How to read this forecast
Each month below highlights likely conditions across the three main regions. Central Pacific refers to Los Sueños, Jaco, and Quepos. Northern Pacific refers to Flamingo, Tamarindo, and Papagayo. Southern Pacific refers to Golfito, Puerto Jiménez, and the Osa Peninsula. Weather can shift week to week, but the patterns below are reliable year after year. If your dates are fixed, a great captain will still put you on fish by working temperature breaks, birds, and bait.
January
Central Pacific: Dry season delivers calm seas and classic billfish conditions. Sailfish numbers build, with marlin shots possible when water is purple and bait is stacked. Yellowfin tuna are present in mixed sizes. Mahi action tapers from late fall highs but remains steady offshore.
Northern Pacific: Great weather and good variety. Wahoo show around edges and ridges, making wahoo a fun bonus on trolling programs. Tuna appear along current lines. Flamingo and Papagayo are excellent for families who want fishing plus resort downtime.
Southern Pacific: One of the best windows here. Tuna schools move through consistently and roosters on the inshore side chew when tides swing. Consider a two day plan from Golfito if you want offshore variety with less traffic.
February
Central Pacific: Often peak sailfish month with multiple shots daily when conditions stack. Tuna remain dependable. Captains run balanced spreads and keep a popper rod ready for tuna that push bait with birds and spinner dolphins.
Northern Pacific: Quality weather and steady offshore fishing. Dorado numbers fade compared to December but a bright green back still shows on floating structure. Billfish encounters increase as water stabilizes.
Southern Pacific: Strong tuna and a building sailfish bite offshore. Inshore, roosterfish and snapper feed actively around river mouths and rocky points.
March
Central Pacific: Dry season stability continues. When a temperature break forms, boats slide along the seam and stack releases. Mixed tuna sizes make live bait a strong play later in the morning.
Northern Pacific: A reliable month for billfish alongside schoolie tuna. Wahoo can surprise on faster passes over structure. Calm mornings make long runs productive from Flamingo.
Southern Pacific: A very good month to combine offshore and inshore. Roosters fire on live baits near beaches with hard bottom. Offshore you can still find sailfish and tuna with the occasional marlin.
April
Central Pacific: A transition month with plenty of action. Sailfish remain strong and tuna pick up. Calm mornings favor poppers and stickbaits around bird piles.
Northern Pacific: Offshore variety with mahi still appearing on flotsam. Look for tuna on temperature edges and porpoise packs. A great month for anglers who want to try multiple techniques in one day.
Southern Pacific: Offshore remains solid. Early signs of green season life appear, which is good for bait concentration and tuna volume.
May
Central Pacific: Green season begins with cooler water and nutrient pulses. Tuna volume often jumps. Dorado rise on floating structure and lines of sargassum. Sailfish remain on the program.
Northern Pacific: One of the best months for consistent tuna numbers. Live bait and stickbaits shine when fish push sardines to the top. Wahoo encounters climb as currents intensify along contours.
Southern Pacific: Great time for tuna and mixed pelagics with fewer boats. If you want space and a shot at quality, consider a long day or an overnight plan from Golfito.
June
Central Pacific: Excellent tuna month. Look for birds and spinner dolphins and be ready to cast. Dorado remain a steady bonus. Sailfish are still present and catchable on well-run spreads.
Northern Pacific: Northern ledges load with life. Deep drop options for grouper and amberjack complement offshore tuna for anglers who want variety.
Southern Pacific: Tuna, mahi, and a good chance at billfish offshore. Inshore fishing is productive when rains stain river mouths and push bait along the beach edges.
July
Central Pacific: Strong tuna and dorado action with a summer rhythm. Afternoons can have passing squalls, but mornings are often glassy and comfortable. Families love July for school breaks and reliable fishing.
Northern Pacific: A high confidence month for tuna numbers. Add high speed passes for wahoo over ridges when the morning tide is moving.
Southern Pacific: Mixed bag offshore every day and solid inshore. If you want to introduce kids to saltwater, combine a half day inshore with a full day offshore across two days.
August
Central Pacific: Tuna remain consistent and dorado show on logs after fronts. When the sea is alive with birds and bait, topwater can be excellent.
Northern Pacific: Great for popper casting and live bait fishing on tuna. Consider two consecutive days to work different zones and capitalize on the best window.
