Permit should be the day — the oceanside wrecks and the falling contentment flats.

Marquesas, Harbor Key, oceanside wrecks, the contentment of long runs. Permit and tarpon country. Summer showers can switch a flat on once it clears.

Why — and who

  • Tide is outgoing from NOAA.
  • Clear. Sky is workable.
  • Wind 8 mph ESE. Castable. Sight-fishing is on if the sun is out.
  • Waxing crescent moon — mid tide range. Sight water often prefers a moderate range and clean water over a huge spring.
