About This Spot
Koper-Zusterna is a shallow bay location on Slovenia's Adriatic coast, facing northeast toward open water. The spot sits within a developed coastal region with residential areas extending to the shoreline, limiting maneuvering space. This is a protected bay environment with significant boat traffic visible in the anchorage area, indicating commercial and leisure vessel activity. Wind conditions are marginal, with extremely low reliability (1.6%) and minimal average wind (4.2 knots), making it challenging for consistent kitesurfing sessions. Water is flat with minimal wave generation due to bay protection and limited fetch. Side-shore winds from the northwest (315°) would be ideal but rarely occur. The shallow water and proximity to infrastructure require careful navigation. This spot suits only beginners on rare high-wind days and is better suited for windsurfing or other light-wind disciplines. The combination of shallow water, boat traffic, and poor wind statistics makes this a marginal kitesurfing destination. Local conditions and seasonal variations should be verified before attempting sessions.
