Most bodies of water provide a very good morning bite for smallmouth bass.  At times, the bite can be incredible with anglers catching a limit of bass in 10 casts or less if you know where they feed.  During the early spring or late fall, the morning bite is usually not as good as it is during the warmer months.  If the water is above the mid-50s, you can count on a good morning bite.  In cooler water, the bite may actually be better as the sun comes out and warms up the water a couple of degrees.
