On This Water

Florida · Middle Keys / Marathon

Bonefish should be the day — Seven Mile current and the oceanside patches — permit and tarpon, not a bonefish morning.

Vaca Key gauge. Oceanside wrecks and patch reefs, bayside basins, Seven Mile Bridge current. Permit and tarpon more than bones.

  • This brief is for 2026-12-20, not this morning. Wind is a forecast. Observed water versus the table is a today-only instrument.
  • Snook are typically closed to harvest on the SE/Atlantic coast in this window. Verify FWC.
  • FKNMS no-take water in this box: Sombrero Key, Coffins Patch. The red polygons are the legal source — do not fish them.

When

When is moving water in a good hour — not the day. Today’s ring mixes the best mark, the lead fish, and the best window, then taxes the sky. A strong incoming can sit under a weak day if the wind or the fish is off. Calendar cells are a third recipe: range, moon, and the day’s forecast.

Why — and who

  • Tide is incoming from NOAA 8723970 Vaca Key, Florida Bay.
  • Overcast. Sky is workable.
  • Wind 6 mph SE. Castable. Sight-fishing is on if the sun is out.
  • Waxing gibbous moon — mid tide range. Marsh and passes usually want the extra current of a spring.
