actually, prevailing winds are prone to directional changes depending on the weather pattern moving through. a storm may come out of the west as it moves east across the country, but a high pressure system will have clockwise wind so the actual direction of the prevailing winds will change depending on if the center of the system passes to your north or south, etc. low pressure system is opposite.
here in kansas, we do get a lot of cold north winds in the winter, but the general direction of hot, drying winds in the summer is out of the south and west. you need a short hedge to provide some shade and windbreak protection from the south wind for delicate summer plants.
here is the k-state info on windbreaks.... lots of good info there, especially on snow drifting.
i would think you could still save a lot of your view and plant a windbreak if you have time to wait for it to grow. otherwise, i would consider a fence and some more fasteners for your siding and shingles!
