Tarquinia is a shallow lagoon system on the Tyrrhenian coast of central Italy, characterized by protected waters bordered by agricultural fields and residential developments. The lagoon spans multiple segments separated by land, with depths typically under 2 meters throughout. The spot offers light-wind conditions with an average of only 6.9 knots and poor wind reliability at 10.3%, making it challenging for consistent kitesurfing sessions. Water temperatures average 17.3°C with minimal wave energy (0.60m average). The lagoon's protected nature and shallow depths make it suitable for beginners when wind conditions align, particularly with easterly winds providing side-shore conditions. However, the combination of very low wind availability, shallow water requiring careful board handling, residential proximity, and boating activity limits utility as a dedicated kitesurfing venue. Best conditions occur with sustained easterly winds during spring and autumn seasons. The spot is primarily suitable for learners seeking calm-water practice in light winds, though frequent flatwater sessions should be anticipated.
