Swanage tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are Europe/London local. Folk tradition, not a scientific forecast.

Last spring tide on Mon 04 May (range 1.3m / 4.2ft). Next neap on Sat 09 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Swanage is the eastern end of the Jurassic Coast — the UNESCO World Heritage coastal section that runs 154 kilometres westward to Exmouth in Devon. The town sits in a bay cut into Purbeck limestone, with the chalk ridge of Ballard Down to the north and the limestone stacks of Durlston Head to the south. The geological variety within a few kilometres of Swanage is exceptional. Tidal range here is moderate but irregular: the English Channel double-tide pattern is pronounced at Swanage, with mean spring range around 1.8 metres — much less than on nearby Portland or the open Channel coast. The low tidal range at Swanage is largely due to its tucked position in Swanage Bay, which faces southeast. The chalk headlands to the north (Old Harry Rocks) and the limestone headland to the south (Durlston) partially shelter the bay from the full tidal exchange. The result is a beach that doesn't shift dramatically between tides — the sand and shingle beach remains accessible and swimable across most of the tidal cycle. Old Harry Rocks — the chalk sea stacks at the north end of the Purbeck coast — are the most iconic geological feature near Swanage. They're accessible on the South West Coast Path from the village of Studland (6 km walk from Swanage along the coastal path), and visible from kayaks launched from the main Swanage beach. The chalk is actively eroding; large stacks have collapsed in living memory. The passage between Old Harry and Handfast Point by sea kayak is possible in calm conditions and offers a unique perspective on the chalk architecture. Surf at Swanage is limited — the sheltered bay and low tidal range don't produce the conditions that characterise the Atlantic coast. What the bay does reliably well is flatwater paddling and sea kayaking. The chalk and limestone coast from Swanage to Kimmeridge (10 km southwest along the South West Coast Path) can be paddled in a full-day trip, passing caves, arches, and reef systems not visible from land. Kimmeridge Bay is worth singling out: a designated Marine Conservation Zone with some of the best snorkelling and shore diving on the English south coast. The Jurassic reef at Kimmeridge holds dogfish, wrasse, pollack, and lobster. The Purbeck Marine Wildlife Reserve provides information and monitoring; the old Clavell Tower on the cliff above is a landmark. The Swanage steam railway runs from the town centre to Corfe Castle (6 km inland) and on to Wareham on the main rail network — a genuinely functional heritage railway link.
