December to February. Cold-water trout fishing, and it is better than its reputation. When a front drops the temperature, speckled trout stack into the deeper holes and channels of the Back Bay and the bayous, and a guide who knows those holes can have a very good morning while the beach road is empty. Dress for wind off the water, which makes fifty degrees feel like forty.
March to May. The best all-round window. Water warming, trout spreading out over the grass and shell, redfish working the marsh edges, sheepshead thick around every piling before they move off. Mild air, low humidity and the calmest mornings of the year. If you are choosing when to come specifically to fish, come now.
June to August. Hot, and the fishing moves to the edges of the day. Early morning and the last two hours of light are worth having; the middle of the day in ninety-degree heat with a thunderstorm building inland is not. This is also when nearshore trips around the islands come into their own, with Spanish mackerel and bluefish in the passes.
September to November. September is the statistical peak of hurricane season on this coast and trips cancel. It is also, once a front or two has been through, the start of the best redfish weeks of the year, when bull reds push into the passes and around the islands. October is quietly the nicest month on the Mississippi coast for anything done outdoors.
