Semaphore is a protected beach break located on the northern coast of Adelaide, South Australia, facing northwest into Gulf St Vincent. The spot features a sandy beach with gentle shelving and a recreational pier structure. Water conditions are typically choppy rather than organized swell, with very small average wave heights. The area receives moderate foot traffic from swimmers and casual beach users. Wind conditions are marginal, with low reliability (13.6%) and modest average winds of 7.8 knots. Best conditions occur with northeast winds providing side-shore orientation. The spot suits beginner and novice kiters seeking flat-water freestyle practice or light-wind sessions, though consistent wind is not guaranteed. Water temperature averages 17.3°C, requiring thermal protection. Key considerations include navigating the pier, avoiding swimming areas during peak times, watching for shallow water and seagrass, and accepting that many days will lack sufficient wind. This is primarily a fair-weather spot best suited for practice during rare consistent wind windows.
