Slack tides usually lead to tough fishing for inshore fish. With sheepshead, the slack tide that occurs at the peak of the high tide can offer some excellent fishing. The slack tide may last anywhere from 30 minutes to several hours depending on the location and the time of year. The bite will usually stay good during this slack tide and then it tends to pick up as the water starts moving out again. Some of the better areas to fish during the high tide are mangrove-lined shorelines, docks, bridges, jetties and piers.
