A high surf advisory is in effect for north- and west-facing shores of Kauaʻi and Niʻihau, and officials say large breaking waves and strong currents will make swimming hazardous through Monday morning. Lifeguards and ocean-safety crews have posted warnings at many beaches and are monitoring conditions as swells push up the coast. Residents and visitors are being urged to keep back from the water and avoid low-lying shorelines, according to Kauai Now.
What the advisory says
The National Weather Service has placed exposed north- and west-facing shores of the western island chain under the advisory, forecasting large breaking waves of 10 to 15 feet on north-facing coasts and 8 to 12 feet along west-facing shores through 6 a.m. Monday. Forecasters say the elevated surf is coming from a mix of a medium-period north-northwest swell and a shorter-period north-northeast pulse that will keep waves churning at exposed beaches. As reported by Kauai Now, the National Weather Service map shows which shorelines are most exposed.
County: stay back from the water
The County of Kaua‘i’s Ocean Safety Bureau has advised no swimming at many north-facing beaches and says warning signs are posted while lifeguards monitor the shoreline. Officials repeated the short, familiar guidance: “When in doubt, don’t go out,” and asked people to speak with lifeguards or call the Ocean Safety Bureau at 808-241-4984 for beach-specific conditions. The County of Kaua‘i issued the advisory and contact information for those seeking immediate local guidance, as stated by Kauai Now.
How the coast may be affected
High surf of this size can send water surging across normally dry beaches and rock benches, potentially causing temporary road closures and hazardous conditions for boaters near harbor entrances. Forecast models show a frontal boundary and upper-level disturbance that could change rainfall and swell patterns over the next day, so the advisory might be extended if swells hold or increase. Hawaii News Now notes the front's potential to boost surf and rain over Kaua‘i and Niʻihau.
Safety tips for beachgoers
Stay well back from the water’s edge and don’t stand on wet rocks, seawalls or benches where waves can knock people off balance; sneaker waves and strong backwash are common during these events. If someone is swept from shore, call 911 instead of attempting an in-water rescue — lifeguards have the training and equipment to respond safely. For lifeguard postings and beach-by-beach updates, county officials point to the Ocean Safety Bureau resources and safebeachday.com.
Where to get updates
Keep an eye on National Weather Service products and local outlets for changes to the advisory as the swell evolves. For the latest local details see Kauai Now and contact the County of Kaua‘i Ocean Safety Bureau for beach-specific guidance.
