Flat, warm water (22-26°C). Sandy, shallow bottom (0.5 to 1.5 m). No waves. No currents in normal conditions. Fresh to brackish water. Ideal conditions for learning kite and wingfoil.
Access from the N2 or the coastal road north of Durban, near King Shaka Airport. Parking at the lagoon edge. Some shops and restaurants nearby. Kite schools on site.
The dominant wind is the NE (summer trade wind), which blows directly onto the lagoon. This thermal wind strengthens in the afternoon and offers reliable 15-25 knot sessions. The lagoon is well exposed to NE wind. Rideable year-round, best October to April.
Few dangers in the lagoon. Be cautious if the river mouth is open to the sea (currents). Hippos occasionally reported in the lagoon (rare but check with locals). Power lines in some nearby areas. Solo sailing not recommended.
