Having full respect for the unpredictability of the ocean.

Is there a typically better month for calmer sea's in the NW?
This trip is on our list and I am aware there are many factor's, thought I would check on "typical" weather and ocean conditions.
 
Being the cautious person I am, I think a trip like you are proposing would hold more grief, than adventure. :crook

my thought is... :idea

How about trailering your boat to Anacortes and go from there? :wink
 
I'm gathering similar information for a trip in the next year or two. This thread over on Trawler Forum has a lot of good info.

ASD and the Inside Passage

It follows a boat from the Columbia River up to Alaska and back. It's quite a long thread but very interesting. You'll get an idea of what the trip is like, when they went, where they stayed, etc.
 
Just off the top of my head, you should loo for data that backs up your decision, I would say late july or early fogest. i think that is when we have longer more stable weather windows. In the end it just depend on the weather that year.
 
"12 knots and 13 uncomfortable hours at the helm" and that's with good weather.

It makes me appreciate how lucky I am. My C Dory can go from Portland to Port Angeles in just over 4 hours on 12 gallons of gas in any sea conditions. I average 50 knots even with a stop at a Starbucks.

What boat do you have, Riverjohn?

Did that trip this year in my Cape Dory sailboat. Left Portland on may 31. Got to Westport on June 2, high winds on the nose. Left Westport on June 3, got to within 20 miles of LaPush and seas built to 8 feet and had to turn around and sail back to Westport. Stuck there for 5 days. Finally arrived in Victoria on June 10. Knew I left too early but wanted a whole summer in the san juans and points north so took the chance. Will probably sail back next spring around end of June, first of July. August is a good month but July has treated me better in the past.

On the hunt! Its looking like a 22 Cruiser or 23 Venture...

Yes Trailering is a thought as well, to answer another post.
 
The first question I am going to ask, is what boat do you have?

Personally, and I have done a lot of coastal and ocean cruising in sailboatsts/motorsailers, including a number of trips up and down the coast, I would trailer the boat to Anacortes, or some convent place.

You have to look at the xxx days ahead of the trip--and see what the weather is gong to be. There is never a weather guarantee. A C Dory is fairly fast, but this is a fairly long trip, with some very open stretches of water and no easy harbor.

As for best month May thru August--I think it is going to be a crap shoot. Don't forget the conditions in the straights also.
 
Historically, late July to mid August have been the best times to be out in the ocean on our coast and during that time frame one often would get 3-4 days out of 5 of fairly flat water. The past two years have been different though with more winds from the N, more often than in the previous 10. Getting from Astoria to Westport isn't that tough but one does have to time the trip to cross two bars under reasonable conditions. Westport to LaPush is a longer crossing and there's no place in between to hide. La Push to Neah Bay is a relatively quick trip and after that the rest is fairly easy - especially going eastbound.

The Strait of Juan de Fuca can get nasty but in the summer, it's usually calm winds in the early AM with rising winds mid morning through the afternoon. Often the ocean is nicer than the strait in the afternoon since the strait tends to funnel winds.

The proposed trip is very doable (safely) in a C-Dory 22 or 23. That said, there are several precautions to note. First, the ocean can be quite nasty both in the open and at the bars. The entrance to the Columbia river and Westport can be quite dangerous on strong outgoing tides and are often restricted by the coast guard. Restricted means it's illegal to cross unless your boat meets the specifications of the restrictions. Restrictions can range from no boats under 16 to no boats of any kind may cross. The entrance to the Strait of Juan de Fuca can also be rough on strong outgoing tides but it's a pussy cat relative to the Columbia River bar.

Second, this is not a trip to be done be someone with little or no time in boat or little or no time in the ocean. When I say it's easily doable, I say that with the experience of a few 100 days in the ocean in a C-Dory 22, a C-Dory Tomcat and a few other boats. I've also crossed the Columbia River and Westport bars dozens of times. I now know what the ocean will look like with given forecasted sea states and I know what the bars are likely to look like under various combinations of sea state and tide exchanges. That experience allows me to make better go/no-go decisions and allows me to better handle the boat in various sea states. There's no replacement for experience but there are ways to learn more quickly - going out with others who are more experienced, taking various courses etc. But until you've seen and experienced various ocean conditions in person, it's hard to look at a current or forecasted sea state and know if that will be comfortable, uncomfortable or downright dangerous. For example, 8-10' swells. That sounds dangerous to many. BUT if they are 8-10' long period (20s) swells with little to no wind on top, they are very gentle and easy to manage. 8-10' swells at 8s with 15kts of wind are dangerous to boats our size. Even 3-4' waves can be very difficult to manage if they are short period and mixed with wind. Once you seen and experienced a variety of sea states, you can produce a fairly accurate mental picture of what it's like to be in a given measured or forecasted state.

