Today's Tide Times in Big Coppitt Key

Today in Big Coppitt Key, high tide arrives at 4:41 AM (1.4 ft) and again at 4:56 PM (1.7 ft), and low tide bottoms out at 12:44 AM (0.1 ft) and again at 12:43 PM (0.1 ft). That's a 1.6-foot swing — a gentle neap-cycle swing, so focus on dawn and dusk rather than mid-tide current.

The sun rises at 7:01 AM and sets at 8:00 PM, under a waxing crescent (5% illuminated). With the moon near its spring-tide phase, expect stronger-than-average water movement all week.

Tomorrow starts with a low tide at 1:18 AM (0.1 ft) — see the 7-day outlook below to plan the week.

Tarpon

Megalops atlanticus

Active now

Season: April – August migration

Lutjanus griseus

Active now

Season: Year-round, best in summer

Baits: Live shrimp, Pilchards, Cut bait on light leader

Common Snook (Centropomus undecimalis)

Common Snook

Centropomus undecimalis

Active now

Season: March – October (check season closures)

Baits: Live pilchards, Swimbaits, Topwater plugs

Work dock lights, mangrove edges, and passes on moving water. Summer beach snook cruise the first trough at first light.

Bonefish (Albula vulpes)

Bonefish

Albula vulpes

Slowing

Season: Spring and fall, tide-dependent

Baits: Live shrimp, Small crabs, Bonefish jigs

Pole or wade the flats on a flooding tide and look for tails and nervous water. Long, quiet casts — the gray ghost spooks at shadows.

Permit (Trachinotus falcatus)

Permit

Trachinotus falcatus

Slowing

Season: Spring and fall on the flats

Baits: Live crabs, Crab flies, Small jigs

A live crab drifted ahead of a tailing fish is the classic play. The most maddening — and most rewarding — fish on the flats.
