Fort Pierce Tide Schedule: Monday, May 18, 2026

TODAY: Partly cloudy skies are expected across St. Lucie County on Monday, with afternoon high temperatures climbing into the upper 80s. A 30 percent chance of afternoon showers is typical for this point in Florida's transitional pre-rainy season window.

TONIGHT: Warm and muggy overnight, with lows near 74 degrees Fahrenheit.

THIS WEEK: Conditions typical of mid-May on the Treasure Coast — humid mornings, isolated afternoon convection possible by Wednesday as the rainy season pattern builds.

ON THE WATER: Monday delivers one of the more favorable tide windows of the week for anglers and boaters working the Fort Pierce area. The day opens with a modest low at 4:00 a.m., reading minus 0.2 feet at the Fort Pierce gauge, NOAA CO-OPS data shows. The morning flood tide peaks at 2.7 feet by 9:57 a.m. — a solid window for working the jetties or the Fort Pierce Inlet channel as baitfish push in on the rising water.

The day's standout feature is the afternoon low: a sharp minus 0.8-foot drop bottoming out at 4:03 p.m. That deep ebb drains grass flat margins and oyster bars south of the inlet, concentrating snook, redfish, and flounder along defined edges. For wade fishers, the hour just before and just after that 4:03 p.m. low at the South Jetty flats represents the most productive tactical window of the day. Work a live finger mullet or a dark-colored soft plastic along the exposed grass line. The overnight high of 3.4 feet crests at 10:43 p.m., nearly a foot stronger than the morning high, reflecting the characteristic mixed semidiurnal pattern that defines Fort Pierce's tidal rhythm.

Compared to the same week in May 2025, this afternoon low is running roughly 0.2 feet deeper, NOAA tide records indicate — a minor but meaningful difference that exposes additional bottom structure for wading anglers.

ALERTS: No active NWS watches, warnings, or advisories are in effect for St. Lucie County as of this report.
