High Surf Warning issued July 27 at 3:03PM HST until July 29 at 6:00PM HST by NWS Honolulu HI
Effective: Mon July 27, 2026, 3:03 PM
Expires: Tue July 28, 2026, 4:15 AM
...HIGH SURF WARNING FOR EAST FACING SHORES THROUGH WEDNESDAY AFTERNOON... .A east swell from Hurricane Fausto will continue to build tonight and peak Tuesday above High Surf Warning levels. The swell will decline on Wednesday as the system passes to the northwest. * WHAT...Surf building to 14 to 18 feet. * WHERE...East Facing shores. * WHEN...Until 6 PM HST Wednesday. * IMPACTS...Very High. Expect ocean water surging and sweeping across beaches, coastal benches, and lava flows creating the potential for impacts to coastal properties and infrastructure, including roadways. Powerful longshore and rip currents will be present at most beaches. Large breaking waves and strong currents may impact harbor entrances and channels causing challenging boat handling.
Stay away from the shoreline along the affected coasts. Be prepared for road closures. Postpone entering or leaving channels affected by the high surf until the surf subsides.
