NOAA CO-OPS current predictions for station ACT4996, speeds in knots at the predicted maximums, station local time. Table generated 2026-10-14; predictions are deterministic, but wind and river flow change the real current.
- NOAA station ACT4996 — official CO-OPS current predictions
- Flood is “up the Bay” (roughly north) at most stations; ebb runs seaward
- Wind against current builds short, steep chop — plan the rough legs for slack
