Tides
The harbour has a maintained depth of 13.7m (45ft) at MLT throughout the main shipping channel and 14.3m (47ft) in the entrance channel. However, 1.5m (5ft) to 1.82m (6ft) tidal lift provides even deeper access for several hours during the day before and after High Tide. A dredging project is nearing its end to make these channels deeper.
Average range 1.5m-1.8m; average current 1.5kts.
At Lightbuoy 'C' (23°37.1'N 079°35.5'W), the tidal stream is rotary, turning clockwise. The maximum rate of the ingoing streams occurs about 3.75 hours before HW at Charleston, when it sets about 270°at an average rate of 0.25kts. The maximum rate of the outgoing stream occurs about 3 hours after HW at Charleston.
Between the jetties the tidal streams generally follow the direction of the channel near its axis. Outside the entrance it branches from the main outgoing stream setting through the openings between the outer part of the jetties and the coast at a rate of 2kts. The maximum rate of the outgoing stream is about 3kts between the outer part of the jetties, and between Fort Moultrie and Fort Sumter (32°45.0'N 079°52.05'W).
At the entrance to Charleston Harbour, between the jetties, slack water before ingoing stream occurs about 5.5 hours before HW at Charleston, slack water before the outgoing stream, about 0.5 hours after HW there.
The outgoing stream in South Channel attains a maximum rate of 2kts. The rate of the ingoing stream is less than the outgoing, depending on the flow in the river caused by precipitation.

About Charleston
updated Sep 2026Where it is
The port of Charleston is located in the centre of the US Eastern Seaboard in the State of South Carolina.
The port
Charleston is the deepest harbour on the South East Coast of the USA with a maintained depth of 13.7m (45ft). Upon completion of its project to take depths to 15.8m (52ft), the port will be the deepest harbour on the East Coast. Facilities are readily accessible by day or night in clear weather, naturally protected by barrier islands on either side of a wide entrance channel; an excellent harbour of refuge. The port has five terminals and deals extensively with container traffic, breakbulk cargo and cruise passengers. Preparation work has already started on a sixth major container terminal. There are also plans for a three mile extension of the Entrance channel, dredged to 16.5m.
Following the opening of the New Locks at the Panama Canal, the port has experienced an increase in the number of larger vessels using its facilities.
Traffic
Approx 1,000,000t of cargo, 2,600,000TEU, 1,800 vessels and 225,500 passengers handled annually.
