Mr Fairchild told 9News seeing leopard sharks this far into November “is unusual”.
“They usually show up in the summer, July to October, but for some reason they are still here in high numbers,” he said.
Every year, thousands of leopard sharks make their way to the warm waters to breed and hatch their young.
Despite growing to an average length of 2.4 metres, Mr Fairchild said the animals are very gentle.
“I see them and swim with them daily,” he said.
Mr Fairchild is no stranger to large sharks.
He routinely photographs great whites off the San Diego coastline.
Just last month he captured an incredible encounter between a large great white who circled a young child on his board.
The pair regarded each other with curiosity before the shark swam away.
Experts say great white shark populations are thriving in California and along parts of the east coast of America.
