Kauai County Ocean Safety officials Monday closed Hanalei Bay to swimming until further notice due to shark sightings.

Lifeguards reported that two large sharks were seen about a hundred feet from shore fronting a surf spot known as “Pine Trees,” the county said.

No-swimming signs have been posted along the beach and the public is advised to stay out of the water until further notice. The beach will remain closed until at least Tuesday morning.

There have been eight reported shark attacks in Hawaii this year, including four since Oct. 18. In the most recent incident off Kauai, an 8- to 10-foot shark bit the board of a surfer Nov. 4 near Davidson’s surf break in Kekaha. The male surfer, who was in a group of eight to 10 surfers, was not hurt.
