Florida Keys Fishing in October: What’s Biting and Where

October can be an underrated month to fish the Florida Keys.

Summer is winding down. Water temperatures are beginning their gradual fall transition. Mahi-mahi can still be around offshore, bonefish remain an option on the flats, snapper fishing continues around reefs, and cooler-season species start becoming more interesting as the month progresses.

You also have plenty of ways to fish.

You can head offshore, fish the reef, explore the backcountry, sight-fish shallow flats or leave the boat behind and fish from a bridge.

Here’s what you should know before planning a Florida Keys fishing trip in October.

What Fish Are Biting in the Florida Keys in October?

October anglers may have opportunities for:

• Mahi-mahi
• Blackfin tuna
• Yellowtail snapper
• Mutton snapper
• Bonefish
• Barracuda
• Cero mackerel
• King mackerel
• Wahoo
• Sailfish
• Permit
• Tarpon
• Sharks

Exactly what you’ll find depends on water temperature, currents, bait, weather and which part of the Keys you’re fishing.

October is especially interesting because it’s a transition month.

Early October can still feel a lot like summer.

Later October can begin showing signs of the cooler fishing patterns associated with November and winter.

That gives anglers a lot of possibilities.

Is October a Good Month to Fish the Florida Keys?

Yes.

One of October’s biggest strengths is variety.

If offshore conditions cooperate, you can hunt mahi, tuna and other pelagic species.

If you’d rather stay closer to land, reefs provide opportunities for snapper and other fish.

Flats anglers can look for bonefish and permit.

Backcountry anglers have another completely different set of possibilities.

And anglers without a boat can fish bridges, piers and other accessible locations.

October is also outside the peak summer vacation period.

That can make it an appealing month for someone who wants a fishing vacation without scheduling around the busiest summer weeks.

Mahi-Mahi Fishing in October

October is getting late in the traditional Florida Keys mahi season, but that doesn’t necessarily mean mahi fishing is finished.

Mahi-mahi may still be found offshore, particularly when water and current conditions are favorable.

Anglers searching for mahi often look for:

• Weed lines
• Floating debris
• Working birds
• Current edges
• Baitfish
• Temperature changes
• Floating objects holding small fish

Finding one fish can sometimes lead to finding more.

Mahi are often associated with schools, particularly smaller fish.

If mahi are your number-one target, I’d tell the captain that before your trip but remain flexible.

By October, it may make more sense to pursue another species if offshore conditions aren’t producing mahi.

Blackfin Tuna Fishing in October

Blackfin tuna deserve a spot on your October target list.

They’re strong, fast and capable of providing an excellent fight on appropriately sized tackle.

Blackfin can be encountered around offshore structure and areas where bait is concentrated.

Fishing methods can include:

• Trolling
• Live baiting
• Jigging
• Casting
• Chumming

Tuna also offer another offshore possibility when mahi aren’t cooperating.

That’s one reason an October offshore trip can be fun even if you don’t have one specific species in mind.

Wahoo Fishing in October

Wahoo are one of the fish that make cooler-season Florida Keys offshore fishing exciting.

October sits near the transition into the time of year when more anglers start paying attention to them.

Wahoo are built for speed.

Hook one and you’ll quickly find out why they’re such a prized offshore fish.

Common techniques can include trolling lures and rigged baits at various speeds.

Wahoo have extremely sharp teeth, so appropriate tackle is important.

If catching a wahoo is high on your fishing bucket list, late fall and winter may offer stronger opportunities than early October, but October is when I’d start paying attention.

Sailfish in October

October can also mark the beginning of increasing interest in sailfish.

Florida Keys sailfishing is closely associated with the cooler months.

Changes in weather, currents and concentrations of bait can affect how productive the fishing becomes.

Sailfish may be targeted with:

• Live bait
• Kite fishing
• Trolling
• Drift fishing

A sailfish is one of those catches that can turn an ordinary vacation into a story you’ll tell for years.

If that’s your primary goal, talk to a captain who spends a lot of time specifically targeting sailfish rather than booking a general offshore trip.

Cero Mackerel Fishing in October

Cero mackerel don’t always get as much attention as mahi, tarpon or sailfish, but they’re worth knowing about.

October begins a productive part of the calendar for cero mackerel in the Florida Keys.

These fast-moving predators can be found around reefs and other areas holding bait.

They’ll hit live bait and artificial lures and can be a lot of fun on relatively light tackle.

For someone who mostly wants action rather than a specific trophy species, cero mackerel can be a welcome addition to an October fishing trip.

King Mackerel Fishing in October

King mackerel, usually called kingfish, begin becoming more relevant as the Florida Keys move toward cooler weather.

Kings are fast, aggressive predators.