Third, you need to understand the forecasts and gain some experience with them to understand how reliable/unreliable they can be. If there's a forecasted multi-day window of low winds and calm seas, the middle days of that forecast have a much higher probability of being correct than the beginning or end days of the forecast. Forecasts often shift a day or two and they can be wrong. Forecasts of ocean conditions are fairly reliable 3-4 days out but no so reliable beyond 4 days. For a multi-day trip, you need to leave plenty of flexibility in the schedule (e.g. almost no schedule) to allow for the possibility of sitting in port for several days until the weather is better. Having a backup bailout plan in which someone can drive the trailer to your location is not a bad idea either. The worst decisions often get made when someone "Has to be" at place x by time y and the ocean isn't in a good state.

Fourth, you need to properly equip yourself and the boat for the trip. Good life jackets, good radios (with a backup), good navigation equipment (with a backup), twin engines or a single and a good kicker and radar are all recommended. I have a life raft on my boat but I wouldn't make that an absolute requirement if you are otherwise well equipped and a safe operator. You will be nearshore for all of trip. The waters off our coast are often foggy so I think radar is essential. It's not enough to just own the equipment, you also need to be able to use it well. That's not difficult but again experience is valuable.

While it is faster and cheaper to trailer the boat to the San Juans, the scenery off our coast is also spectacular in it's own way and is very worth seeing. The rocky coastline between La Push and Neah Bay is particularly spectacular (but you might not see it due to fog in a single trip). You're also more likely to see massive numbers of humpback whales in the ocean than near the San Juans (but you can see them there also). It's only about 65-70 miles from Astoria to Westport or a 3-5 hour trip depending on conditions. Westport to LaPush is about 80 miles and La Push to Neah Bay is about 50 miles. After that, you have the Strait of Juan de Fuca. There are many ports along the way there and while it can be nasty, I see it as far less dangerous than the ocean segments. Once you're into the Puget sound/San Juans, the water can occasionally be rough in certain places but rarely is it dangerous (unless you run into one of the many well charted rocks). All the longer segments can be done in one day without pushing it. Most days in late July or August are fairly calm - especially in the early AM. May and June are, in general, much rougher than July and August. So to sum up, such a trip is very doable and can be quite enjoyable with the right preparation and experience. It's not a trip for the novice though.
 
Rogerbum's treatise is spot on. Living in Astoria, we have enormous respect for the stretch of ocean from here to Neah Bay, and Roger has it nailed.

this is the best advice you have gotten so far. You have to look at the whole forecast not just the wind speed or just the swell. This is even more important when crossing the bars. You have to know what the tide direction and flow is at the bar when you want to cross and how the wind/swell height and direction will effect it. Some times just waiting on the ocean for the right conditions at the bar can make all the difference in the world.
 
What a great reply by rogerbum. This entire thread reminds me of the best advice I've ever received about boating, "The most dangerous thing to have on the water is a strict schedule."

I was checking out some bar conditions and now everytime I go to YouTube stuff like these are my recommended videos.

That's a good video!

I have been over the Columbia bar more than once in pretty snotty conditions, not something I will shoot for. Then I have experience in Westport Washington even worse.

The sea is not at all a forgiving place to be.
 
A book on the Pacific Northwest Weather, I have enjoyed is here.

Excellent post by Roger! I'll have to admit that I stayed off shore far enough that I could not really enjoy the rocky coast up close and personal--but I have seen a lot of those... I always want a bit of sea room between me and the shore, just in case something does go wrong.

I was leaving Coos Bay, on my first trip up North. Asked the Coast Guard about the state of the bar, and they said "OK"--As we went out about a 10 foot breaker came across our deck over the pilot house. CG immediately closed the bar--and a motor boat which had been traveling about the same time frame behind us and a faster speed was refused entry. He had to slow way down to have enough fuel to make the next harbor. So I have always thought one needs to plan for contingencies. Also to look at weather in the port you are going too as important as the weather in the port you are departing from.
