Islamorada, Florida is known worldwide as the Sportfishing Capital of the World—and for good reason. Located in the heart of the Florida Keys, it offers fast access to deep water, the Gulf Stream, and year-round excellent offshore fishing opportunities. If you’re planning a trip and want to know the best time of year to fish offshore in Islamorada, this guide is for you.
At LegaSea Charters, we run offshore fishing trips all year long and have extensive experience to know when certain species peak. Here’s what you can expect throughout the year and when to plan your trip based on the species you want to target.
Year-Round Offshore Fishing in Islamorada
One of the best things about fishing in Islamorada is that there’s always great fishing going on offshore. Depending on the time of year, you’ll have opportunities to target pelagic species like mahi-mahi, tuna, sailfish, wahoo, and even swordfish.
There is no singular answer for the best time of year, that depends on your goals for the charter! The fishing is fantastic year round, but seasons do bring change throughout the year.
Here’s a month-by-month breakdown to help you choose the best time for your fishing goals.
Winter (December – February)
Top Catches:
- Sailfish
- Blackfin Tuna
- King Mackerel
- Wahoo (especially near the full moon)
Why Go: Winter is peak sailfish season, especially when cold fronts push through. If you’re into light-tackle action and watching sailfish tailing down the waves, this is your time. Expect clear skies, cooler temps, and strong bites on the edge of the reef.
Spring (March – May)
Top Catches:
- Mahi-Mahi (Dolphin Fish)
- Blackfin Tuna
- Wahoo
- Amberjack
- Permit (near offshore wrecks)
Why Go: Spring kicks off mahi-mahi season, with fish starting to show up under weed lines and floating debris offshore. This is also a great time to mix in wreck fishing for amberjack and tuna schools along the reef line.
Summer (June – August)
Top Catches:
- Mahi-Mahi (peak season)
- Wahoo
- Blackfin Tuna (early mornings or late afternoons)
- Swordfish
- Tilefish, Snowy Grouper (deep drop trips)
Why Go: Summer is prime time for grouper fishing and for mahi-mahi, especially in July and August. The seas are typically calmer, making it a great time for families or less experienced anglers. Deep drop fishing and daytime swordfishing are also productive in summer’s flat calm conditions.
Fall (September – November)
Top Catches:
- Wahoo
- Sailfish (late fall)
- Blackfin Tuna
- Mahi-Mahi (smaller fish)
- Grouper & Snapper near wrecks
Why Go: Fall is often overlooked, but it’s a fantastic season for anglers in the know. Fishing pressure is often the lightest all year, and the action can be lights out. Wahoo become more active, especially around moon phases, and sailfish start to show up by late October. It’s also a great time to target blackfin tuna and bottom species with fewer boats on the water.
When’s the Best Time Overall?
- For variety and action: Spring and Summer
- For trophy pelagics like sailfish or wahoo: Winter and Fall
- For mahi-mahi or grouper: May through August
- For calm seas and family-friendly trips: Summer
- For less-crowded waters and great conditions: Fall
Ultimately, the best time to fish offshore in Islamorada depends on your goals and group. If you’re not sure, our captains are always happy to recommend the right season and trip for what you’re looking to catch.
