La Mercy Lagoon

La Mercy Lagoon is a protected lagoon system on South Africa's east coast near Durban, formed by the Tongati River estuary. The lagoon features shallow, calm waters separated from the ocean by a sandy beach and dune system. The coastline faces east toward the Indian Ocean, with the lagoon positioned inland as a sheltered water body. Side-shore winds from the north or south are optimal for kitesurfing, though wind reliability is notably low at 4.5%, making this a challenging spot for consistent conditions. The shallow lagoon (typically 0.5-2m depth) and muddy substrate suit beginners and progression riders seeking protected flat water for technique development. Average wind speeds of 6.4 knots are marginal for kitesurfing. The spot experiences rough water conditions despite lagoon protection, likely due to river outflow dynamics. Tidal timing is critical for water depth and accessibility. Residential development inland and proximity to river mouth currents require careful navigation. Best suited for light-wind practice and skill building rather than wave riding.
