Q.SST & Offshore Fishing
How does the Gulf Stream affect offshore fishing?
A.
The Gulf Stream brings warm tropical water (78-84°F) up the East Coast, creating a warm-water highway that mahi, marlin, sailfish, wahoo, and tuna follow seasonally. The Stream's western edge (where it meets cooler shelf water) is one of the most productive offshore fishing zones in the world.
The Stream's distance from shore varies — sometimes within 15 miles of Cape Hatteras, sometimes 50+ miles offshore. SST satellite imagery shows the daily edge. SST threshold pages cover species ranges aligned with Stream temperatures.
