I was always looking for hot days with a south wind to bring in the perch. Now, I think I need to wish for north winds, to blow the cooler waters towards the shore. This will change the thermocline bringing the perch in. Right now, they seem to be way out. 52 to 56 fow. Need them to get a bit closer. Am I thinking right? After we change the thermocline, we may hope again for south winds? Please educate me.
