Marine Zone Forecast


Synopsis: Broad high pressure will allow for generally benign boating conditions through the middle of the week. Modest SE/SSE flow should persist through mid week. An approaching front later in the week may result in deteriorating marine conditions, as a fetch of NW winds acts to increase surf heights. Swell activity may develop downstream of the front as well, which could persist into the weekend.
