Target species: Giant Trevally, Bonefish, and Permit.

About this Water

The outer atolls of the Seychelles — Cosmoledo, Farquhar, and Providence — represent the apex of saltwater fly fishing for giant trevally. These remote Indian Ocean atolls are accessible only by liveaboard, ensuring pristine fishing conditions and fish that have seen extraordinarily little pressure. GT to 50+ lbs cruise the shallow coral sand flats hunting bonefish, triggers, and anything else that crosses their path — the predatory spectacle is unequaled in saltwater fishing.

Giant trevally on the Seychelles atolls are apex predators in a near-pristine ecosystem — they actively hunt bonefish on the flats in groups, creating the most spectacular feeding displays in all of saltwater fly fishing.

January Outlook

January at the Seychelles outer atolls is an excellent fishing month. The season continues from October through March. GT, bonefish, permit, and triggerfish are all active on the pristine Indian Ocean flats of Cosmoledo, Farquhar, and Providence atolls. The liveaboard is the sole access to these remote islands.

Productive Patterns

  • GT Popper (large)
  • EP Minnow (large)
  • Crab Pattern
  • Clouser (large)

Tips

January is mid-season at the Seychelles atolls. Weather is hot and typically calm. GT fishing early morning is exceptional — fish the flat edges at first light. The guides from Fly Fish Seychelles operate the liveaboard and have mapped every productive flat.

Water Notes

Water 84-90°F. Indian Ocean summer. Warm and generally calm. Some rain squalls possible. All species active.

February Outlook

February continues excellent Seychelles atoll fishing. The season is approaching its finale as the SE trade winds are still weeks away. GT are at their most territorial in February — the best month for multiple double-digit fish in a day. Bonefish and trigger provide additional sport throughout.

Productive Patterns

  • GT Popper
  • Large Crab Pattern (GT)
  • Bonefish Fly (#4)
  • Trigger Crab (small)

Tips

February produces some of the year's finest individual GT encounters. Fish are large and aggressive. The combination of species makes these atolls unlike anywhere else — GT, bonefish, permit, trigger, and bumphead parrotfish all present.

Water Notes

Water 84-90°F. Late summer conditions. Warm, mostly calm. GT at peak aggression. Season closing in 4-6 weeks.

March Outlook

Final month before SE trade winds close most atolls. Outstanding late-season GT fishing on Cosmoledo. Season ends late March on most operations.

Productive Patterns

  • GT Popper
  • Large Clouser
  • EP Minnow
  • Crab Pattern

Tips

The approaching trade wind season creates some of the most productive GT fishing of the year — fish are feeding heavily before conditions change. The last two weeks of March are often excellent.

Water Notes

Water 86-90°F. Pre-trade wind. Some early winds starting. Late-season fishing before atoll access closes.

April Outlook

April — the Seychelles outer atolls close to fly fishing liveaboards as the SE trade winds establish. The remote atolls are inaccessible in trade wind conditions — the exposed flats and anchorages become unsafe for the liveaboard vessels. The exceptional October-March season has ended. Planning for October reopening begins.

Productive Patterns

  • Post-season — book October Seychelles liveaboard
  • Season closes late March/early April
  • Contact Fly Fish Seychelles for next October availability
  • Prepare 12-weight GT outfits for next season

Tips

Book the following October immediately — the Seychelles liveaboard has very limited berths and the finest weeks (November) sell out months in advance. Cosmoledo Atoll is considered one of the top three GT fisheries in the world.

Water Notes

Season closed. SE trade winds established. Atolls inaccessible. Season reopens October. Book now.

May Outlook

May — full SE trade wind season. The Seychelles outer atolls are exposed and the liveaboard operations are closed. The GT and bonefish are undisturbed on the pristine Indian Ocean flats. Five months until the October reopening. The closed season is what keeps the fish populations extraordinary.

Productive Patterns

  • Planning season — 5 months to October
  • Book Seychelles liveaboard berths for next season
  • Prepare 12-weight GT tackle and 8-weight bonefish setups
  • Tie large GT crab patterns and EP minnows

Tips

The Seychelles atolls are among the world's least-pressured saltwater fisheries specifically because the trade wind season keeps them inaccessible for 6 months per year. The result is fish that have never seen a fly — explosive strikes from very large, completely unpressured GTs.

Water Notes

Season closed. Trade wind season. Atolls inaccessible. Season reopens October 1.

June Outlook

June — mid-trade wind season. The Seychelles outer atolls are inaccessible. The SE trade winds lash the Indian Ocean at this time of year with consistent 25-35 knot winds. The liveaboard is in the main Seychelles harbor for maintenance. October is 4 months away.

Productive Patterns

  • Planning season — 4 months to October
  • Confirm liveaboard bookings for October-March season
  • Research Seychelles permit and visa requirements
  • Tie GT poppers and large crabs for next season

Tips

The liveaboard operators use the trade wind season for vessel maintenance and crew rest. Book through operators who have long track records at Cosmoledo and Farquhar — these remote atolls require specific knowledge that takes years to develop.

