Some friends and I went to Boca in August and stayed at a Time Share about 1/2 mile North of Deerfield Beach/Pier. While Deerfield Beach was extremely crowded, the beach in front of our condo was almost a "private" beach for us. The water was cool, but not cold, and very refreshing. It was also calm and there were gorgeous shells on the beach. About 1/2 mile north of us (maybe even less than that) we found a fabulous place to snorkle and probably could have spent our entire week right there. It was a small park. My advice to anyone looking for a great snorkling place - ask the locals !!!! Don't read brochures, etc. The people who can tell you or show you LIVE RIGHT THERE. We found this great place by talking to a lady in a jewelry store.
