Key West Pro Guides Fishing Report – December 2025

Surface Temp: Stable seasonal winter pattern

Water Conditions: Clear, consistent

Region: Key West, FL

Guide Team: Key West Pro Guides (full-time owner/operator captains)

December rolled in with calm weather, steady temperatures, and one of the strongest bait supplies we've seen in years. With zero hurricane disruption this season, water temps stayed consistent, and the pilchards have been thick—fueling a fantastic run of winter action.

From the backcountry to offshore, December is a transition month, shifting us into cooler-water species while still offering tons of light-tackle opportunity for visiting anglers.

Offshore & Deep Sea Bite

Winter patterns are now taking hold offshore, bringing in the explosive cold-water species that make December such a fun month.

Kingfish (Smokers)

December is the kickoff for big Kingfish, and the first wave of true “smokers” has already shown. They’re holding well offshore with occasional pushes toward the reef line.

The Mackerel Family Is Thick

Cero and Spanish Mackerel are here in force—big numbers and good size. Great action for anyone who enjoys steady light-tackle bites.

Blackfin Tuna

December remains prime time for Blackfin Tuna, one of the most action-packed bites of winter. When a school lights up on the surface, it’s full chaos in the best way—fast retrieves, drag screaming, nonstop fun.

Wahoo on the Rise

Wahoo action jumps in December, and fish over 50 lbs aren’t unusual this time of year. They’re fast, powerful, and some of the best eating fish in the ocean.

Sailfish Building

The Sailfish bite continues improving heading into January, which kicks off the peak stretch lasting through early spring.

Mahi (Dolphin) Fading, But Not Gone

Most Mahi migrate out with the cooler water, so think of them as a bonus fish this month. We still see surprise flurries pop up on warm days.

Barracuda

Large Barracuda are active and aggressive in December—excellent targets for sight-casting or high-speed action.

Trip Tip: For offshore runs, we strongly recommend at least a 3/4-day this month to keep travel time from cutting into fishing time. That’s especially true for groups of three or four anglers.

Backcountry & Nearshore Notes

Stable, cooler temperatures mean consistent shallow-water fishing. Morning trips tend to be most productive for anglers wanting to work the basins, channels, and flats. (Backcountry trips are a signature Key West Pro Guides experience .)

Afternoon backcountry trips remain great for families, kids, or anyone who wants calm water and steady action without pushing long distances.

Patch reef fishing is also a strong option in the afternoons, with a good variety.

Sharks continue to be active and plentiful—an absolute blast on light tackle and something most guests can’t experience back home.
