On This Water

Florida · Miami / Biscayne Bay

Permit should be the day — oceanside banks for bones and permit — west-side mangroves for baby tarpon and snook. Work the leeward shore — fly gets harder.

North end of the grand-slam stage. Bones and permit on the oceanside flats and ocean banks, baby tarpon and snook in the west-side mangroves. Educated fish, short windows, boat traffic.

  • Small-craft wind. The score is not a safety brief.
  • Snook are typically closed to harvest on the SE/Atlantic coast in this window. Verify FWC.

Why — and who

  • Tide is incoming from NOAA.
  • Rain · 26%. Sight water goes blind. Wait it out or switch to stained marsh.
  • Wind 27 mph S. This is a spin / structure / stay-home call.
  • Waxing gibbous moon — spring tide range. Sight water often prefers a moderate range and clean water over a huge spring.
