I've had good days with strong NE winds and I'm no pro. Charter captains aren't going to cancel a day unless its blowing over 15.
You've got to find the fish that want to eat. That simple.

the one consistent thing I find, remembering back among the successful NE wind days, I have found success tucking on the lee side of an island, just off the seam from the wind. Sometimes go shallower than you think along this line.
