August Fishing Delivers the Heat Inshore..Tuna Chaos Offshore

August Fishing Report – Crocodile Bay, Costa Rica

August brought another incredible month of fishing here on the Osa Peninsula, reminding us exactly why this place is considered one of the last true frontiers for anglers. With fairly calm seas most mornings and heavier weather holding off until the afternoons, conditions were ideal for both inshore and offshore adventures.

 

inshore

 

The Osa Peninsula is more than just a fishing destination—it’s pure paradise. Towering rainforest-covered mountains meet a rugged, untouched coastline, and the surrounding waters are teeming with life. Every trip offshore feels like a nature tour, with frequent sightings of dolphins, sea turtles, manta rays, and, during this time of year, migrating humpback whales putting on a show. It’s a visual spectacle that leaves even seasoned travelers amazed.

Inshore Fishing – Roosters on Fire

 

The inshore bite stole the show this month. It’s been a long time since we’ve seen action this consistent and explosive. Boats were landing 15 to 30 roosterfish per day, and these weren’t just small fish—many were fully grown giants in the 45–70 lb range.

These fish are absolute brutes, known for their power and endurance, and they’re also the ultimate photo op. They put up a serious fight and make every angler earn that picture-perfect moment.

In addition to roosters, the Cubera snapper were chewing hard, providing more back-breaking battles near the reefs and rocky outcroppings. Throw in jack crevalle, bluefin trevally, and the occasional African pompano, and it was non-stop action close to shore.

 

Offshore Fishing – Tuna Takeover

 

 

 

While the billfish were a bit scattered this month, the offshore bite was dominated by monster yellowfin tuna. We’re talking big schools and even bigger fish—many in the 60–100 lb range, with some pushing well beyond that.

Birds, spinner dolphins, and boiling water made it easy to find the action. And once you’re hooked up, you’d better be ready—they don’t give up easily. It’s always exciting when the offshore grounds light up with that kind of tuna action. Our anglers took full advantage, bringing in coolers full of fresh sashimi-grade fillets and memories of long, hard fights.

 

 

 

 

Looking Ahead – Billfish Season Approaching

 

As we roll into September and October, we’re expecting billfish numbers to rise again. These months often bring excellent opportunities for sailfish and marlin, especially as the rains stir up the currents and baitfish push through.

It’s a great time to plan an offshore run—just pack your gear, embrace the adventure, and get ready for some big game action.

 

So, if you’re thinking about your next fishing trip, there’s no better place to be than the Osa Peninsula—home of Crocodile Bay.

 

See you in paradise,
