Trip Summary
Tarpon fishing in Key West in August can be great. While the peak tarpon migration generally occurs from March to July, many resident tarpon remain in the area throughout the Summer and Fall. These fish range from 5 to 50 pounds. They can be found in backcountry channels, near mangroves and nearshore flats both Atlantic and gulf side. The calm, warm waters of August provide ideal conditions for both fly fishing and artificial lures, especially during early morning or late evening when the heat is less intense and the fish are more active. But they can be caught all day long. This time of year generally sees less pressured fishing, as the spring and summer visitor crowds begin to thin out. Night fishing is also always a great option . August offers a unique opportunity to target resident tarpon in Key West and the Lower Keys.
