Well it's not the best weather window for those who plan to leave down the coast now.    That is unless you like beating in southerly winds sometime blowing in excess of 20 knots with lots of rain off and on.   The pattern looks to be surprisingly stable, with a trough and upper level low perched right off the Washington/Oregon Coast and high pressure in our nation's interior solidly entrenched blocking the low from moving inland, thus not allowing the pattern to change a whole heck of a lot at least for the next 5 days and probably beyond.   The forecast discussion from the National Weather Service says the various weather models are all in agreement on this pattern continuing, which usually means, that well, the pattern will continue.    It's hard to nail down specific times for when the short wave systems will pulse into our coastal waters, save what looks to be a fairly organized cold front that is on tap for Monday, most likely in the afternoon.   In the short term things look light and out of the North pretty much for the entire coast from Flattery to SF.   From approx. Cape Mendocino North, the gradients will turn more southerly sometime later today and it looks as though they will stay that way through my forecast period.    For the California waters South of Cape Mendocino gradients will be relatively light bringing light to moderate breeze mostly out of the N.

Cape Flattery to Cape Mendocino
Today – Light winds starting out of the N. 0 – 10 knots changing over to Southerly in the afternoon or evening to 15 knots.

Monday – A cold front is scheduled for your sailing pleasure with S winds changing to SW with frontal passage in the afternoon.  Wind speeds 10-25 knots with definitely the possibility of higher gusts.  And oh yes there will be rain.

Tues through Thurs - South winds ranging from 5 – 25, rain at times

Seas - Swell 3-5' wind waves 1-6' (depending on how much wind)

Cape Mendocino to San Francisco
Today through Thursday  - Light to moderate winds ranging from 0-20 knots.  The most wind will be as you get closer to SF and with the diurnal cycle it is possible there will be a few hours here and there in excess of that 20 knots.   So be prepared, but I think winds will be more on the light side.     It is possible the Southerlies will reach below Cape Mendocino at times (especially Monday).    You may find yourself beating in light to moderate southerlies if you are in the Northern portion of this forecast area.

Seas should be manageable with a swell 6' and under and wind waves to 1-4 feet.
