Stuart Tide Schedule: Tuesday, May 19, 2026

TODAY: Four tides shape Tuesday on the Treasure Coast, with a near-zero low at 4:44 a.m. giving way to a modest 2.8-foot high tide at 10:40 a.m., the National Weather Service tidal data shows.

TONIGHT: The evening builds toward the day's strongest water movement — a 3.4-foot high tide crests at 11:26 p.m., making tonight one of the fuller tidal swings of the current lunar cycle, according to NWS CO-OPS data for Stuart.

THIS WEEK: Tuesday's negative afternoon low of -0.5 feet at 4:48 p.m. is the standout figure in this tide window. Negative readings expose oyster bars, shallow grass flats and tidal creek mouths along the St. Lucie River — conditions that concentrate baitfish and draw feeding snook and redfish into predictable kill zones. Boaters in shallow-draft vessels should note that docks, ramp approaches and the sandbar near the Roosevelt Bridge will sit lower than normal during that window.

ON THE WATER: The 4:48 p.m. negative low is the tactical anchor for anglers Tuesday. As water drains off the grass flats along the South Fork of the St. Lucie, baitfish — pilchards and juvenile mullet in particular — stack at creek mouths and channel edges. Work a live pilchard on a light jig head along those ambush points in the 30-minute window before and after dead low for the best shot at snook holding in the shadow of the outgoing current. Target the flats east of Leighton Park and the channel mouth at Willoughby Creek for the most consistent action during this tide phase, which mirrors productive afternoon low conditions from the same week last year.

ALERTS: No active NWS watches, warnings or advisories are in effect for Martin County at time of publication.
