I don't think there is a place on the west coast where it is guaranteed that you will have wind everyday... in 3-4 weeks.
You will have to wait for the forecast
There was no wind in Gero last year between Christmas and new year, but it was blowing down south. It was the opposite 2 years ago.
So yeah, this is why I never plan what I will do over the Christmas break. It gives me more flexibility to travel wherever I want, where there is wind of course
