Costa Rica Deep Sea Fishing: we have billfish around the year but the peak months are from January to April. It is possible to catch species like Blue Marlin, Black Marlin, and Pacific Sailfish but also is possible to catch Mahi Mahi, Wahoo and sometimes large Yellowfin tuna schools are around, with 40 to 100 pounds tunas.
Keep in mind that Costa Rica passed regulations that make it illegal to remove the billfish from the water for the purpose of taking a picture.
That fishing is done 25 miles away from the shore
Do not forget to bring sunglasses, hat, comfortable clothes, sun block and a raincoat for the months of May to November.
We recommend you to bring a dry bag to store your cell phone, cameras and other things that can be damaged by water. And if you plan to keep some fish, do not forget to bring a cooler and plastic bags to pack the fish fille that you are going to take with you.
