The current usually sets south-south-eastwards in the approach to Port Said at a rate of 0.5 to 1.5 knots, but is very uncertain, depending on the wind. Caution is therefore necessary when approaching the port and the entrances to the Suez Canal. In the Canal, there are current buoys indicating the direction of the current : Head Current : Red & White horizontal bands or 1 reflector at night. Stern Current : Black & White vertical stripes or 2 reflectors at night.
