in the dead of summer is everyone else wants to enjoy the beach too. Parking can be a little difficult and the beach can be a little crowded. However if you go in late June or early September it is wonderful.
