On This Water

Florida · Lower Keys / Key West

Permit should be the day — wait for the next flood after the shower clears.

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

Where

This pip is that mark on this tide — not the day on the ring.

  • Marquesas

    hard flat · field manual · skinny

    6.9

    Long run, fewer boats. Permit country. Weather window or you don't go.

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 low slack from NOAA 8724580 Key West.
  • Clear. Sky is workable.
  • Wind 8 mph SE. Castable. Sight-fishing is on if the sun is out.
  • Waxing gibbous moon — neap tide range. Sight water often prefers a moderate range and clean water over a huge spring.
