Biscayne Bay is the place to go for Bonefish in the area I cover. Bonefish are available all year round. Winter months (November through March) can be more challenging but the fish you find are typically larger. April through October fish are in their summer pattern, fish them early in the day before it gets too hot. In summer fish run smaller on average but you'll see more. The average Bonefish in Biscayne Bay is approximately 7lbs, so these are all nice fish.
