There are many conditions considered in calling a day unfishable in Louisiana. Some of the basics include wind, water height and clarity, air temperature, and lightning. A day can be cloudy with 20 knot winds and produce high floating aggressive bulls ripe for the picking. Louisiana may have small tides but they can play a key role in finding active fish. I prefer a 1.5 foot tide with the low tide value below ( +.5). Sometimes the rotund girls just seem to show up to the dance for no reason whatsoever. However, there are some conditions that just plain stink for the Louisiana marsh.
Wind, the fly fisherman's nemesis. Actually wind can be managed to a certain degree. Large fly rods, like 9 and 10 weight, can handle big wind. Polling downwind gives clients downwind shots. There is a point of huge diminishing returns. Fishing becomes increasingly more difficult when my clothes begin to flap like a flag. This happens around 18-20 knots. At or above 25 knots I begin to loose the ability to pole and direct the boat. Casting with accuracy becomes almost impossible. At winds above 25 knots I generally tuck my tail and head for the launch. Don your gear, this ride will get a little bumpy.
Anyway as for tails from bayou big easy, fly fishing has settled into full a blown winter pattern. Fishing the bull redfish is easy when the big easy gets a break from this abnormally severe weather pattern. Lately I am finding the schools of bull redfish much closer to the mash banks. Any nice flat with shallow still water seems to hold sunbathing 10-15 pound fish. Since they are inactive sitting on bottom try polling in a zig zag pattern. This will stir the fish up. Some fish will want to come back to the same holding spot. Easy pickings for a good caster like you. Come on down I'll show ya.
