WATERS FROM PT ST GEORGE TO PT ARENA AND OUT 60 NM

PZZ400-162315
325 AM PDT Fri Oct 16 2026

SYNOPSIS
North winds will be light to gentle in all waters through Friday morning. Low short period seas will allow for the sea state to be mostly controlled by a mid period northwest swell around 5 feet and another mid period southwest swell around 3 feet. Though not too steep, these opposing swells will still make for a chaotic sea state. Moderate to strong north winds will gradually rebuild first in the southern outer waters Friday night before moving northward over the weekend. Short period seas will rise in response.