They’re frequently targeted around:

• Reefs
• Wrecks
• Current edges
• Areas holding baitfish
• Offshore structure

Trolling and slow-trolling live bait are common techniques.

Don’t underestimate them.

A good kingfish can peel line off a reel in a hurry.

Yellowtail Snapper Fishing in October

If your main goal is catching fish rather than hunting one specific offshore trophy, reef fishing deserves a close look.

Yellowtail snapper are one of the signature reef fish of the Florida Keys.

They’re popular for several reasons.

They can provide good action.

They’re fun on lighter tackle.

And legal fish make excellent table fare.

A typical approach involves anchoring around productive reef structure, establishing a chum line and drifting small baits naturally back toward feeding fish.

Clear water can make yellowtails cautious.

Leader size and presentation can matter quite a bit.

Mutton Snapper Fishing in October

Mutton snapper give October reef and wreck anglers another possibility.

They’re larger than many of the yellowtails commonly caught around Keys reefs and can put up an impressive fight.

Look for them around:

• Reefs
• Wrecks
• Rocky bottom
• Drop-offs
• Other structure

Live bait, cut bait and various bottom-fishing techniques may all be used.

Mutton fishing can require patience.

But one good fish can make the entire trip worthwhile.

Bonefish in October

October can still be a good month to chase one of the Florida Keys’ most famous flats species.

Bonefish.

Bonefish are not huge compared with offshore gamefish.

They don’t need to be.

Hook one in skinny water and you’ll understand the obsession.

They’re fast, wary and difficult to approach.

Anglers typically sight-fish for them on shallow flats using spinning gear or fly tackle.

You’ll often spend more time looking for fish than actually casting.

That’s part of the experience.

If you enjoy hunting fish rather than waiting for them to come to you, bonefishing can be addictive.

Permit Fishing in October

Permit can still be part of the October picture, although the peak warm-season period is beginning to pass.

These notoriously difficult fish can be found around flats, channels, wrecks and deeper structure.

Crabs are one of the classic permit baits.

Artificial lures and flies can also be used.

Permit have a well-earned reputation for following a bait all the way to the boat and then deciding they’re not interested.

Landing one makes all that frustration worth it.

If permit are your primary goal, look for a captain who specializes in flats or permit fishing.

Tarpon Fishing in October

October is well outside the famous spring tarpon migration.

That doesn’t mean there aren’t any tarpon in the Florida Keys.

Resident tarpon can remain in the area and may be encountered around:

• Bridges
• Channels
• Harbors
• Backcountry areas
• Shorelines
• Areas holding bait

If catching a huge migrating tarpon is your dream, I’d build the trip around the spring season instead.

If you’re already visiting in October, asking a local guide whether tarpon opportunities exist is completely reasonable.

Florida tarpon fishing is primarily catch and release, so familiarize yourself with current handling rules before targeting them.

Reef Fishing in October

Reef fishing may be one of the best choices for someone taking their first Florida Keys fishing trip.

Why?

Variety.

You aren’t necessarily putting the entire day into finding one highly mobile offshore species.

Depending on location, conditions and current regulations, your catch might include:

• Yellowtail snapper
• Mutton snapper
• Barracuda
• Mackerel
• Jacks
• Sharks
• Other reef species

Reef trips can also involve shorter runs than offshore trips.

That’s useful for families or anyone who isn’t sure how they’ll handle a long day on the open ocean.

Offshore Fishing in October

October offshore fishing can put several different species in play.

Your captain might be looking for mahi early in the month while also paying attention to tuna, wahoo, kingfish and signs of sailfish activity.

The key word is flexibility.

Going offshore with the attitude that you’ll only be happy if you catch one particular species can unnecessarily limit the trip.

A better question to ask your captain might be:

What’s giving us the best chance of having a good fishing day right now?

The answer could change from one week to the next.

Backcountry Fishing in October

You don’t have to point the boat toward the Atlantic.

The Florida Keys backcountry offers an entirely different fishing experience.

Instead of blue water and offshore trolling, think:

• Mangrove islands
• Shallow flats
• Channels
• Bays
• Calm protected water

Depending on conditions, you may encounter tarpon, barracuda, sharks, snapper and other inshore species.

Backcountry fishing can also provide an alternative when winds make offshore fishing less attractive.

That flexibility can be valuable during fall.

Where Should You Fish in October?

The Florida Keys stretch for more than 100 miles, so where you stay can make a real difference.

Key Largo

Key Largo works well for anglers who want access to reefs, offshore fishing and Florida Bay.

It’s also convenient for travelers coming from Miami and South Florida.

Islamorada

Islamorada gives anglers an impressive variety of choices.

