Now, Miami flats fishing season, what can you expect during the year? So, let us find out.
One of the most productive yet most underrated times to fish flats in Miami is during winter. Water temperatures drop, and the bay clarity becomes better during this period. Cold fronts decrease algae blooms, making it ideal to sight fish.
It is an excellent time to pursue big bonefish. These fish venture into shallow water to feed, particularly on sunny afternoons when the water temperatures are a little higher. Cruising the flats may also find barracuda and shark, jacks, and the occasional permit.
Fishing in Biscayne Bay during the wintertime will offer anglers calm waters and a reduction in boat traffic, which makes it a peaceful beauty to enjoy.
The most recommended period to attempt flats fishing in Miami is during spring. With the warming of the water temperatures, all the major species, including the bonefish, tarpon, and permit, are active and more prevalent.
March and April, Bonefish can be found traveling in schools throughout the flats, and permit start appearing near shallow wrecks and channels. Tarpon also come in full force, getting ready to make their annual migration.
It is a season with reliable action and a chance to catch trophy-sized fish. Fly rods or light spinning tackle anglers will find this period of the year to be favorable for sight casting in shallow water.
Summer is known for hot weather and explosive fishing. June through August is the top time to target permit in Biscayne Bay. These powerful fish and push onto the flats during the right tides.

Fall is a transitional season with plenty of opportunity. As water temperatures begin to drop, fish feed more aggressively to prepare for winter. You can catch a mix of species during this time, including bonefish, tarpon, permit, and barracuda.
Wind and weather conditions can vary more than other times of year, but there are still plenty of calm days ideal for flats fishing. September and October are especially good months to find hungry bonefish tailing on the flats during low-light conditions.
Fall is also a great time for those who want a quiet, less-crowded experience on the water.
In addition to choosing the right month, pay attention to moon phases and tides. New and full moons typically bring larger tidal swings, which can improve your chances of spotting fish on the move. Flats fishing is especially productive during incoming and outgoing tides when fish are more likely to feed.
