Well over 5,000 athletes a year successfully swim from Alcatraz to San Francisco. The key is to swim during "slack tide", when the currents are neither coming into the bay (flood tide) nor going out of the bay (ebb tide.) There are two men who have made the swim over 1,000 times apiece.
Most athletes wear wetsuits, but probably about a thousand do it without wetsuits. These athletes are acclimated by swimming in the bay almost daily. The water in the San Francisco by hovers around 50 degrees year-round... much too cold for most swimmers.
Recently, (2010) scientists who had tagged Great White Sharks at the Farallon Islands found that 7 of them entered the bay. However, there has never been a recorded shark attack in the San Francisco Bay.

No, there are just non-man eating sharks around the bay.

Well Rough sharks live in the Pacific Ocean most of the time and most of the rough sharks live around the Golden Gate Bridge where Alcatraz was (a prison on a island in the San Francisco Bay).
