Newfoundland

Newfoundland's Atlantic coast faces the open North Atlantic with nothing between it and Europe, and the tides make that clear. Tidal patterns are semidiurnal — two highs and two lows each day — with mean ranges varying from approximately 1.3 metres at St. John's to 1.8 metres on the Bonavista Peninsula. Storm surge can add or subtract a metre on top of the predicted height when North Atlantic cyclones track close to the coast; the Narrows at St. John's, a 200-metre-wide channel between Signal Hill and the South Side Hills, funnels surge energy into the harbour. The physical setting defines everything. Cape Spear, 10 kilometres south of St. John's, is the easternmost point of North America; standing at the lighthouse, the next landfall east is Portugal. Iceberg Alley brings calved Greenland glaciers south along the Labrador Current from March through July — icebergs are visible from shore on the Avalon Peninsula, some grounding offshore near Twillingate and Bonavista. Puffin colonies at Cape St. Mary's and surrounding headlands draw summer visitors tracking the same coastline the birds have nested on for centuries. The cod fishery shaped Newfoundland's outport communities for 500 years before the federal moratorium in 1992. Twillingate, Bonavista, and dozens of smaller harbours still carry that identity — the stages, the flakes, the orientation of every building toward the sea and the boat. Tide times matter for harbour entry and departure at low-water outports as much today as they did then. Tide predictions on this site come from Open-Meteo Marine (±45 min / ±0.2–0.3 m accuracy). For authoritative official Canadian predictions, consult DFO — Fisheries and Oceans Canada's Canadian Tidal Prediction Service (tides.gc.ca).
