Well the wind would becoming predominately from the north west. I am worried about swirling winds.
Waiting for a SSW wind to hunt it is one option. That creek bottom should have some up-draft behaviors with a SSW wind.
With a N or W wind, there will most likely be some bit of swirling, but the amount of swirl will vary as wind speed changes. Even swirling winds are usually part of a pattern. Not an easy to predict pattern, but none the less, the patterns are still there. Swirling is a pattern in of itself. It's an eddy. But every eddy, whether its a water eddy in a stream or a wind eddy in the woods, has an edge. There are seams where an eddy begins and where it ends. You may have to move out a little from the spot that you would
like to hunt in order to find the areas where wind is a little more stable.
Swirling winds may be an eddy, but eventually that wind has to exit the eddy and there will be an updraft where it sucks up toward the prevailing winds.
In places like yours, wind speed is a critical ingredient. Prevailing wind direction comes into play, but
speed will have as much, or more, influence on what the surface wind is actually doing.
You need to get in there during the off season and do some wind studies. Do it under as many different conditions as you can. Use milkweed. You'll find predictable patterns.
