Best Deep Sea Fishing Fishing Spots in Islamorada
Top spots where local captains target blackfin tuna and other deep sea fishing species.
Islamorada Hump
The Islamorada Hump is a deepwater seamount formation roughly 15-20 miles south of Islamorada where the bottom rises from over 600 feet to around 400 feet. This structure concentrates blackfin tuna, wahoo, mahi-mahi, and swordfish in significant numbers. Deep-dropping for swordfish on the Hump has become a signature Islamorada offshore technique.
Gulf Stream Edge (Islamorada)
The Gulf Stream runs approximately 8-12 miles off Islamorada's reef line, bringing warm bluewater current and pelagic species within easy range. Sailfish, mahi-mahi, wahoo, and blackfin tuna patrol the Stream edges, especially along weed lines and temperature breaks. Islamorada's proximity to the Stream makes it one of the top bluewater destinations in the Keys.
409 Hump
The 409 Hump is a deepwater bottom formation south of Islamorada named for the GPS coordinates, where the ocean floor rises to create a fish-concentrating feature. Blackfin tuna, wahoo, mahi-mahi, and swordfish gather around this structure in deep water. It is a key waypoint for Islamorada offshore captains targeting pelagic species and deep-drop swordfish.
Tennessee Reef (Deep Edge)
The deep outer edge of Tennessee Reef drops from 60 feet to hundreds of feet along the reef wall southeast of Islamorada. Mutton snapper, black grouper, yellowtail snapper, and cubera snapper hold on the deep reef ledges. Sailfish and kingfish troll along the reef edge, making it productive for both bottom fishing and trolling.
