Sailfish sea surface temperature guide.
Sailfish are the SE Florida winter fishery and a Gulf summer presence. The SE FL bite is concentrated December through March when the Gulf Stream pushes close to shore and bait stages along the temperature break.
SST threshold gauge
The water temperature ranges that determine where sailfish hold and feed. Hard thresholds (dashed lines) are values outside which fish actively depart or become inactive.
Depth profile & SST reliability
Sailfish feed at the surface and are well-predicted by SST. Look for warm water and bait.
Current systems & structure
Atlantic sailfish in SE Florida concentrate when the Gulf Stream pushes close to shore in winter — December–March is the peak window. Gulf Coast sailfish run summer–early fall.

Zone-by-zone calendar
For each zone where sailfish are present, the chart overlays the zone's typical monthly SST range with the species' preferred and optimal ranges. Months where the bands overlap are when fish are in range.

Conservation & regulations
Stable (Atlantic) — managed by ICCAT. Catch and release standard. Atlantic minimum size 63 inches (lower jaw fork length) for retention; HMS permit required.
Stock assessment source →Kite fishing live goggle eyes and threadfin herring is the SE Florida winter standard. Slow-troll dink ballyhoo on weed lines in summer. Find sails on the cool edge where they push bait against the Gulf Stream.
