Jaco Fishing in June and July: A Prime Season for Mahi Mahi and Tuna

Jaco, Costa Rica, is renowned for its world-class sport fishing, drawing anglers from around the globe to its rich Pacific waters. As we move into the heart of the rainy season, the fishing conditions in Jaco become even more thrilling, especially for those targeting mahi mahi and tuna. Here’s what you need to know about fishing in Jaco during June and early July.

The Rainy Season: What to Expect

In Jaco, the rainy season typically spans from May to November, with the heaviest rains occurring in September and October. However, June and the beginning of July present a unique window of opportunity for fishing enthusiasts. Here’s why:

  • Afternoon Showers: While rain is common in the afternoons, mornings often remain clear and calm, providing ideal conditions for fishing.
  • Cooling Effect: The rain helps cool the ocean surface, creating an environment that attracts a variety of fish species closer to the shore.
  • Spectacular Sunrises: Early risers are rewarded with stunning sunrises over the Pacific, making the early start well worth it.

Prime Time for Mahi Mahi and Tuna

The rainy season, particularly in late June and early July, is known for its exceptional fishing for mahi mahi (dorado) and tuna. Here’s why this period is so special:

Mahi Mahi

Mahi mahi, with their vibrant colors and acrobatic fights, are a favorite among anglers. During this time, the population of mahi mahi increases significantly. They are often found near floating debris or sargassum patches, which are more prevalent after heavy rains. These conditions make for:

  • Consistent Bites: Anglers can expect steady action with numerous bites throughout the morning.
  • Large Specimens: The cooling waters and abundant food supply attract larger mahi mahi, offering the chance to catch trophy-sized fish.
  • Exciting Fights: Known for their high jumps and strong runs, mahi mahi provide an exhilarating experience for both novice and experienced anglers.


Tuna fishing in Jaco also reaches its peak during late June and early July. Yellowfin tuna, in particular, are abundant during this season. The rainy conditions help create:

  • Favorable Conditions: Cooler surface temperatures and increased baitfish attract schools of tuna closer to the surface.
  • Heavy Action: Anglers can enjoy fast-paced fishing with multiple hook-ups in a single outing.
  • Quality and Quantity: Expect to catch sizable yellowfin tuna, often in the 20 to 80-pound range, with the possibility of even larger catches.

Recent Fishing Reports

As we approached the end of June, anglers in Jaco experienced a slight increase in rainfall. Despite the wet conditions, the fishing remained outstanding. Mornings were particularly productive, with numerous reports of successful trips and impressive catches of both mahi mahi and tuna.

  • Late June: Anglers reported a bit more rain, but the fishing remained stellar. The mahi mahi were plentiful, and the yellowfin tuna were biting aggressively.
  • Early July Outlook: The beginning of July is expected to bring a brief respite from the heavier rains, making it an excellent time to plan a fishing trip. The slight decrease in rainfall should further improve the already favorable fishing conditions.

  • Start Early: Head out at dawn to take advantage of the calm morning waters and avoid the afternoon showers.
