Best Time of Year for Fishing in Quepos Costa Rica: A Seasonal Guide

Planning a fishing trip to Costa Rica and wondering when to visit Quepos? Choosing the right time of year can make a big difference in the type of fishing experience you have.

Quepos is one of Costa Rica’s best-known sport-fishing destinations, with access to both productive offshore waters and excellent inshore fishing grounds. Anglers come here looking for sailfish, marlin, mahi-mahi, tuna, roosterfish, snapper, and other Pacific species.

But there is no single month that guarantees the perfect fishing trip.

Different species follow different seasonal patterns, while weather, ocean conditions, bait availability, water temperature, and daily conditions can all influence what happens on the water. Costa Rica’s official tourism information identifies sport fishing in Quepos as a major dry-season activity, particularly for sailfish, marlin, and roosterfish.

If you are researching Quepos fishing charters, understanding the seasons can help you choose a travel period that matches the type of fishing you want to experience.

When Is the Best Time to Fish in Quepos?

For many anglers, December through April is an especially popular period for fishing in Quepos.

This corresponds broadly with Costa Rica’s dry season on the Central Pacific coast. The country’s tourism board identifies December through April as the dry-season period for the Central Pacific and specifically highlights sport fishing in Quepos during this season.

This period is particularly associated with offshore fishing for sailfish and other billfish.

However, fishing does not simply stop when the dry season ends.

The Central Pacific has fishing opportunities throughout much of the year, and different species can become more interesting during different months. For example, official Costa Rica tourism information lists tuna as a year-round species, while identifying June through September as a stronger period. Mahi-mahi are also listed as available year-round, with May identified as a peak period in the tourism board’s regional fishing information.

That means the “best” time depends on your target species.

December Through April: Prime Dry-Season Fishing

December through April is one of the most popular periods for offshore fishing Quepos Costa Rica.

The weather is generally drier than during the green season, and this is an important period for billfish. Costa Rica’s tourism board specifically lists sailfish, marlin, and roosterfish among the major sport-fishing opportunities in Quepos during the dry season.

Sailfish

Sailfish are one of the main reasons anglers travel to the Central Pacific.

FECOP identifies January through April as the peak sailfish period from the Gulf of Nicoya southward. Its fishing information also describes the Central and South Pacific as particularly productive for billfish from roughly November through April.

For anglers specifically interested in sailfish, January, February, March, and April can therefore be attractive months to consider.

That does not mean sailfish cannot be encountered outside those months. It simply means seasonal patterns tend to make this part of the year particularly important for anglers targeting them.

Marlin

Marlin can also be targeted offshore around Quepos.

The Costa Rica tourism board’s regional fishing information lists September through November as a marlin season, while other fishing sources describe marlin as available during broader periods of the year.

This illustrates why it is useful to look beyond a simple “best month” answer.

If marlin is your primary target, talk with your charter captain about recent local conditions rather than relying only on a general annual calendar.

May: A Transition Month

May marks an important seasonal change in the Central Pacific.

Costa Rica’s Pacific dry season transitions into the wetter green season around this time. The official climate guide identifies April as a transition month, with rains beginning around early May in the Central Pacific.

For anglers, this does not necessarily mean fishing suddenly becomes unavailable.

Instead, weather becomes an increasingly important factor when planning offshore trips.

May can also be an interesting period for mahi-mahi. Costa Rica’s official fishing information lists mahi-mahi as available throughout the year and identifies May as a peak period in the Central Pacific fishing calendar.

This makes May worth considering for travelers who are interested in more than just billfish.

June Through September: Green Season Fishing

The green season runs through much of the middle and later part of the year.

Rainfall generally increases, but fishing opportunities continue.

This is particularly important for travelers who assume that visiting Quepos outside the dry season means they cannot fish.

That is not the case.

Costa Rica’s tourism information lists tuna as a year-round species and identifies June through September as a stronger period for tuna. It also lists roosterfish from June through September in its Central Pacific fishing calendar.

Yellowfin Tuna

Yellowfin tuna are an important offshore target and can provide a completely different type of fishing experience from billfish.

Tuna are listed as available year-round in Costa Rica, with June through September identified as a stronger seasonal period in the Central Pacific information published by the tourism board.

If tuna is high on your fishing wish list, the green season should not automatically be ruled out.

Roosterfish

Roosterfish are another popular target for anglers fishing closer to shore.

FECOP notes that roosterfish are available year-round along Costa Rica’s Pacific coast, while the official regional calendar identifies June through September as a seasonal period for roosterfish in the Central Pacific.

This makes the middle of the year particularly interesting for anglers considering inshore fishing Quepos Costa Rica.

October and November: Another Seasonal Shift

October and November bring another change in weather and fishing conditions.

The Pacific rainy season generally becomes wetter toward September and October, while November is considered a transition month.

That can affect offshore trip planning, especially when weather conditions influence how far boats can comfortably travel.

However, these months should not simply be considered “bad fishing months.”

FECOP describes the Central and South Pacific as productive fishing regions from November through April, with billfish among the major offshore targets.

November can therefore be an interesting transition period for anglers interested in offshore fishing.

 

Quepos Fishing by Month

Here is a simple way to think about the annual fishing calendar.

January

January is part of the dry season and falls within the stronger sailfish period identified by fishing organizations.

This can be an attractive month for anglers interested in offshore billfish.

February

February continues the dry season and sailfish period.

Quepos also hosts the Quepos Billfish Cup, highlighting the importance of sport fishing in the area during this part of the year.

March

March is typically part of the dry season in the Central Pacific and remains within the recognized sailfish period.

It is also one of the warmer, drier months in the region.

