To be honest, around here during windy season (spring) and sometimes in the summer you really should just size up the rod you're using. I know that in windy situations I'm using a 6wt most of the time. That extra backbone helps punch through the wind and takes less of a toll on your arm.
But, if you don't have that luxury, try keeping your backcast high going with the wind and your forward cast low going against the wind (or vice versa depending on the direction of your cast and the wind direction).
