On This Water

Florida · Miami / Biscayne Bay

Permit are the hunt — the ocean banks as they empty; these fish are educated and the window is short. Heat is the clock — first light or last light.

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.

  • Extreme water temperature. Fish stress quickly — keep them wet, or don't boat them.
  • Snook are typically closed to harvest on the SE/Atlantic coast in this window. Verify FWC.

Why — and who

  • Tide is outgoing from NOAA.
  • Observed water is close to the astronomical prediction — the table is telling the truth today.
  • Water 90.3°F. Heat is the locator: early, late, deeper.
  • Partly cloudy. Clouds steal the window on bones and permit.
  • Wind 4 mph SE. Castable. Sight-fishing is on if the sun is out.
  • Waxing gibbous moon — mid tide range. Sight water often prefers a moderate range and clean water over a huge spring.