April

April is another important month for sailfish, although it also marks the transition toward the wetter part of the year.

FECOP identifies January through April as the peak sailfish period in the Central Pacific and southern Pacific regions.

May

May marks the beginning of the green season.

It can be an interesting month for mahi-mahi, which the Costa Rica tourism board identifies as a year-round species with a May peak in its regional fishing calendar.

June

June brings wetter conditions but can be attractive for anglers interested in tuna and roosterfish.

July

July falls within the green season and can offer opportunities for tuna and inshore species.

The Central Pacific also experiences a relative decrease in rainfall around July and August compared with the wettest periods, sometimes referred to as the “veranillo” or little summer.

August

August continues the green season and can provide opportunities for tuna, roosterfish, and other inshore and offshore species.

Weather remains an important consideration when scheduling a trip.

September

September is among the wetter months on the Pacific coast, but it is also listed as part of the seasonal period for roosterfish and tuna in the Central Pacific fishing calendar.

October

October can be one of the wetter months, so flexibility is useful when planning an offshore charter.

Mahi-mahi and other offshore species can still be encountered, depending on local conditions.

November

November is a transition month between the wetter season and the drier period.

It can be an interesting month for anglers interested in the return of stronger offshore billfish activity.

December

December begins the dry season and marks the start of a particularly popular period for sport fishing in Quepos.

Sailfish activity becomes increasingly important as the season progresses toward January through April.

Offshore Fishing vs. Inshore Fishing in Quepos

One of the most important decisions when booking a fishing trip is whether you want to focus on offshore or inshore fishing.

These experiences are quite different.

Offshore Fishing

Offshore fishing Quepos Costa Rica takes anglers farther from the coastline into deeper Pacific waters.

Common targets can include:

• Sailfish
• Marlin
• Mahi-mahi
• Yellowfin tuna
• Wahoo

Offshore trips often require more time because the boat needs to travel to the fishing grounds.

The dry season is particularly popular for offshore sport fishing in Quepos, especially for billfish.

Inshore Fishing

Inshore fishing Quepos Costa Rica generally takes place closer to the coast.

Potential targets include:

• Roosterfish
• Snapper
• Jack crevalle
• Snook
• Grouper
• Other coastal species

FECOP describes roosterfish as a year-round Pacific inshore species, along with a variety of snapper, grouper, jacks, and other fish.

Inshore fishing can therefore be an option when travelers want a shorter fishing experience or prefer targeting coastal species.

Is the Rainy Season Bad for Fishing?

Not necessarily.

This is one of the biggest misconceptions about fishing in Costa Rica.

The green season brings more rain, but fish do not simply disappear.

Instead, weather becomes a larger factor in planning your trip.

Rainfall can affect:

• Ocean conditions
• Boat travel
• Visibility
• Wind
• Waves
• River runoff
• Daily fishing locations

A charter captain can adjust the day’s plan based on actual conditions.

This is one reason booking with an experienced local captain is important.

Why Fishing Conditions Matter More Than a Calendar

A seasonal fishing calendar is useful, but it should not be treated as a guarantee.

Fish are wild animals.

Their location and behavior can change based on:

• Water temperature
• Currents
• Baitfish
• Ocean conditions
• Weather
• Seasonal migrations
• Fishing pressure
• Local conditions

Even during a recognized peak season, one day can be very different from the next.

Likewise, a month considered outside the traditional peak period can still produce memorable fishing.

For that reason, ask your captain what species have been active recently, rather than relying only on an annual fishing chart.

When Should You Book Quepos Fishing Charters?

If your primary goal is sailfish, the January-through-April period is particularly worth considering.

If you are more interested in tuna or roosterfish, the middle months of the year can also be attractive.

If mahi-mahi is your target, consider the seasonal information for this species while remembering that mahi-mahi can be encountered throughout the year.

If you have flexibility, another useful strategy is to choose your travel dates based on the species you most want to target rather than simply looking for the driest weather.

What About Manuel Antonio Fishing Charters?

Many visitors staying in Manuel Antonio search for Manuel Antonio fishing charters because Quepos and Manuel Antonio are so close to each other.

In practical terms, Quepos is an important fishing departure point for visitors staying in the wider Manuel Antonio area.

Costa Rica’s official tourism information identifies Quepos and Marina Pez Vela as important fishing centers in the Central Pacific.

Therefore, when researching Manuel Antonio fishing, it is useful to search for both Manuel Antonio and Quepos charter options.

The important thing is to confirm the exact meeting point and transportation arrangements when booking.

What Is the Best Month for Quepos Fishing?

There is no universal answer.

If your priority is sailfish, January through April is a particularly important period based on established seasonal patterns for the Central Pacific.

For tuna and roosterfish, June through September can be interesting based on the Central Pacific seasonal fishing calendar.

Mahi-mahi can be encountered year-round, with May identified as a peak period in the regional tourism calendar.

Marlin has a more variable seasonal pattern, and sources identify different periods of increased activity. This is another reason to discuss current conditions with your captain before selecting a trip date.

Tips for Planning Your Quepos Fishing Trip

Before booking, consider these questions:

What fish do I want to catch?

Your target species should influence your travel dates.

Do I want offshore or inshore fishing?

These are different experiences with different target species.

How long do I want to spend on the boat?

A longer trip generally gives the captain more time to reach offshore fishing grounds.

Am I flexible with dates?

Flexibility can be useful, especially during the rainy season.

What are local captains seeing right now?

Recent reports can be more useful than a generic annual calendar.

What does the charter include?

Ask about rods, reels, bait, tackle, drinks, meals, transportation, and other inclusions before booking.