The Atlantic side provides access to reefs and offshore water.

The Florida Bay side gives backcountry and flats anglers an entirely different playground.

That makes Islamorada particularly attractive if you’re planning several fishing days.

Marathon

Marathon puts you near reefs, wrecks, bridges, offshore fishing and Florida Bay.

Its location in the Middle Keys also makes it useful for anglers who want to experience more than one part of the island chain.

Lower Keys

The Lower Keys can be especially appealing to flats and backcountry anglers.

Bonefish, permit, tarpon and other shallow-water species can all be possibilities.

Key West

Key West offers an enormous range of fishing.

Flats.

Reefs.

Wrecks.

Offshore.

You can easily build an entire fishing vacation around Key West without doing the same style of fishing twice.

Florida Keys Bridge Fishing in October

No boat?

No problem.

The Overseas Highway crosses numerous bridges that put shore-based anglers over fishable water.

Depending on the location, you might encounter:

• Snapper
• Barracuda
• Jacks
• Sharks
• Mackerel
• Other species moving through the channels

Moving water often matters around bridges.

Paying attention to tide direction can be more useful than simply showing up at noon because that’s when you happen to have free time.

Always verify that fishing is permitted at the specific bridge or access area before setting up.

Best Baits for October Fishing

There’s no universal October bait.

Match your bait to your target.

Common choices throughout the Keys can include:

• Shrimp
• Pilchards
• Ballyhoo
• Crabs
• Squid
• Cut bait
• Live baitfish

Artificial options can include:

• Jigs
• Plugs
• Trolling lures
• Spoons
• Soft plastics
• Flies

Ask a local tackle shop or charter captain what has been working recently.

Current information can save a lot of wasted fishing time.

October Weather in the Florida Keys

October weather is one reason many anglers like this time of year.

The intense summer heat begins easing as fall moves along.

That can make spending an entire day on the water more comfortable.

You should still expect warm weather and strong sun.

Bring:

• Sunscreen
• Sunglasses
• Hat
• Lightweight sun clothing
• Plenty of water
• Rain protection

There’s another weather issue you can’t ignore.

October Is Still Hurricane Season

Atlantic hurricane season does not end until November 30.

Tropical storms and hurricanes can occur during October.

That doesn’t mean you should avoid booking an October fishing vacation.

It does mean flexibility is smart.

Before making nonrefundable reservations, check:

• Charter cancellation policy
• Hotel cancellation policy
• Travel insurance terms
• Hurricane policies
• Rebooking options

Then monitor the forecast as your trip approaches.

Morning or Afternoon Fishing in October?

There’s no automatic winner.

Morning trips remain popular and offer some advantages.

You can often enjoy cooler temperatures and have the rest of your day available afterward.

But fishing conditions aren’t controlled by the clock alone.

Tides, current, wind and recent fish activity can matter much more.

If your captain recommends leaving at a particular time because of tides or current, listen.

That’s the information you’re paying them for.

Half-Day or Full-Day Charter?

Both can make sense in October.

Choose a Half-Day Trip If:

• You’re fishing with children.
• You’re a first-time angler.
• You’re mostly interested in reef fishing.
• You don’t want fishing to consume your entire vacation day.
• You’re uncertain about seasickness.

Choose a Full-Day Trip If:

• Offshore fishing is your priority.
• You want more time to locate moving fish.
• You’re targeting a specific species.
• Fishing is the main reason for your trip.
• You want the captain to have more flexibility.

Four extra hours can make a substantial difference if the captain needs to run farther to find productive water.

What Should You Bring?

Ask the charter what is already supplied before packing.

Many boats provide rods, reels, tackle and bait.

Items worth considering include:

• Polarized sunglasses
• Sunscreen
• Hat
• Sun-protective shirt
• Light rain jacket
• Non-slip shoes
• Water
• Snacks
• Camera
• Waterproof phone case
• Motion-sickness medication if needed

Leave unnecessary equipment behind.

Boat space disappears quickly.

Do You Need a Fishing License?

That depends on how you’re fishing.

Customers aboard properly licensed Florida saltwater charter vessels may be covered under the vessel’s licensing.

People fishing independently may need their own license unless an exemption applies.

Don’t guess.

Check Florida’s current license requirements before the trip.

Check Current Fishing Regulations

Fishing regulations can change.

A species being present in October doesn’t automatically mean you can keep it.

Rules may cover:

• Size limits
• Bag limits
• Vessel limits
• Closed seasons
• Gear restrictions
• Special management areas
• State waters
• Federal waters

Check the current Florida Fish and Wildlife Conservation Commission regulations before keeping your catch.

If you’re on a charter, your captain should also be familiar with the rules that apply where you’re fishing.
