When to fish in Seychelles

YFS (Yachting Fishing Specialist) shares our in-depth expert guide to the best fishing seasons in the Seychelles. In these waters, timing is everything: wind patterns, rainfall, sea surface temperature, and bait migrations all dictate predator behaviour. Spread across 115 idyllic islands and an enormous Exclusive Economic Zone, the Seychelles offer year-round tropical conditions, but with marked seasonal variations that separate good trips from extraordinary ones. With our guidance, you’ll know exactly when to come, which techniques to prioritise, and which species peak at specific times — whether your passion is popping, jigging, trolling, or live bait fishing.

Seychelles: climate, winds & monsoons — how seasons affect fishing


The Seychelles archipelago lies just south of the equator in the heart of the southwest Indian Ocean. Protected from cyclones by its equatorial position, it benefits from stable tropical temperatures averaging 26–29 °C (79–84 °F) throughout the year. Unlike temperate destinations, the fishing seasons here are not about hot vs. cold, but about wind direction, sea state, and bait availability. The two monsoon patterns dictate everything:


  • October to May (prime fishing window): This is the heart of the Seychelles fishing season. The winds ease, seas flatten, and water clarity improves dramatically. Predator fish move actively across the plateau, chasing dense schools of baitfish. Short tropical showers are common, but they actually help moderate sea surface temperatures and can often trigger aggressive feeding sprees. It is in this window that record-class giant trevally, dogtooth tuna, marlin and sailfish are at their most accessible.
  • June to September (SE trade winds): A completely different picture: the south-east trades blow strongly, seas grow rough, and long passages become uncomfortable. Fishing pressure decreases dramatically as few boats operate. YFS prioritises safety and comfort, so we do not operate charters in this period. For those planning their dream trip, it is essential to avoid these months if fishing is your main goal.

Rainfall distribution is uneven. Northern granitic islands receive heavier bursts, while the remote atolls of the southern group (Farquhar, Cosmoledo, Aldabra) are drier. On a broader scale, global climate cycles like El Niño and La Niña can shift bait migrations and water temperatures, influencing when certain pelagics arrive. Still, the golden rule remains simple: don’t fear the rain. Cloud cover often stabilises conditions, reduces glare, and can create some of the most consistent topwater bites you’ll ever experience.


Fishing seasons in Seychelles


When to come: our favourite months


While Seychelles fishing can be productive any time from October to May, certain months stand out. Based on decades of guiding experience, YFS recommends October, November, December, February, March, April, and May. Each has its particular flavour:


  • October–December: The season opens with vibrant activity as predators feed heavily after the windy period. Expect explosive GT topwater strikes and yellowfin blitzes near bait schools. Blue marlin and sailfish are active, making it a great mixed-bag season.
  • February: Transition month with balanced conditions, a mix of pelagic and reef activity, and one of the best months for travellers seeking comfort and consistent fishing.
  • March–May: The calmest seas and the warmest water. These months are pure glassy perfection, loved by popping and jigging specialists. While some anglers worry that flat calm reduces action, in Seychelles it often means clear sight casting opportunities, stable bait schools, and peak conditions for dogtooth and amberjack on jigs.

In short: anglers chasing trophies should embrace a little unpredictability. Slightly unsettled weather — shifting skies, light rains, or variable breezes — often results in red-hot bites, particularly on topwater and metal jigs.

Target species by season (quick guide)


The Seychelles plateau and drop-off are home to an astonishing mix of reef bruisers and pelagic giants. Here’s how timing influences your chances:


  • Black Marlin: Most active from September–November, though opportunities exist across the season. They follow yellowfin tuna and bonito schools. Techniques: trolling heavy lures, live bait with circle hooks.
  • Blue Marlin: A true year-round predator with a marked increase in September–November. Techniques: trolling large artificials, rigged dead baits, and live skipjack.
  • Sailfish: Present all year, but especially thick during October–November and again in March–April. Techniques: trolling small lures, belly strips, or live bait.
  • Giant Trevally & Bluefin Trevally: Brutal fighters available year-round. Particularly aggressive in October–November just after the windy season, when they hunt ravenously. Techniques: popping, stickbaiting, vertical jigging.
  • Dogtooth Tuna: The most relentless predator on the reef edges — present all season. Techniques: heavy jigging, live bait slow trolling. Prepare for violent runs and frequent bust-offs.
  • Amberjack: Available year-round with peak aggression in April–May. Techniques: vertical jigging in 50–120 m depths.
  • Yellowfin Tuna: A flagship pelagic. Active all year, but the September–November and April–May bites are legendary. Techniques: surface popping, trolling, live bait drift.
  • Wahoo & Mahi-Mahi: Year-round speedsters that love current lines and floating debris. Techniques: high-speed trolling, fast casting along rips and ledges.

YFS tip: Focus on plateau drop-offs for reef giants, and the outer ledge for marlin. Dolphin pods often mean yellowfin nearby — don’t miss the chance to cast poppers into the chaos.


Target species Seychelles


Seychelles fishing by base: catamaran vs lodge


From a catamaran: The most versatile and adventurous option. With YFS, you’ll fish prime months October–May with a full crew: captain, skipper, and fishing guide. Trolling tackle is included, while popping and jigging gear can be brought or rented. Catamaran expeditions allow you to sleep close to the fishing grounds, reach remote atolls, and adapt daily plans to conditions. It’s the ultimate freedom for anglers who want to combine luxury cruising with hardcore fishing.

From a fishing lodge: A great choice for anglers who prefer land-based comfort. From October to May, we offer lodge packages with daily departures, oceanfront accommodations, and competitive pricing. Lodges are perfect for groups or families who want fishing combined with diving, island tours, and relaxation. YFS also collaborates with select hotels to arrange tailor-made fishing itineraries directly from the beach or private jetty.

Recommended techniques & tackle by season


To maximise success, match your technique to the season and species. Seychelles fishing rewards those who prepare the right gear:


  • Popping: The signature technique for GT, yellowfin, and dogtooth. Heavy-duty tackle is essential — PE10 rods, reels with 25+ kg drag, and strong split rings/hooks. Work large cup-faced poppers with a rhythm: sweep, pause, retrieve. Expect violent surface strikes.
  • Jigging: Vertical, speed, or slow pitch. Run 100–400 g jigs across depths from 30 to 200 m. Gear rated to 10–12 kg drag (PE7–PE8) is optimal. Species: dogtooth, amberjack, grouper, and snapper. Stay ready — strikes come without warning.
  • Trolling: Classic blue-water fishing, effective for marlin, sailfish, wahoo, and tuna. YFS provides all tackle, outriggers, and spreads. Ideal for first-time offshore anglers as well as seasoned big-game hunters.
  • Live bait: The ace card for tough days. Rig bonito, rainbow runner, or scad for marlin, big yellowfin, giant dogtooth, or even massive grouper exceeding 200 kg. Requires heavy leaders and strong terminal tackle.

 


Why time your trip with YFS?


Fishing success in Seychelles is about more than luck. YFS designs each expedition around seasonal winds, tides, sea temperatures, bait migrations, and predator behaviour. This precision means you’re always in the right place at the right time, with the right tackle and guidance.

Book your Seychelles fishing in the right season


For anglers seeking calm seas, warm water, and peak predator activity, the choice is clear: October–May. Within this window, October–December delivers intense mixed action, while March–May provides the calmest seas and incredible jigging and popping opportunities. With YFS – Yachting Fishing Specialist, you can choose between a catamaran fishing charter for mobility and adventure, or a lodge-based program for comfort and routine.
