What to Expect: Fishing Conditions in September 2025

September marks a fantastic period for fishing in the Los Sueños area. While it's considered the green season, the rainfall brings immense benefits, cooling the waters and stirring up baitfish, which in turn attracts a rich diversity of predatory game fish.

• Weather: Expect warm, humid conditions with temperatures typically ranging from 75°F to 83°F (24°C to 28°C). Mornings are often clear and sunny, with rain showers more common in the afternoons.
• Daylight: You'll have ample time on the water with approximately 12 hours of daylight. The sun rises around 5:30 AM and sets just after 5:30 PM, maximizing your fishing opportunities.
• Water Conditions: The nutrient-rich runoff from the rainforests creates a feeding frenzy, drawing fish closer to shore and making for an action-packed day.

Our charter fleet at Adventure Tours Costa Rica is equipped with top-of-the-line gear and safety equipment, ensuring you can focus on the thrill of the catch in complete comfort, rain or shine.

Target Species: What's Biting in Los Sueños?

The unique conditions of September bring a variety of prized species within reach. Our captains have decades of local experience and know exactly where to find the fish you're looking for.

Inshore Fishing Forecast

The inshore fishing this time of year is exceptional. The rocky outcrops, reefs, and river mouths near Los Sueños become hotspots for aggressive feeders.

Roosterfish (Pez Gallo)

September is a peak month for targeting the iconic Roosterfish. Known for their incredible strength and distinctive dorsal fin, these bucket-list catches are a favorite among light-tackle enthusiasts. They aggressively strike live baits like lookdowns and blue runners. Landing a Roosterfish provides not only a spectacular fight but also an incredible photo opportunity.

Cubera Snapper

Another inshore giant is the Cubera Snapper. These powerful fish are known for their cunning and brute force, often requiring heavy tackle to pull them from their rocky homes. While they can be found inshore, larger specimens patrol the deeper reefs. A fresh Cubera Snapper also makes for an excellent dinner, which the crew can prepare for you.

Offshore Fishing Outlook

Venture offshore from Los Sueños Marina, and you'll enter the realm of true bluewater giants. The FADs (Fish Aggregating Devices) and natural underwater structures are magnets for pelagic species.

Mahi-Mahi (Dorado)

The green season is famous for its Mahi-Mahi run. These brilliantly colored fish are acrobatic fighters and travel in schools, meaning once you find one, you can often land several. They are voracious eaters and will attack a wide variety of trolled baits and lures. Our crews are experts at locating the weed lines and debris that these fish love to congregate around.

Wahoo

Get ready for a reel-screaming run if a Wahoo strikes. As one of the fastest fish in the ocean, their explosive speed is legendary. September sees a healthy number of Wahoo around floating debris and underwater pinnacles. A wire leader is essential, as their razor-sharp teeth can slice through standard monofilament lines in an instant.

The Tuna Law: A Game-Changer for Sportfishing

The groundbreaking "Tuna Law," which prohibits commercial purse seine boats from operating within 80 miles of Costa Rica's coastline, continues to have a profoundly positive impact on our marine ecosystem. This conservation-focused legislation has revitalized our fisheries.

For you, the angler, this means:

• More Billfish: Marlin and Sailfish populations have rebounded, as they are no longer caught as bycatch by commercial vessels.
• Healthier Oceans: The law protects dolphins, turtles, and other marine life, ensuring a more vibrant and sustainable fishing environment for future generations.
• Abundant Tuna: Yellowfin Tuna are now found closer to shore in massive schools, offering incredible action. Tourist charters can now bring up to 15 tuna to port, providing plenty of fresh sashimi for your group after a successful day.
