Jig head weight can make all the difference in summer !
The lake I fished had water over 84 degrees and a surface layer of bright green algae. The shallows were the place to start after seeing the surface activity in 3' in the shade of overhanging limbs. At first I was was using 1/16 oz ball head jigs and different plastic designs, but though nipped many times, no hook-ups. Fishing in that type of water, shallow (less than 5') has always required going to a 1/32 oz jig that allows a bit slower retrieve. Doing so made all the difference and pan fish and a few bass slammed lures all afternoon in the hot sun from 12pm-5pm. Total caught between bass, sunfish, crappie and y.perch - 48 fish.

When I started fishing in water over 5', I went back to the 1/16 oz because with long distance casts and that much line in the water allows for a slow lure motion so important in hot or cold water. I experimented with eight designs and caught fish on all - even those I didn't have confidence in such as curl tail and rat tail grubs.
Note: curl tail grubs always have a much slower rate of retrieve because the the curl tail's resistance to rod tip or reel handle speed changes which seem to be less effective than for straight tail grubs.
I have a new appreciation of Leland's Crappie Magnet grubs which easily caught ten fish in one area of different species. (pictured under the photo of a finesse worm tail cut to 1.5".)
