People planning to swim or snorkel on Kauaʻi’s north- and west-facing shores should follow the county’s November 11 high-surf advice to stay out of the water through Thursday, November 12, Hawaiʻi Standard Time. The notice applies to those shore exposures and includes other recreational ocean activities. Check for a new notice before setting out on a later day.
Read the county notice for the affected shoreline
The Kauaʻi Ocean Safety Bureau bulletin was sent at 10:11 a.m. local time on November 11. It describes a north-northwest swell and says the National Weather Service high-surf advisory for north- and west-facing shores of Kauaʻi and Niʻihau was then scheduled to run until 6 p.m. Thursday local time. Those details are tied to the issue time. A forecast end time may be updated, and the county’s advice concerns what to do at the shore.
The county bulletin describes forecast peaks of 18 to 24 feet for exposed north-facing shores and 14 to 18 feet for exposed west-facing shores. These are reported forecast ranges, not measurements at individual swimming sites. The county says large breaking waves can also put people along the shoreline at risk and asks visitors to heed warning signs.
Check the specific beach and your intended activity
Begin with the current National Weather Service Honolulu advisories for the island and shoreline. Then open the individual beach on the Kauaʻi beach conditions map cited by the county. Its north shore list includes Hanalei Bay, Hāʻena and Keʻe. The map says its information may lag actual conditions. Use it to identify the right location and plan whom to ask, then consult posted signs and the on-duty lifeguard before entering the water.
Changing beaches changes the question. A shoreline outside the named exposure can have separate hazards and access restrictions. Confirm that the exact location supports the planned activity and heed any local advice. If the county advises staying out of the water at your intended site, make a shore-based plan away from breaking waves or postpone the water activity.
Recheck after the published advisory time
Keep the notice date and time zone with any shared travel plan. Read current warnings and ask a lifeguard about the specific entry point on the day you return. The county alert was issued November 11, 2026, Hawaiʻi time. The bulletin and live information links were reviewed November 12, 2026, Asia/Shanghai time.
