Big Marco Pass: tide and current notes
Big Marco Pass is one of the 20 inlets and passes Anglrithm measures runs from, in the Southwest Gulf region. This page sets out the public facts about its water: the NOAA tide gauges around it and how their tides run, what is known about its current, and the structure outside it.
How the tide runs here
2 NOAA tide gauges sit within 6 nm of the inlet. Highs are timed against Naples (8725110), the reference for the Gulf coast.
- Marco River CO-OPS 8724991Gulf beach or pass, 1.0 nmMean range 1.9 ft; highs about 52 minutes after Naples.
- Caxambas Pass CO-OPS 8724967Gulf beach or pass, 3.7 nmMean range 2.0 ft; highs about 23 minutes after Naples.
For the water at the mouth Anglrithm reads Marco River (8724991), 1.0 nm away: a gauge on the Gulf beaches or in a pass, never one inside a bay, river or sound, because those run late against the water outside.
From NOAA CO-OPS tide predictions, October 4, 2026 to November 15, 2026: the mean range between successive highs and lows, and the median time from the high at Naples to the high at each gauge. A description of this inlet's tide, not a tide table.
Current
Anglrithm has no NOAA current prediction station on record for this pass, so no page here gives the strength or timing of its flow.
Wind blowing against the current stands the seas up: shorter, steeper and more likely to break than the same wind over slack water, which decides how a drift sets up and how long a day stays fishable. That is physics about the water, not evidence about the fish; no study we found ties it to catch.
U.S. Coast Pilot 4, Chapter 3 (opposing wind and current on the Gulf Stream: sharply higher, steeper seas that can break; mechanism only). No catch study found.
Within 10 nm
73 of the 2,153 wrecks and reefs in the structure file lie within 10 nm of the inlet, from FWC artificial reef program and NOAA Office of Coast Survey charts.
