S.F. To Hawaii
Jay, Jack is basically right.I lived there and brought many boats to and fro, to is better, as once you catch the trades it can be a nice passage, about 2150nm form Mile rock to Diamond Head.I was in two hurricaines there, both in December, that doesn't mean they cannot arrive sooner, but most have lost their punch by the time they reach the islands.I have made that passage in nearly every month, I prefer May, but did it in January toooo, wouldn't recommend that, as we got some nasty gales on the Jan trip.The important factor for me is the Pacific High, is it in place? Are the trades doing their normal thing? Can I get a ticket on the trade train on so and so date?As soon as someone tells you "its all downhill to the islands" you'll get nailed by a gale.May, June, July are good with the high in place, and considered safe from hurricaines coming up from the south.You will get squalls, be prepared to reef, or spill wind they never last more than half and hour, usually much less, unavoidable, I've got 50kts of wind from squalls before, but there are is no wave action, but 'wind waves'.Look at the Pilot Charts for the particular month you fancy to cross, and carry an EPIRB.I'd rather do that passage than take a vessel from S.F. to Seattle...;-)
