Sailfish.
Winter NE wind = Stream sail bite. Kite fishing's apex.
How they feed in the Keys
The Atlantic sailfish run through the Florida Keys is one of the iconic billfish fisheries in the world. December through March, hard NE winds push sails south against the northbound Gulf Stream, and the fish stack on the 80–250 ft edge from Islamorada through Key West. Kite fishing with live goggle eyes or threadfin herring is the technique — a 30–50 lb sailfish hooked on a kite-suspended live bait is unforgettable. Spring runs slow but persistent activity continues into May.
72–80°F
Active 68–84°F
Less direct (offshore).
Strong Stream flow concentrates fish along edges and color changes.
NE WIND IS EVERYTHING. 12–25 mph NE wind = epic kite fishing. Calm = scattered fish.
Falling pressure intensifies the bite. NE wind events and falling pressure usually coincide.
9 am – 3 pm peak.
Moderate lunar correlation.
Less direct.
Wind from the NE pushing south against the northbound Stream creates the bait stacking that drives the sail bite. South wind shuts the bite down — the bait disperses.
Kite fishing keeps live baits at the surface and visible to circling sails. 4 baits up = highest hookup probability. Add flat-lined baits for redundancy.
12-month outlook
What they eat, what catches them
Live goggle eyes
The premium kite bait. 8–12" goggle eyes on a 7/0 circle hook, kite-suspended.
Live threadfin herring
Reliable and durable. The everyday kite bait when goggle eyes are unavailable.
Live blue runners
Tough and lively — backup kite bait or flat-lined bait.
- Trolled ballyhoo· Search method when not kite fishing. Skirted on Islander.
- Squid chains + ballyhoo· Multi-bait teaser presentation behind the boat.
- Kite day, 15 mph NE wind
2 kites + 4 lines on goggle eyes/threadfins. Drift along 100–180 ft edge.
- Calm day, no kite
Slow-trolled live baits + flat-line ballyhoo behind the boat.

Stand-up class billfish rods. Kite rods separate.
60–80 lb fluorocarbon, 8–12 ft.
- Kite fishing
Stand-up 30 lb class + 30 lb mono + 60 lb fluoro + 7/0 circle + live goggle eye on a kite line. 2 kites with 2 baits each.
Recreational rules
63" fork length minimum (Atlantic).
1 per harvester per day; 1 per vessel per day in many situations.
Open year-round; HMS Atlantic permit required.
Federal HMS regulations apply. Most sails are released — IGFA-record harvests rare.
Note · Atlantic billfish require an HMS permit (free online from NOAA). Almost all sailfish are released; the harvest is impractical for the fish's value as a release-and-revive trophy.
What actually moves the bite
Each factor is rated by how much it shifts the bite for this fish in the Keys. Calibrated against the Bite Score weights — see the Bite Score reference for what each factor measures.
