I've heard that phrase before, too...and it might apply to freshwater. But down here in our marsh, a west wind is the kiss of death; it tends to blow the clean, salty water out of the marsh and replace it with low, muddy water. Any wind out of the east or southeast is best for us, but that is a peculiarity of geography, with the Mississippi greatly influencing conditions.when the wind is from the east, fishing is least. when the wind is from the west, fishing is best"
Generally, the fish turn on before a front moves through, and afterwards, they tend to clam up.