Water Notes

Season closed. SE trade winds at full strength. All atolls closed. Season opens October.

July Outlook

July — the trade wind season continues. The Seychelles outer atolls are inaccessible for another 3 months. The GT are undisturbed, the bonefish and trigger are feeding in complete isolation. October bookings should already be confirmed — if not, act immediately.

Productive Patterns

  • Planning season — 3 months to October
  • All prime October and November slots should be booked
  • Final gear preparation: 12-weight and 8-weight outfits
  • Prepare strong GT leaders: 80-100 lb shock tippet

Tips

The logistics for a Seychelles atolls trip are straightforward: fly to Mahé (Seychelles capital), join the liveaboard, and let the vessel do the rest. The primary planning element is securing the liveaboard berth — do this years in advance for peak November weeks.

Water Notes

Season closed. Trade wind season. 3 months to October opener. All major bookings should be confirmed.

August Outlook

August — the SE trade winds are moderating. The outer atolls are beginning to become accessible to weather. The liveaboard is completing final preparations for the October season opener. The extraordinary GT fishing of November is 3 months away. Final preparations for this season.

Productive Patterns

  • Planning season — 2 months to October opener
  • Liveaboard preparing for the season
  • Confirm all October and November arrangements
  • Prepare anti-corrosion reel maintenance before salt exposure

Tips

August is the final preparation month for the Seychelles season. Confirm all visa arrangements, check Seychelles entry requirements, and finalize tackle preparation. The fishing at the outer atolls is exceptional and worth every preparation effort.

Water Notes

Season approaching. Trade winds moderating. Atolls becoming accessible. Season opens October. Prepare now.

September Outlook

September — the last month before the Seychelles outer atolls reopen. The SE trades have largely subsided. The GT, bonefish, and triggerfish have had 6 months of undisturbed feeding on pristine Indian Ocean flats. The liveaboard is fully operational and repositioning for October access. The fish are going to be extraordinary.

Productive Patterns

  • Planning season — season opens October 1
  • Final tackle check: 12-weight for GT, 8-weight bonefish
  • The atolls are reopening — anticipation at maximum
  • Pre-rig outfits and leaders before boarding the liveaboard

Tips

September is the final preparation month. The fish at the Seychelles atolls are completely unpressured after 6 months of zero angling. October guests typically encounter GTs that have never seen a fly — the aggression and size of these fish is exceptional.

Water Notes

Pre-season. Atolls reopening. Season begins October 1. Fish completely unpressured after 6-month closure.

October Outlook

The liveaboard season at Cosmoledo and Farquhar atolls opens in October after the favorable SE trade wind period. Giant trevally to 50+ lbs are the primary target on these remote Indian Ocean atolls.

Productive Patterns

  • Large Clouser Minnow (8/0)
  • EP Minnow (large)
  • Popper (topwater)
  • Crab Pattern

Tips

GTs require extreme power — 12-weight outfits with 80-100 lb leaders and steel or bite-resistant tippet. Casts of 60-80 feet to cruising fish on the flats are standard. The strikes are violent and the runs powerful. Strip-setting is essential.

Water Notes

Water 82-88°F. Indian Ocean. Post-trade wind season. Calmer conditions for flats access. Liveaboard is the only access to outer atolls.

November Outlook

Prime Seychelles GT season. All three premier atolls (Cosmoledo, Farquhar, Providence) fishing at peak. Bonefish, permit, and triggerfish provide additional targets.

Productive Patterns

  • Crab Pattern (large)
  • GT Popper
  • EP Minnow
  • Clouser (large, heavy)

Tips

November is the most productive month for multiple species at the Seychelles atolls. GT feeding on bonefish schools is spectacular — the apex predator chasing prey in clear shallow water. Early morning and incoming tide edges produce best GT action.

Water Notes

Water 84-90°F. Optimal Indian Ocean conditions. Warm, clear, and calm. The best Seychelles month.

December Outlook

Excellent early season at the Seychelles atolls. GT season fully underway. Christmas Island comparison: the Seychelles has fewer bonefish but larger individual GTs.

Productive Patterns

  • GT Popper
  • Large EP Streamer
  • Crab Fly
  • Bunker-style Fly

Tips

December conditions are outstanding. The outer atolls see very few boats and fish are not heavily pressured. Book through reputable liveaboard operators (Fly Fish Seychelles or similar) for the most reliable access.

Water Notes

Water 84-90°F. Early rainy season but typically manageable. Some days may see afternoon squalls.

Access & Approach

Fly to Mahé (Seychelles) then connect to liveaboard vessel. 7-9 day trips are standard. 12-weight outfits with 80-100 lb leaders essential for GT. Seychelles fishing permit included with liveaboard packages. Advance booking 1-2 years standard.
