Los Sueños & Jaco Fishing Report: October 15, 2025 - What's Biting?

The vibrant green season in Los Sueños and Jaco is reaching its peak, making mid-October one of the most exciting times of the year to book your sportfishing adventure. The waters are alive, the scenery is breathtaking, and the fishing is hot. It's the perfect time to create unforgettable memories aboard one of our premier fishing charters.

Mid-October 2025 Fishing Conditions in Los Sueños & Jaco

As we move through October, you can expect classic "green season" weather here on the Central Pacific coast. Air temperatures are comfortable, typically ranging from the mid-70s to low-80s ∘ F (24 ∘ C to 29 ∘ C). While October is one of our rainiest months, the pattern is predictable: beautiful, calm mornings perfect for fishing, followed by afternoon showers that cool things down and keep the rainforest lush.

The consistent cloud cover is an angler's best friend. It keeps the water temperature stable and encourages predatory fish to be more active throughout the day. With typical wind speeds remaining low around 6 MPH, the seas are generally calm, making for a smooth and enjoyable day offshore. The rain runoff from the mountains also pushes nutrient-rich water into the ocean, igniting the entire food chain and leading to incredible feeding frenzies.

What's Biting in Costa Rica this October?

The nutrient-rich runoff from the green season rains supercharges the inshore and offshore ecosystems. This means incredible action for anglers! Here’s a look at what our charters are targeting this October:

Red Snapper

October is a prime month for Snapper. These hard-fighting and delicious fish are a favorite target on inshore trips. While many are caught near rocky structures, if you're hunting for a true trophy Cubera Snapper, which can exceed 100 pounds, a deeper reef excursion is your best bet.

Blue Marlin

While the peak Marlin season is just around the corner, October still delivers thrilling offshore battles. Schools of baitfish, particularly tuna, are abundant, and where there are tuna, the Blue Marlin are never far behind. Hooking into one of these giants, which can weigh over 1,000 pounds, is the dream of every angler visiting our waters.

Yellowfin Tuna

Thanks to Costa Rica's strong tuna conservation laws that protect our waters, the Yellowfin Tuna fishing is world-class. It's common to find massive schools of "porpoise-chasing" tuna, with individual fish weighing well over 100 pounds. Landing a powerful Yellowfin is a perfect way to cap off an incredible day of fishing.

Roosterfish

The legendary Roosterfish continues to be a star attraction for inshore anglers in October. Famous for their incredible fight and unique dorsal fin, these powerful predators patrol the beaches, river mouths, and rocky outcrops of the Jaco coast. October remains a fantastic month to land a trophy Roosterfish.

You can also expect fantastic action with Sailfish, Mahi-Mahi (Dorado), Amberjack, and Jack Crevalle, making for a diverse and exciting day on the water.
