Corsica

Corsica sits in the Mediterranean west of Italy, and its tidal regime is about as quiet as coastal waters get. Spring range runs 0.25–0.35 m, making the lunar tide nearly invisible against everyday wave action. What actually moves sea level here is the weather: the tramontane off the French mainland and the libeccio from the southwest can push or pull the waterline by 0.3–0.5 m, swamping the astronomical tide entirely. Ajaccio Bay on the western coast offers sheltered anchorages and clear water over posidonia seagrass meadows at 5–15 m depth. Bastia guards the northeast corner near Cap Corse, exposed to Ligurian Sea tramontane swells. Porto-Vecchio in the south opens onto a sheltered gulf and gives access to Palombaggia beach and the Strait of Bonifacio 20 km further south, where tidal currents reach 5 knots in the narrows. Snorkellers, freedivers, sailors, and families all find what they need here — as long as they watch the weather, not the tide table.
