Why — and who

  • Tide is outgoing from NOAA.
  • Waxing crescent moon — mid tide range. Sight water often prefers a moderate range and clean water over a huge spring.

Bonefish

Albula vulpes

8.4

Thermal window

64°92°

In peak season for this water. This tide stage (outgoing) matches how they hunt.

Florida: catch-and-release only, hook-and-line only.

Permit

Trachinotus falcatus

8.4

Thermal window

66°92°

In peak season for this water. This tide stage (outgoing) matches how they hunt.

Florida: hook-and-line. Special Permit Zone (Keys) is tighter than the rest of the state — typically C&R. Verify FWC.

Tarpon

Megalops atlanticus

6.6

Thermal window

68°94°

Present, not peak. This tide stage (outgoing) matches how they hunt.

Florida: catch-and-release. Fish over 40 in must stay in the water. One harvest tag/year only for a potential IGFA record.
