Hi, Jan and Michel... You should be good until mid October then the
weather windows for comfortable passages become shorter and shorter. With El Niņo hitting this fall all bets are off in trying to use past weather as a predictor, however.
There are so many places to duck into on your way north or south from
San Diego, if you are prudent and err on the safe side you should be fine.
San Diego to Point C is always a cakewalk but once you turn the corner, expect taking weather and seas on the nose the whole way. Cape Mendocino is one point you want to stay well off because the confluence of
wind and sea can make it fairly dangerous. Although, I've ducked into Fort Bragg at Noyo River a couple of times going south. The coastlies there are happy to guide you in from the 1 mile buoy. I've stopped there a couple of times to wait out bad seas off the Cape. Humbolt Bay is just a little further north and if the bar is OK to cross, it is a delightful spot with a fine marina, good restaurants and friendly folks.
When and if you come north, keep a good watch as there can be a fair bit of debris from
fishing boats out for about 15 miles. Abandon Nets, lines, and stuff. Forty miles out you will be in tanker traffic coming down from
Alaska to Southern CA.
Occasionally, there is a counter
current of about 1/2
knot in a northwesterly direction from San Simeon north and out between 2 and 5 miles.
I would not advise going into the
Columbia River if it is blowing at all. Greys Harbor just north of the
Columbia River should only be attempted in daylight, with no
fog and local knowledge is strongly advised!
Give the Tatoosh Islands a wide berth as you turn into the Straits of Juan de Fuca.
Let me know if I can be of help in planning your
passage... Cheers, Phil
