Cold water makes redfish look for something warmer.
Here in the Golden Isles,on those bluebird days of winter,Redfish will be out roaming around looking for a warm place in the sun and something to eat. Probably the same thing your doing around Lunchtime on one of these days. Target Reds on low tide in the middle part of the day. You'll find them either in the middle of or in the back of creeks that have mud flats and or oyster beds that are warmed by the sun and hold bait. LIve bait is best ,but artificials will produce also.
