The evening bite is almost always a good feeding time for spotted bass.  It doesn’t matter if it is spring, summer or fall.  When the water temperatures are cooler, the evening bite can be much better as the warm sun warms up the day through the afternoon.  You might think that with that logic, the morning bite in the hot weather would be better than the evening bite because the water temperatures will be lower in the morning.  That may actually be the case at times, however, the sun setting triggers bass to feed, so you will always get that peak feeding time by fishing in the evening.