Southern Pacific: Good to very good. A flexible approach lets the captain slide between current lines. Marlin shots appear when the water cleans up over structure.
September
Central Pacific: Late green season pattern with solid tuna volume and dependable dorado on debris. Lighter angler traffic means more room to work bird piles.
Northern Pacific: Still productive with tuna and dorado. Expect occasional weather days. A strong captain will read the radar and plan smart routes.
Southern Pacific: Often an excellent month for tuna schools and quality fish. If you want fewer boats and a chance at a big model, the south is a smart bet.
October
Central Pacific: Tuna keep chewing. Dorado can be very good as debris fields tighten in prevailing currents. Sailfish return to the headline as water stabilizes toward late month.
Northern Pacific: Productive with dorado and tuna. If you like color and variety, this is a fun time to fish Flamingo and Papagayo.
Southern Pacific: Late season quality with fewer boats. A great time to plan a two day push for tuna and billfish if your dates allow.
November
Central Pacific: Transition toward dry season comfort. Dorado can be excellent and tuna remain steady. Early season sails start to show. A perfect month for anglers who want calm mornings and mixed offshore action.
Northern Pacific: Strong dorado and steady tuna. Logs and weedlines can deliver fast bites. High speed passes for wahoo are worth trying at first light.
Southern Pacific: Offshore variety stays good with a gradual move toward summer stability. Inshore roosters respond well to live baits near drains and rocky points.
December
Central Pacific: A favorite for holiday travelers. Dorado and tuna stay in the picture and sails build into January. Calm seas and short runs equal maximum time with lines in the water.
Northern Pacific: Dorado headline with schoolie tuna stacked on current lines. Mix in billfish as water clears. A great way to end the year with family.
Southern Pacific: Consistent offshore with a rising sailfish trend. If you want space and scenery, the south delivers both with quality action.
Trip formats to match the forecast
Full day offshore: The standard for tuna, dorado, sails, and marlin. Most boats run 20 to 40 miles, then shift between trolling, live baiting, and casting poppers depending on what the crew sees. Read more here: Offshore Fishing in Costa Rica.
Inshore days: Perfect add on for families and for anglers who want roosters, snapper, and jacks close to the beach. If you are splitting a week between offshore and inshore, compare options here: Inshore vs Offshore Fishing in Costa Rica.
Overnight and FAD expeditions: For serious anglers who want to maximize shots at marlin with bonus tuna at dawn and dusk. These trips leave in the afternoon, arrive at first light on the seamounts, and keep you in the game across multiple tide cycles.

Species highlights for 2026
Sailfish: Central Pacific peaks from December into March with consistent shots the rest of the year. Quepos and Los Sueños are prime bases for dedicated release counts. See the species page: Sailfish.
Marlin: Blue and striped marlin appear year round with strongest opportunities around seamounts and long range grounds. Black marlin show when bait is thick on structure. Learn more here: Marlin Sport Fishing.
Yellowfin tuna: A staple every month with volume spikes from April through November. Casting poppers into porpoise schools is a bucket list bite. Details here: Yellowfin Tuna.
Dorado: Best from late October through January when flotsam and weedlines concentrate. A holiday favorite. See the overview: Dorado.
Wahoo: Edge and ridge specialist with encounters through the dry season and green season pulses in the north. Fast passes and tight spreads help. Read more: Wahoo.
Roosterfish and snapper: Inshore action is dependable year round with best bites around tide swings and light current. Good captains can make inshore sing even on breezy offshore days. Learn more about Roosterfish and Snapper.
Planning tips for 2026
- Book two to three days minimum: This gives you a cushion for weather and lets the captain adapt based on what they find the first day.
- Set a goal before you board: Tell the crew if you prefer numbers for the cooler, trophy hunting, or topwater casting. Clear goals help the captain choose zones and tactics.
- Travel smart: Stay near your marina to shorten mornings and be first to the grounds. Los Sueños and Jaco offer the widest lodging range. Flamingo and Papagayo pair fishing with resort comfort. Golfito and the Osa deliver adventure with fewer boats.
- Licenses and responsible harvest: Be sure everyone in your group is covered. A quick read here keeps you compliant and sustainable: Costa Rica Fishing Licenses.
- Consider an overnight: If a milestone fish is the goal, the extra tide cycles offshore are a real advantage. Compare options on Overnight Fishing in Costa Rica.
