High winds can ruin the deep sea fun in northern Guanacaste, while the south enjoys peak Billfish season. Wherever you are, you can find giant Snook and Roosterfish in the shallows.

If you can’t face the bad weather and bitter cold February brings, head to Guanacaste for 90-degree heat without a cloud in sight. You’ll also find big Snook and Roosterfish, as well as Marlin in the south.

The Snook bite drops off in March, but Roosterfish are still demolishing baits and denting lures in the shallows. Offshore, the southern Blue Marlin season goes out with a bang.

The wind dies down in the north and you can finally get offshore in search of Marlin, Sailfish, Wahoo, Mahi Mahi, and Tuna. Inshore, things are quietening down, but you can still find big Jacks.

Billfish season really gets going in the north, with Black Marlin and Sailfish in huge numbers. The rains also pick up in May and getting offshore can be a good way to beat the humidity.

June is one of the wettest months of the year in Guanacaste but that won’t put out the fire on the Marlin trips in the north. All the rain washes a ton of FADs into the sea, which makes it perfect for Mahi fishing.

Locals celebrate Guanacaste’s annexation to Costa Rica with parades and shows. Blue Marlin peak in the north, joining Blacks, Stripes, and Sails for some of the best Billfishing you’ll see all year.

FADs and reefs continue to produce huge, tasty fish throughout September. You can find big game pelagics just a stone’s throw from shore this time of year if you don’t mind getting wet.

The rain shows no sign of stopping in October and high humidity can sap your strength. Wade fishing for Snook can be a great way to keep cool. Well, you’re going to get wet either way!

Winds pick up in the north, but so do the Snook and Roosterfish. In the south, Blue Marlin start their winter season as Yellowfin Tuna calm down and the reef fishing begins to drop off.

Monster Snook and Roosterfish make for endless fun inshore in December. Down south, Blue Marlin fight hard while the reefs serve up a festive feast all along the coastline.
