Why December is Prime Time for Fly Fishing in the Florida Keys

Fly fishing in the Florida Keys in December offers a unique blend of ideal conditions and exciting opportunities, making it a favorite among anglers. The weather itself is a major draw. Gone are the scorching summer days and the threat of hurricanes. December brings milder temperatures, with average highs in the low 70s to upper 70s Fahrenheit (around 21-26 Celsius). This comfortable climate is perfect for spending long hours on the water. The humidity also drops, making the experience even more pleasant. The winds, which can be a factor in any Keys fishing trip, tend to be more manageable in December, creating more days where fishing is possible, especially on the flats. You'll find a lot of sunny days and light breezes which make sight-fishing for bonefish, permit, and tarpon a lot easier. And with the peak tourist season still a little ways off, you won't have to compete with as many boats on the water, giving you more space and freedom to cast your line. The combination of these factors makes December a top choice for serious fly anglers. The fish, especially those that love cooler water, are more active and feeding aggressively, increasing your chances of landing a trophy. So, if you're looking for a comfortable, productive, and less crowded fly-fishing experience, December in the Florida Keys should be at the top of your list.

The Allure of Cooler Weather and Water

The shift in weather patterns during December has a direct impact on fish behavior. As the water temperatures cool down, species like bonefish and permit, which thrive in specific temperature ranges, become more active. They tend to move into shallower waters, making them easier to target on the flats. This creates exceptional sight-fishing opportunities, where you can spot the fish and cast directly to them. This method is incredibly exciting! The cooler water also increases the fish's metabolism, causing them to feed more aggressively. They are more likely to chase flies and take a well-presented offering. The combination of increased activity and accessibility makes December an ideal time to target these prized game fish. For tarpon, the cooler temperatures can also concentrate them in certain areas, particularly around channels and passes, as they seek warmer pockets of water. This can lead to some incredible fishing opportunities. It's a time when you have a good chance to hook into some truly monster fish. For any fly fisher, the opportunity to battle these powerful species in a beautiful setting is an experience that will stay with you forever. That’s why fly fishing the Florida Keys in December is so popular. It really sets the stage for a memorable fishing adventure.

Less Crowds, More Opportunities

One of the biggest advantages of fly fishing in the Florida Keys in December is the reduced number of anglers on the water. Compared to the peak season in spring and summer, December offers a more relaxed and less competitive fishing environment. Fewer boats on the flats mean less pressure on the fish, making them less wary and more likely to eat your fly. It also means you'll have more space to cast and maneuver your boat, which is especially important when sight-fishing. Finding your dream spot on the flats becomes easier. You won't have to worry about bumping elbows with other anglers or waiting for your turn to fish a specific area. This allows you to explore different locations and target various species without feeling rushed. A less crowded environment enhances the overall fishing experience, making it more enjoyable and allowing you to focus on the thrill of the catch. Booking accommodations and guides is also easier and often more affordable in December. You might find better deals on lodging, boat rentals, and guided trips, making your fishing vacation more budget-friendly. All these factors combine to create a more exclusive and rewarding experience. This is especially true for those seeking a more personal and intimate fishing adventure. The tranquility and focus you gain from fewer crowds allow you to hone your skills and fully appreciate the beauty of the Florida Keys.

Target Species: What You Can Catch in December

December in the Florida Keys is a smorgasbord of opportunities for fly anglers, offering a diverse array of species to target. While the specific species activity can vary depending on the weather and location, several key species consistently provide exciting fishing action throughout the month. Let's explore some of the most popular and sought-after species you can expect to encounter while fly fishing in the Florida Keys in December.

Bonefish: The Grey Ghosts

Bonefish are a prime target for fly anglers in the Florida Keys, and December is an excellent time to chase them. These “grey ghosts” are known for their blistering runs and challenging fights, making them a thrilling catch. In December, bonefish tend to move into shallower flats, where they feed on crustaceans and other small organisms. Sight-fishing for bonefish is one of the most exciting aspects of fly fishing, requiring anglers to spot the fish in the clear, shallow water and make a precise cast in its path. Using a flats boat or wading in appropriate areas allows anglers to get close to these elusive fish. They usually reach around 19 inches (48 cm) and can weigh up to 5 pounds (2.3 kg), but larger bonefish are possible. Look for bonefish on the flats around Islamorada, Key Largo, and the backcountry areas of the Everglades National Park. The key to success is patience, stealth, and a well-presented fly. Popular fly patterns for bonefish in December include Gotchas, Crazy Charlies, and bonefish bitters. These flies are designed to mimic the crabs, shrimp, and other small creatures that bonefish feed on.

Permit: The Holy Grail

Permit are the ultimate prize for many fly anglers, and December offers a good chance to hook into these challenging fish. Known for their intelligence and selective feeding habits, permit present a true test of angling skill. In December, permit can be found on shallow flats, along channels, and around wrecks, often feeding on crabs and other crustaceans. Catching a permit on a fly is a significant achievement and a moment you won’t forget. The size varies, but permit can grow to be massive, sometimes exceeding 30 pounds (13.6 kg). Success in permit fishing requires accurate casting, the ability to read the water, and selecting the right fly pattern. Crab imitations, such as the Del Brown Merkin or the Avalon fly, are popular choices. It's best to fish near Marathon, Big Pine Key, and the waters around the Marquesas Keys. The waters there are known for holding permit. Be prepared for a long battle! Permit are strong and will test your tackle and skills.

