Bordj Kastil is a sheltered lagoon system located on Tunisia's Mediterranean coast, separated from open water by sandbars and narrow tidal channels. The satellite imagery shows a elongated lagoon with bright green water indicating shallow depth and algae content, connected to the sea through a constrained inlet on the northeastern side. The water body is bordered by salt marshes, sandy banks, and low-lying terrain. With average wind speeds of only 7.6 knots and extremely low wind reliability at 9.8%, this spot experiences marginal wind conditions for kitesurfing. The lagoon's shallow, protected waters (0.29m average wave height) make it suitable only for beginner-level riders during rare windy periods. Best conditions occur with northwest winds (315°) providing side-shore conditions. The restricted fetch, shallow depth, and tidal channel constraints limit progression potential. Strong currents may develop through the inlet during tidal transitions. This location is better suited for light-wind training or alternative water sports rather than regular kitesurfing. Access and water conditions vary significantly with tidal cycles.
