On This Water

Florida · Middle Keys / Marathon

Hogfish are the hunt — wait for the next push under the bridges. Heat is the clock — first light or last light.

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

  • Extreme water temperature. Fish stress quickly — keep them wet, or don't boat them.
  • Thunderstorms in the forecast. Lightning is a stay-tied call. The score is not a safety brief.
  • 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.

Why — and who

  • Tide is high slack from NOAA.
  • Observed water is close to the astronomical prediction — the table is telling the truth today.
  • Water 91.0°F. Heat is the locator: early, late, deeper.
  • Thunderstorms · 14%. Lightning is a stay-tied call.
  • Wind 4 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.
