The recent cold front that moved through South Florida and much of the southeastern United States caused a noticeable drop in the surrounding water temperatures.
As cooler water moves into the region, many warm-water species travel farther south. This seasonal movement often leads to excellent winter fishing throughout the Florida Keys.
Some of the migratory fish that commonly arrive in greater numbers during the winter include:
- King mackerel
- Spanish mackerel
- Sailfish
- Cobia
- Pompano
- Blackfin tuna
The change in temperature can create productive fishing conditions both along the reef edge and offshore.
Look for Gulf Stream Temperature Breaks
One of the best ways to find fish during the winter is to locate the edge of the Gulf Stream.
The warm Gulf Stream current often meets the cooler, shallower water surrounding the Florida Keys. This difference can create current edges, temperature breaks, and changes in water color that attract baitfish and feeding predators.
These areas can be especially productive when targeting:
- Sailfish
- Blackfin tuna
- Kingfish
- Mahi-mahi
Keeping a close eye on the approximate location of the Gulf Stream can greatly improve your chances of finding active fish.
Where to Find Sailfish and Mahi
Different species often prefer different parts of the Gulf Stream.
Mahi-mahi generally stay on the warmer side of the current, where they may gather near floating debris, weed lines, or schools of baitfish.
Sailfish often travel close to the edge of the current, especially where warmer blue water meets cooler coastal water. These areas may also feature noticeable color changes, current seams, or concentrations of bait.
Blackfin tuna and king mackerel can also be found around these productive temperature and current breaks.
Check Conditions Before Leaving the Dock
Finding current edges and temperature changes before your fishing trip can save both time and fuel.
Several websites, subscription services, and onboard marine electronics provide information about:
- Sea-surface temperatures
- Gulf Stream location
- Water-color changes
- Current direction
- Temperature breaks
Some services require a subscription, while others provide free satellite data. One free resource we use is Rutgers University’s sea-surface temperature imagery, which uses satellite data to help anglers identify changing offshore conditions.
Reviewing this information before leaving the dock can help you choose a more productive area and spend more time fishing.
Book a Winter Florida Keys Fishing Charter
Cooler weather can create outstanding opportunities to target Atlantic pelagic species in the Florida Keys.
Whether you want to pursue sailfish, blackfin tuna, king mackerel, mahi-mahi, or another seasonal species, winter is an exciting time to get out on the water.
