Sebastian Inlet Hits Rare Negative Tide Tuesday

A 0.1-foot morning low and -0.3-foot evening drop will concentrate baitfish, drawing snook and redfish to jetties for prime fishing in Indian River County.

The water at Sebastian Inlet will drop to near-zero Tuesday — and then some.

NOAA CO-OPS tide predictions show two notable lows bracketing the day: a 0.1-foot low at 6:45 a.m. and a –0.3-foot low at 6:53 p.m. That negative evening reading — meaning the water falls measurably below the average low-water mark — signals an especially strong tidal pull through the inlet's narrow cut, the kind of condition that concentrates baitfish and draws snook, redfish, and jack crevalle into predictable feeding positions along the rocks and jetties.

The day's tidal cycle in full:

High: 12:23 a.m. — 3.2 ft Low: 6:45 a.m. — 0.1 ft High: 12:31 p.m. — 2.6 ft Low: 6:53 p.m. — –0.3 ft

The 3.2-foot overnight high gives way to that sharp morning drop, creating a strong outgoing current through the inlet during the early hours — a prime window for anglers working the south jetty on the outgoing tide before sunrise. The afternoon high of 2.6 feet, lower than the overnight peak, reflects the semi-diurnal inequality common along Florida's east coast, where the two daily high tides are rarely equal in height.

Anglers and waders should time their approach carefully around the evening low: negative tides expose more structure and concentrate fish, but also shorten the safe wading margin near the inlet's fast-moving channel. Boaters transiting the inlet should allow extra clearance over shallow bars during both low-tide windows.

Tide times and heights at Sebastian Inlet will differ from those at Fort Pierce or Stuart on the same date due to differences in coastal geometry, inlet configuration, and the timing of the tidal wave as it moves along the coast. Local NOAA station data is always the most reliable guide for planning on the water.

Tuesday's tidal setup at Sebastian Inlet offers one of the more productive natural fishing windows of the week. Forecasters said to consult NWS Melbourne's Zone Forecast Product for any weather conditions that could affect safe access to the inlet.
