Although Costa Rica is worldwide famous for its rich and diverse inshore and offshore big game fishing experience, most people excited about fishing in Costa Rica for the first time think mainly about catching marlins and sailfish, which is understandable being in the world’s capital of billfish, but here we show you many other fishing species (and their seasonal fishing calendar) you will also enjoy a lot catching when being here.

What is the best time of year to fish in Costa Rica?

Without a doubt, one of the most frequently asked questions for anglers visiting Costa Rica for the first time is when is the best time or season for fishing in Costa Rica.

In short, most fishermen and fishing charter captains will simply say that the best season to fish in Costa Rica goes from December to April, and so we agree (for most pelagic species) but, this quick answer does not mean you won’t have a great fishing experience any other month of the year, at all.

The Pacific Ocean waters of Costa Rica’s West Coast (Los Suenos – Jaco Beach region) is excellent year-round for deep sea and inshore fishing, however, during certain months of the year, different species of Game fish are more abundant than others.

To see what months typically represent the best time to fish for the different species we catch in Costa Rica please review the yearly fishing season calendar, below.

Sailfish (Pez Vela)

Sailfish facts:

These are the easiest of all the billfish to identify. Their tall, arching dorsal fin is filled with blood vessels and is used to regulate the fish’s body temperature. Its back and dorsal fin are dark blue, sides are silver, and belly is white. The bill is usually twice the length of the fish’s lower jaw.

Where found:

Sailfish will migrate in deep, warm waters, but they’re known to move near shore for feeding. Typically caught out of Los Suenos area anywhere from 18-35 miles off shore.

Feeding Habits:

Sailfish eat squid, octopus, mackerel, mullet, flying fish, needlefish, and other small fish. Although they travel in deep water, they will usually feed in mid-depths as well as close top the surface.

Peak Season:

While trophy Sail Fish are caught in strong numbers out of the Los Suenos region year-round, January through the end of June have historically proven to be the best time frame to catch large quantities of these fish in this region.

Sporting Qualities:

Sailfish are incredible sprinters, reaching speeds of up to 65mph. When hooked, they are known to make spectacular long hard runs and aerial leaps. They tend to travel in packs ranging from 3 to 30, making chances for a double hook-up very good.

Most Effective Angling Technique:

Sails are prime targets for medium-tackle bait-and-switch. Once incited, they will pursue a baitfish longer and more aggressively. This gives anglers a good chance of luring a sailfish from a teaser to a hooked drop back bait and affords maultiple hookups at the same time.

Food Quality:

None: All Sailfish caught aboard our fishing boats are live-released at the leader once brought boatside.

Preferred Water Temps:

70 to 86 °F

Blue Marlin (Aguja Azul)

Blue Marlin Facts:

The Atlantic and Pacific Blue marlin look nearly the same in their appearance. The upper and rear portions of the body are dark, brilliant blue in color, and that includes the dorsal fin. The lower portion has a silver white color. In many cases, there are up to 15 vertical stripes, consisting of small dots and narrow bars, also in a brilliant blue color.

Where found:

Blue marlin can be found in tropical and warm temperate waters around the globe, mostly in the Pacific, Atlantic and Indian Oceans. It is the most tropical of the billfish and is often found in waters near the equator. In eastern Pacific waters, they can be found in an area generally from southern California along the coast of Mexico through Costa Rico and as far down as Peru in South America.

Feeding Habits:

Blue marlin feed primarily near the surface, though they occasionally dive to deeper water to feed, depending on where their prey is found. Their diet consists mostly of fish and other sea life found near the surface and is highly dependent upon location. This diet can include tuna, mackerel, squid, octopus and any number of fish species indigenous to the environment.

Peak Season:

While caught year round here, November & December offer the largest migration of all Marlin Species that travel through the Los Suenos region. During these months, impressive numbers of Blue, Black, and Striped Marlin are caught daily on our fishing charter boats.

Sporting Qualities:

Most believe Blue Marlin are the most sought after of all the ocean sport fish. A super strong and powerful bill-fish, blue marlin will fight hard and run fast for many hours on end, especially when you are hooked up to a very large marlin. They can suddenly dive to deep water and can make wild jumps like some type of fish acrobatic. With impressive endurance, it is not uncommon to see a hooked fish make up to 15 or more spectacular jumps. This fish can be a true test of an anglers deep sea fishing skills.

Most Effective Angling Technique:

Anglers commonly troll brightly colored lures and teasers as well as natural baits such as mackerel, tuna, bonito and ballyhoo in hopes of enticing one of these giants. Blue marlin anglers will look for temperature breaks in the water and follow large concentrations of baitfish.

Food Quality:

None: All Marlin caught aboard our fishing charter boats are live-released at the leader once brought boatside.

Preferred Water Temps:

70 to 86 °F
