Captain Brian's guide since 1999

How Brian actually plans trips

Fishing in Islamorada changes with the seasons. Tides, water temps, bait migrations, wind patterns and moon phases all affect what's biting. Captain Brian has been fishing these waters professionally since 1999, and this calendar reflects how he actually plans trips for his customers.

This isn't a tourist brochure. It's a practical, honest breakdown of what you can expect throughout the year, based on decades on the water.

About this guide & Islamorada

Islamorada, known as "The Sport Fishing Capital of the World", is uniquely positioned to offer access to virtually every species of fish in the hemisphere. You can fish here 365 days a year on all types of tackle.

This guide combines Captain Brian's 25+ years of on-the-water experience with local knowledge to help you plan the perfect trip for the season you're visiting. Florida consistently ranks as the #1 fishing destination in the United States, and Islamorada is its crown jewel.

December to February

Winter

Peak Reef Fishing. Excellent Consistency. Great Weather.

What's biting

  • Yellowtail Snapper
  • Mutton Snapper
  • Mangrove Snapper
  • Grouper (until January 1 closure)
  • Kingfish
  • Sailfish (conditions-dependent)
  • Mackerel in big numbers
  • Assorted reef species

Why This Season Is Good

  • Strong, predictable reef bite. Winter offers some of the most consistent action.
  • Cooler temps mean comfortable fishing conditions.
  • Great for families and beginners with steady action usually all day.

Local insight: Cold fronts can actually improve fishing. Sailfish, kingfish, and mackerel respond well to temperature drops and wind shifts.

Best trip types

  • Family Fun Charters (2–3 hrs): perfect introduction for kids.
  • 4-hour reef: perfect for consistent action.
  • 6-hour reef/offshore: mix of reef and pelagic species.
  • Full-day for mixed targets: maximize variety.

March to May

Spring

Transition Season With Big Variety & Excellent Action

What's biting

  • Yellowtail Snapper (very strong)
  • Mutton Snapper (May is prime)
  • Permit
  • Grouper opener (May 1)
  • Blackfin Tuna
  • Early mahi (conditions-dependent)
  • Tarpon (peaks April/May)
  • Blue Marlin (April-May peak)

Why This Season Is Strong

  • Increasing bait around the reefs attracts more predators.
  • Longer days, warmer water improve fishing comfort and activity.
  • High-action reef and nearshore trips with multiple target species.
  • Tarpon fishing peaks as they migrate through the Keys.

Local insight: May is one of the best months in Islamorada. The combination of mutton spawn, grouper opener, and early mahi gives multiple high-probability options.

Best trip types

  • Family Fun Charters (2–3 hrs): perfect introduction for kids.
  • Mutton-focused 6 or 8-hour: target prime mutton snapper.
  • Tarpon trip: specialized for the "Silver King".
  • Half-day reef for families: excellent variety for all skill levels.
  • Offshore full-day: for tuna and early mahi.

June to August

Summer

Calm Seas, Clear Water & Early Morning Action

What's biting

  • Mahi (peak June/July, conditions-dependent)
  • Blackfin Tuna
  • Yellowtail Snapper
  • Vermillion Snapper
  • Assorted reef species
  • Tarpon still available early summer
  • Wahoo (seasonal)

Why This Season Works

  • Typically calmer ocean conditions make for comfortable boating.
  • Early-morning reef bite is excellent before the heat of the day.
  • Great for tourists, families, and kids with predictable weather.
  • Warm water species are most active.

Local insight: Summertime mahi fishing is hit-or-miss across the Keys depending on current and weedlines. Captain Brian adjusts in real time. He doesn't waste your day "hoping" if the conditions aren't right.

Best trip types

  • Family Fun Charters (2–3 hrs): perfect introduction for kids.
  • Half-day reef/offshore: morning bite focused.
  • 6-hour mixed trips: reef and offshore combination.
  • Mahi-focused full-days (if conditions allow): target pelagics.
  • Tip: book early morning trips to beat the heat!

September to November

Fall

Light Boat Traffic, Solid Action & Perfect Conditions

What's biting

  • Yellowtail Snapper (excellent)
  • Mutton Snapper
  • Mangrove Snapper
  • Kingfish returning late fall

Why This Season Is Underrated

  • Very consistent reef bite as water temperatures stabilize.
  • Pleasant weather and milder temperatures for comfortable fishing.
  • Great for beginners and families with reliable action.

Local insight: Fall is one of the most overlooked fishing seasons. Locals know it's consistent, comfortable, and productive. It's the "secret season" for those in the know.

Best trip types

  • Family Fun Charters (2–3 hrs): perfect introduction for kids.
  • 4-hour reef: excellent value with steady action.
  • 6-hour variety trips: mix of reef and near-shore species.
