For centuries, traditional Hawaiian chants have warned about an increased risk of shark bites in the fall, when the wiliwili tree blooms.

According to the state Department of Land and Natural Resources, Division of Aquatic Resources, the warning is still appropriate.

“October is the month with the greatest number of shark bites,” DAR Administrator Bruce Anderson said in a DLNR press release. “We recommend ocean users exercise a little more caution this month especially, and also through the end of the year. The chance of being bitten by a shark in Hawaiian waters is always extremely small, but does increase a bit during this time frame.”

According to DAR data, from 1980 through 2015, there were 122 unprovoked shark bites in Hawaiian waters. Twenty six of those, or 21 percent, occurred during the month of October, with well-known victims such as Michael Coots (1997) and Bethany Hamilton (2003) suffering loss of limb. So far, no October bite has been fatal.

In 2012 there were two bites in October. In October 2013 there were three, then four in October 2014, and three in October 2015.

“The three bites last October were all around O‘ahu, off different coasts of the island, and took place over a span of 20 days,” Anderson said. “Two were very serious, with victims losing part of a limb. It was an unprecedented spike, but like nearly every spike in shark incidents, the most likely explanation is just chance.”

University of Hawai‘i researchers, funded in part by DAR, have confirmed the fall spike, and offered a possible explanation, at least in part. About 25 percent of the female tiger sharks in the Northwestern Hawaiian Islands migrate to the main islands in the fall to give birth. The increased number of sharks in near shore waters, combined with their need to feed to replenish lost energy stores, may increase the likelihood of a bad encounter with a human.

“The best thing ocean users can do to minimize their risk of shark bites is to utilize beaches with lifeguards, stay near other people, and don’t go too far from shore. Also, avoid murky water and areas near stream mouths,” Anderson said.
