The port is open to the shamal, blowing from the N and NW.
Tides here have a maximum spring range of 2m, while the neap range is 0.1m. Tidal currents in the area tend to follow the coast, with spring rates of less than about 1 knot.
Strong tidal currents have been reported within Mina Zayed and the approach channel; rates of up to 4.5 knots occur within the dredged fairway, with the current setting cross-channel.
The harbor approach channel, extending about 5 miles NW of the island, is dredged to a depth of 15m (2001). Just within the breakwaters, a secondary fairway, dredged to a depth of 11m, joins the main channel and continues to the SE, leading to an offshore supply base within
Khawr al Bighal. The main fairway turns sharply S at the junction of the two channels and leads to Mina Zayed.
Mina Zayed has been dredged throughout to a depth of 15m (2001), except for a spur at its NW end, which has been dredged to a depth of 6m (2001).
There are 21 berths available, handling container, cement, grain, and bulk cargo. Tankers are accommodated at the SE end of the harbor, while ro-ro vessels med-moor to the break-bulk berths to work cargo. Vessels with a draft greater than 11m must take the tide into account when berthing.
It has been reported (2003) that an additional container terminal, with a length of 650m and a depth of 17m alongside, which would accommodate two container vessels, will be constructed in the port.
