I would fish the wind blown banks since they will be more oxygenated, have more available baitfish, and the stained water warms up faster.

You are thinking right on fishing the North end as long as there is plenty of shallow water to warm up near the backs of the coves. In most lakes this is where the muddy water will be coming in. As you leave the main lake and head north up the main river or large creeks that feed the lake look for coves off of that northern route that run to the west or as near west as possible. The back half of these coves will be a lot clearer.

Most of the time the wind is blowing out of the south east and will keep pushing the water that has warmed up back into the cove. Any north winds that come with a front will not affect these coves as much and makes it more difficult to push the warm surface water out of the cove.

On big lakes there can be as much as 5 degrees difference in surface water temp. from a cove down by the dam and one up North that runs to the West. A dog leg cove that breaks to the South is even better.
