If you’re planning a fishing trip in 2025, Belize belongs at the top of your list. With its crystal-clear waters, diverse marine life, and warm tropical climate, this small country offers big rewards for anglers of all skill levels. Deep sea fishing in Belize isn’t just about casting a line—it’s about the experience of being out on the open water, the excitement of the chase, and the satisfaction of reeling in some of the most sought-after game fish in the region.

Whether you’re a seasoned sportfisher or someone looking to try offshore fishing for the first time, Belize delivers year-round opportunities—especially if you know when and where to go.

What You Can Catch While Deep Sea Fishing in Belize

The waters off Belize’s coast are rich with marine life, and deep sea fishing here is especially rewarding thanks to the country’s proximity to the drop-off beyond the barrier reef. Just a few miles offshore, the sea floor plunges dramatically, creating the perfect environment for large pelagic species.

Sailfish are one of the most exciting catches in Belize. Known for their speed and acrobatics, they’re usually spotted in deeper waters and are most abundant from April through September. Anglers often spot them darting near the surface before they strike, making for a fast-paced battle once hooked.

Blue Marlin and White Marlin are among the top prizes for serious sportfishers. These powerful fish test your strength and skill, especially during the warmer months between June and October. While marlin are elusive, they make for an unforgettable fight and a true badge of honor for anyone lucky enough to land one.

Mahi Mahi (Dorado) are not only exciting to catch with their colorful flashes and strong runs, but they’re also a favorite for those who want to take home something delicious. Their season typically peaks from May through October, though they can be found year-round depending on the water temperature.

Wahoo are incredibly fast and aggressive predators that provide one of the most exciting strikes in offshore fishing. They are often caught between November and March and are known for their razor-sharp teeth and tasty filets.

Tuna, particularly Yellowfin and Blackfin, are commonly caught offshore in Belize and can show up at different times of the year, but peak activity tends to fall between April and September. These fish put up a strong fight and are prized for their meat, especially for fresh sashimi or grilled filets.

You’ll also come across Kingfish, Bonito, Barracuda, and other strong game fish. Some are more common closer to the reef line, while others roam the deeper blue waters farther out.

Best Time of Year for Deep Sea Fishing in Belize

Belize offers excellent fishing year-round, but the best time for deep sea fishing depends on what species you’re targeting.

The dry season, which runs from late November through May, offers calm seas and excellent visibility, making it a comfortable time to head offshore. During these months, you’ll find species like Wahoo, Kingfish, and some early-season Mahi Mahi.

From June through October, the warmer waters attract larger pelagic fish such as Sailfish, Marlin, and Tuna. This is when the action heats up—both literally and figuratively. While this period overlaps with the rainy season, there are still plenty of calm, fishable days, especially in the mornings.
