Seas will build around middle of the week due to a combination of short period wind waves and long period west swell. North winds will increase for the latter part of the work week.

Synopsis Dry weather accompanied by mild afternoons and cool
nights is forecast to give way to cloudier conditions and possible
rain next weekend.

Discussion An upper ridge remains centered over the west coast,
and will support a continuation of mild afternoons and cool
nights through early to mid week. Thereafter, model guidance shows
the upper ridge breaking down Thursday into Friday as a northern
stream trough moves across the pacific northwest. This will drive
a weak front southward across nwrn ca Thursday night, resulting in
an increase in clouds, and a very modest increase in
precipitation potential over mainly del norte county. Strong
westerly moisture flux is then forecast to spread across coastal
or and wa during the weekend. The far southern periphery of this
moistures will potentially impact northern humboldt county,
northern trinty county, and much of del norte county. Thus,
inherited pop values have been raised accordingly.

Aviation Vfr conditions through today. The closest piece of
clouds are at least 200 miles west of the redwood coast. Do
expectVFR conditions to prevail for the next 24 hours. Don't
expect low clouds and fog to form in all terminals as we are still
under the influence of this anomalously dry airmass. Rcl

Marine Fairly tranquil marine weather pattern will continue
through the next few days. A strong high pressure remains over
western north america, while the main storm track remains well
west of the west coast. By middle of the week, a thermal trough is
forecasted to develop along the ca coast, and this will enhance
the northerly pressure gradient over NW ca waters at that time.

Light and variable winds in NW ca coastal waters through first
part of Sunday. Winds will then turn back to the south late this
afternoon. South winds will continue through Monday evening,
before flipping back to the north Monday night. Looks like there
will be a period of stronger north wind starting on Wednesday,
courtesy of the stronger northerly pressure gradient over NW ca
waters. North winds will increase further at the end of the work
week.

With the light winds, there is not much wind waves that we are
dealing with. Combined seas is around 5 to 7 feet through Monday
night. There is a weak long period south swell, with a mid period
decaying southwest swell. There will be a fresh west swell moving
into the waters tonight and continue into Tuesday night. Looks
like more significant wind waves will start to develop on
Wednesday, besides another fresh northwest swell. Looks like seas
will turn hazardous starting middle of the week.

There are no marine hazards in effect at this time. Rcl

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
