Temperature difference in the sun and shade

[NCYankee]

How much do think the difference in water temperature will be between two spots where one is in the direct sunlight most of the day and the other is in the shade the whole day? The temperature is forecasted to be highs of 55-60 and lows of 30-40 with plenty of sun except for one day (rain) for the next week. Temperatures have been about 10 degrees cooler the last week or so.

I fished a sunny spot recently and caught a 5lber on 11/24 (spinner) and a 4lber on 12/1 (lipless crank.) The sunny spot I've been fishing is the area around the cove enclosed in red at the top of the picture. The blue line is approximately where the creek channel runs.

The southern part of the lake is in the shade the whole day due to the position of the sun. I haven't fished the area enclosed in red at the bottom of the picture before because it takes over twice as long to hike to as the other spot. However, there are large rocks off the point and laydowns in that area that aren't visible on this aerial photo.

If you think I should fish the shaded spot, what do you think I should use? I was thinking a black/blue jig n pig, green/brown craw jig, a t-rigged watermelon seed fluke, and a rattlin lipless crank.
