In the warmer months of summer fishing in the morning or evening will prove more productive, because the fish bite was more active do to cooler water temperatures and a higher dissolved oxygen content. The opposite will apply when the winter is here and the water is colder. You can fish when the sun is up and the water warms more to a comfortable water temperature for the fish.
Also areas like dark mud bottoms, seawalls, deeper water will hold the heat and keep the water warmer. These are the places that you should be seeking out. Since there is no tidal flow and no chance of warmer water moving in and out. I find places that do not have a tidal influence, are effected more by major and minor solunar periods and other factors such as water temps, oxygen content and availability of consistent forage.
Baits also change along with water temps and winter conditions. Smaller and slower moving baits do well. Crustaceans like crab and shrimp, dead sticking cut baits like ladyfish, mullet pinfish etc... also are effective. Smaller leader and hooks. If your using artificials slower is better and downsize the baits also.
