Wind also causes the plants to lose more water through evaporation from their leaves.
Like B3 said I just use the info on labels eg south facing simply as a guide that the plant is a sun lover. All gardens vary not only which way they do face but whether the sun is blocked or filtered by neighbouring buildings, trees etc. It's all trial and error and I have a,ways found that you need to get to know your garden before you can really get a feel for the sunniest/shadier spots.
If you are on a windy corner, you could use wind tolearnt plants to create more shelter for those which are more tender. The other option would be to use trellis or something like your willow screen to filter the wind. Try and avoid anything solid as this just pushes the wind up and over the barrier making it even more turbulent and harder for the plants to cope.
