There are a multitude of factors that determine when is the best time of day to fish.

The biology of the species you wish to target plays a large role in when you want to fish. As a general rule, most predatory fish (in fresh and saltwater) are usually active during crepuscular (low light) periods of early morning and evening. This is partly because the predator's have better vision during these periods than baitfish. However, there are exceptions to the rule. When I lived in south Florida, I frequently fished for peacock bass, and they always bit best during the hottest, brightest part of the day.

Depending on the time of year, different times of the day may be more productive than other times. This is especially true with bodies of water that have high amounts of boat traffic during the summer.

However, the best answer in regards to the best time of day to fish is whenever you have time to go, like Chris per said. Fish will always surprise you. I have had great days during times that were considered less than optimal.
