Hi Mr. Sadlak,
You can catch redfish consistently year round. This time of year, rivers, canals and all the backwater areas thrive with Redfish. Docks are a great place to find Redfish at this time of year too. They are also on oyster bars, mangroves and grass flats.
Learning and fishing the tides is important, but it is even more important to learn the structure they are on during the various seasons. Fall is probably the best and most consistent Redfish bite anywhere throughout the state. Starting around the end of August, and very strong during September and October, big schools will gather up. You will find them on grass flats, oyster bars and they will be easy to spot and locate.
Be persistent and you will find the Redfish. Move around different flats and look for schools of fish. Once you find a school or two and catch a few, take some mental notes - you just discovered yourself a pattern.
Many anglers will tell you flats with mullet schools are the best. In my experience I have found schools of mullet, yet still did not find many Redfish. That said, I will tell you that a flat that is null and void of mullet, usually has no Redfish. Flats alive with active mullet and baitfish is always a good sign.
In the fall I would concentrate my red fishing in and around San Carlos Bay flats. I would suggest places like Merwin Key, Big Island, Fisherman Key and all the other little key and Islands in that area. I would even check that area now, since we have had a warm winter so far. If you don’t find or catch any Redfish in these areas, I would move up inside Caloosahatchee River and start fishing some mangrove shorelines, oyster bars and docks.
During the winter low tides, Redfish will lay up in the only place that holds water, sometimes making for a phenomenal day of fishing. These very low tides will occur before and after the new and full moons.
