I've been fishing Kaw lake and some lakes in Arkansas for more years than I want to say. Without a doubt, wind - weather systems have a big effect on shallow water crappie during the spawn. As far as wintertime fishing, it doesn't seem to have the effect on the deeper water fish. I have caught as many in a north or east wind as I have fishing with south wind in deep water. I pay a lot more attention to the weather when fishing shallow in the spring. Without a doubt, wind is a big inconvenience for fisherman. I think what's affecting the fish now is a 10 degree rise in water temp the last few days. The fish moved up in the water column and somewhat scattered and you tend to fish below them and with crappie that's not gonna work.