Tarpon: The Silver King

Although the peak tarpon season may have passed, December can still offer opportunities to target these magnificent fish. Tarpon are a thrill to catch, known for their spectacular jumps and powerful runs. In December, tarpon often congregate in channels, passes, and near the deeper cuts, seeking warmer waters. They can also be found in the backcountry and near the Everglades. Target these fish using sinking lines and large streamer flies. Sizes range widely, but tarpon can grow to be enormous, sometimes exceeding 200 pounds (90 kg). If you are lucky enough to encounter tarpon in December, be prepared for an intense fight! They can take you on a long run, requiring skill and endurance. Popular fly patterns for tarpon include black or purple streamers, as well as baitfish imitations. Try fishing around the bridges, channels, and deeper waters of the Keys for a chance to hook into a tarpon during December.

Essential Gear and Tackle for December Fly Fishing

To ensure a successful and enjoyable fly fishing trip to the Florida Keys in December, it's crucial to have the right gear and tackle. The specific equipment you'll need will depend on the species you're targeting, but here's a general overview of the essential items. This will ensure you're well-equipped for various conditions and species you might encounter.

Fly Rods and Reels

The choice of fly rod and reel is critical for any fly-fishing adventure. For bonefish and permit, a 9-foot, 8-weight fly rod is a versatile option. This rod weight provides enough power to cast accurately in the wind and fight larger fish. Pair this rod with a high-quality reel with a smooth drag system and a good amount of backing. This ensures you can handle the blistering runs of bonefish and the tough fights of permit. For tarpon, a 10- or 11-weight rod is recommended. These heavier rods offer the necessary strength to cast large flies and battle powerful fish. Again, a reel with a strong drag is essential when targeting tarpon, as these fish are known for their long, blistering runs. Make sure your reel can hold plenty of backing to deal with those long runs. When choosing a reel, consider saltwater-rated reels with corrosion-resistant components. This will ensure they stand up to the harsh saltwater environment. And of course, keep those reels regularly maintained to keep them in good working order.

Fly Lines and Leaders

Selecting the right fly line and leaders is also vital for success. For bonefish and permit, a weight-forward floating fly line designed for saltwater use is a good choice. These lines offer excellent casting distance and presentation, which is essential for sight-fishing on the flats. Use a tapered leader of 9 to 12 feet long, with a tippet strength of 12 to 16 pounds for bonefish. For permit, you may need to increase the tippet strength to 16 to 20 pounds, depending on the size of the fish and the conditions. For tarpon, you'll need a floating or intermediate fly line, depending on the fishing conditions. Use a leader of 8 to 10 feet long, with a tippet strength of 60 to 80 pounds, to handle the powerful strikes and runs of tarpon. Fluorocarbon tippet material is a great choice as it is nearly invisible underwater and resists abrasion. Always check your leader and tippet for wear and replace them as needed.

Flies and Other Accessories

Having the right flies is, of course, essential. For bonefish, carry a selection of Gotchas, Crazy Charlies, and other crab and shrimp imitations in sizes 4 to 8. For permit, stock up on crab patterns, such as Del Brown Merkins, Avalon flies, and other crab imitations in sizes 2 to 1/0. For tarpon, carry a variety of large streamer flies in black, purple, and chartreuse, in sizes 2/0 to 4/0. Also bring a good selection of saltwater-rated hooks and plenty of fly-tying materials if you plan to tie your own flies. In addition to flies, you'll need a few essential accessories. These include a good pair of polarized sunglasses to reduce glare and help you spot fish, a hat for sun protection, and appropriate clothing to keep you comfortable. Consider a wading belt, wading boots, a stripping basket, and a net, all of which will make your fishing experience more enjoyable and effective. Also, don't forget essential tools like pliers, line cutters, and a hook sharpener. A wading staff is also handy if you plan to wade fish. With the right gear and tackle, you'll be ready for any fly-fishing challenge the Florida Keys throws your way in December.

Where to Go Fly Fishing in the Florida Keys in December

The Florida Keys offer a variety of locations for fly fishing in December, each with unique characteristics and fishing opportunities. Here are some of the best spots to consider:

Key Largo

Key Largo is the northernmost key and offers excellent access to both the Atlantic Ocean and Florida Bay. The flats around Key Largo are known for bonefish and permit, especially during December. The channels and deeper waters provide opportunities for tarpon, even in December. Key Largo has a lot of experienced guides and outfitters who can help you find the best fishing spots and navigate the local waters. Consider booking a flats boat or backcountry charter to explore the numerous flats and shallow-water areas. You can also explore the backcountry of the Everglades National Park from Key Largo. This area offers a unique fishing experience, with opportunities for snook, redfish, and other species, in addition to tarpon and permit. Many of the channels and creeks offer good protection from the wind, making them ideal for fly fishing in less-than-ideal weather. Key Largo provides a great starting point for your December fly fishing adventure.

Islamorada

Islamorada is often called the
