Yes, the waters surrounding Alcatraz in San Francisco Bay do have Great White Sharks. Ever been kitesurfing, windsurfing, swimming, or kayaking in the bay? You may have been very close to one of these big guys. This video was recording 2 days ago on October 10th, 2015.
Kinda cool… Kinda scary…
The San Francisco Chronicle is saying this was the first Great White Shark attack in modern history.
“Savage nature was on display when a great white shark devoured a seal just a few feet off Alcatraz Island in full view of gawking tourists, the first attack by the ferocious finned predator in the modern history of San Francisco Bay.” – San Francisco Chronicle
Some people are blaming the current warm waters of El Nino on the rise in shark attacks this year. The water at Ocean Beach, San Francisco is currently 64ºF, which is crazy hot. It’s usually about 55ºF this time of year…
San Francisco is within the “Red Triangle” where more Great White Shark attacks on humans have occurred than anywhere else on Earth.
“The Red Triangle is the colloquial name of a roughly triangle-shaped region off the coast of northern California, extending from Bodega Bay, north of San Francisco, out slightly beyond the Farallon Islands, and down to the Big Sur region, south of Monterey. The area has a very large population of marine mammals, such as elephant seals, harbor seals, sea otters, and sea lions, which are favored meals of great white sharks. Around thirty-eight percent of recorded great white shark attacks on humans in the United States have occurred within the Red Triangle — eleven percent of the worldwide total. The area encompasses the beaches of the heavily populated San Francisco Bay Area, and many people enjoy surfing, windsurfing, swimming and diving in these waters. Even with the ever increasing numbers of people entering the water, sightings and encounters with the elusive sharks are still extremely rare.” – wikipedia
