ʻAlenuihāhā Channel

Effective April 1, 2025 HCSA's official position statement regarding the ʻAlenuihāhā, Kaulakahi, Kaʻieʻiewaho  and Molokaʻi (Kaiwi) Channels:

In addition to considering sea and weather conditions and sun exposure duration, a strong recommendation supporting human safety can be made to structure channel swimming so that a swimmer transits through the zoogeographical habitat (the deepest portions of the channel) of Isistius spp. (cookiecutter sharks) during moonlit nights or daytime.
