CURRENTS Currents are irregular, being influenced by the wind, with rates of up to 2 knots. Easterly sets are frequent but strong east winds in spring and autumn can reverse the flows. A very strong current sometimes sets north-east about 1 mile off the entrance to Marsaxlokk. For further information, see Admiralty Sailing Directions. MARINE FARMS Marine farms may exist within this area. They may not all be shown individually and their positions may change frequently. Marine farms may be marked by lit or unlit buoys or beacons. Mariners are advised to avoid these structures and their associated moorings.
