Winter in northern Florida can be cold.
Winter in northern Florida can be cold. We have cold conditions at least compared to Miami. The water temperatures are usually in the 50s but mid-40s are not unheard of. Redfish preferred range is 70° to 90° so where do they go when temperatures are below this range. Redfish do not migrate to avoid cold water but do go deep to find more stable temperatures.
Water that floods the flats and shallow creeks will warm during a sunny day. This is because the exposed creek bottom and mud flats will absorb heat when it is sunny. When the tide raises the incoming water is warmed by the warm sand and mud. When the tide drops this water flows out of the flats and creeks. This presents three opportunities to locate and catch redfish. Fish the creek or flats entrance as the tide rises. Fish will follow the rising tide as it enters these areas. Fish the shallow creeks and flats after they are flooded. The exit from the creek or flat is another hot spot as the tide falls.
If it is a cold day without sun try fishing the deep water at the entrance to the flats or creek. Fish will hold along the edge of the deepest water waiting for the sun to do its job. Redfish are predictable in their search for warmer water and bait to eat. If you can intercept their daily movement you will catch them.
Fish with Gulp Swimming Mullet on 1/4 or 1/8th-ounce jighead or minnow imitation hard baits. Mud minnows, shrimp and small crabs if you prefer live bait. Keep your presentation slow because the cold water slows the actions of both the redfish and their prey.
