The north wind on the OR coast are generally much weaker than the winds south of Fort Bragg, CA. That doesn't mean they're fun to ride against, but they aren't the kind that bring you to a standstill like you get around Point Arena. You can substitute hills for wind by riding some of the parallel roads through the coast range, like the Lost Coast in Mendocino/Humboldt and some of the similar routes through Sonoma County. There's few of these in OR as well, but many of them involve unpaved roads.

If you want to ride north, you're likely to find north winds in the summer. From the delta to just north of Redding is the one exception. After that, the only non-north winds will be driven by either a temporary weather system (If you get a tail wind, don't stop until it does even if you end up riding all night.), or some eddy effects from a local mountain. If you're an early-bird you can mitigate the wind since it usually doesn't hit its stride until after 10:00 AM and often much later.
