Fishing Florida Keys

The Florida Keys fish differently than the cold water coasts, and the chart reflects that. Here the story is the edge of the Gulf Stream and the deep blue water that runs close to the reef line. The reef drops off quickly into deep water, and the warm Gulf Stream and its eddies spin color changes, current edges and temperature breaks within an easy run of the islands. You are looking less for a cold upwelling seam and more for the weed lines, the color changes and the temperature edges that set up where the blue water meets greener or cooler water near the reef and the Stream edge.

Structure still matters. The reef line, the humps and the deep drop offs concentrate bait, and a color or temperature edge sitting over that structure is where the pelagics hunt. Current is a big part of the picture here, which is why pairing the SST and chlorophyll layers with the depth contours helps you find the spot where the warm water, the edge and the bottom all line up.

Seasonally the Keys offer something close to year round offshore fishing. Dolphin, known elsewhere as mahi, run in the warmer months and are a classic blue water weed line target. Sailfish and kingfish show in the cooler months, wahoo and tuna move through, and the reef and wreck fishing runs all year. Seasons, runs and regulations change, so none of it is a promise, but the habit of reading the color and temperature edge against the Stream and the reef is the constant.

Before you run, line up the color change and the temperature edge against the reef drop and the current, and point the bow at the edge that has all three working together.

What you get with ReelTemps

I've tried every temp map out there and they all feel like they were built ten years ago. I'm not exactly a tech guy, but this one actually makes sense the second you open it. First time using it, I marked a break in about 30 seconds the night before and boated bluefin right on it the next morning.

Used to burn half a tank driving around looking for color change or a solid temp break. Now I check ReelTemps before I leave the dock and I know exactly where I'm going. Less time driving around guessing, more time with lines in the water.

Albacore season used to mean a couple hours of homework the night before and just hoping it held up. Now I do most of my research that morning and pull it up on my phone if things change once we're out there. Makes calling an audible a lot easier.

Florida Keys FAQ

What edge am I looking for in the Keys?
Usually the color change and temperature edge where the warm blue Gulf Stream water meets greener or cooler water near the reef line, often marked by weed lines. It is less about cold upwelling and more about the Stream edge and current.
How close is the good water to the islands?
The reef drops off into deep water quickly, so the blue water and the Stream edge can be a short run from the Keys. The chart shows where the edge is sitting so you are not running past it or stopping short.
What runs here and when?
Dolphin (mahi) in the warmer months on the weed lines, sailfish and kingfish in the cooler months, with wahoo and tuna moving through and year round reef and wreck fishing. Always check current seasons and regulations.
Are there buoys to ground truth the temperature?
Where NOAA buoys are present nearby they are shown with their latest readings, so you can compare the satellite SST to a real in water measurement. Satellite and in water readings can still differ.
