Coastal Waters Forecast for Northwest California
National Weather Service Eureka CA
FOR NORTHERN CALIFORNIA WATERS.A transition from active weather to heavy swell conditions is underway. In the wake of a weak cold front, winds continue to diminish with the primary hazard being a heavy, long-period westerly swell continuing into Monday, peaking late tonight.
WATERS FROM PT ST GEORGE TO PT ARENA AND OUT 60 NM Key Hazards & Marine Impacts: * Heavy Swell: Expect combined seas to build to 11–13 feet at 16 seconds by this evening. These conditions will create hazardous bar crossings and steep seas in the inner waters, persisting through Monday afternoon. * Coastal Flooding: High astronomical tides combined with residual surge will likely cause minor flooding around Humboldt Bay (including King Salmon and Arcata Bottoms) during the late morning high tide cycle today. * Sneaker Waves & Surf: Breakers up to 16 feet are expected at west and northwest facing beaches. While the swell is large, the long period (16s+) maintains a high risk for unexpected wave run-up on beaches and jetties. Looking Ahead: High pressure will build over the waters by Tuesday, leading to a period of light winds and subsiding seas through midweek. Another long-period swell is signaled for late Thursday into Friday.
