Maui County officials closed about two miles of shoreline, which includes the Kamaole Beach Parks.
Authorities posted signs directing people to stay out of the water because of the sightings, the county said, and the Maui Fire Department was assessing the safety of the waters throughout the day Tuesday.
The beaches were closed Monday after three to five tiger sharks were spotted. A helicopter crew communicated with people still in the water to tell them to return to shore.
There are no reports of shark-related injuries on this stretch of coastline from the past two days, Maui County said.
Other shark attacks this year in Hawaii
A month later, a 65-year-old man, optometrist Dr. Thomas Smiley, was killed while swimming off Maui’s Kaanapali Beach, about 30 miles up the coast from Kamaole, where this week’s sharks were seen.
At the time, Keliikipi told CNN he didn’t have any plans to quit venturing into the waves, and he said knowing surfers who’ve been attacked by sharks was “not common, but it’s not uncommon, either.”
