FZUS56 KEKA 170353 CWFEKA Coastal Waters Forecast for Northwest California National Weather Service Eureka CA 853 PM PDT Fri Oct 16 2026 WATERS FROM PT ST GEORGE TO PT ARENA AND OUT 60 NM PZZ400-171615- 853 PM PDT Fri Oct 16 2026 .SYNOPSIS...Northerly gentle to moderate breezes expected for the coastal waters before northwesterlies increase overnight, increasing short period seas. These short period seas will mix with a mid period northwest swell and another mid period southwest swell. Though not too steep, these opposing, perpendicular swells still make for a chaotic sea state. Expect winds to first build in the southern waters with near gale force gusts south of Cape Mendocino by mid morning before spreading north to areas downwind of Cape Blanco through midday. Winds remain elevated through the weekend with continued moderate to fresh breezes. $$ PZZ450-171615- Coastal waters from Pt.
