Bonavista tide times

Mean tidal range at Bonavista is approximately 1.8 metres — noticeably larger than the 1.3 metre mean range at St. John's. The difference reflects the Bonavista Peninsula's more exposed northeast-facing position and local bathymetry effects. Spring ranges reach approximately 2.2 metres. The practical consequence is that rock platforms at Cape Bonavista are accessible over a wider vertical extent at low water than equivalent features on the Avalon Peninsula, and the tidal change over a 6-hour half-cycle is more dramatic. Iceberg and whale watching from the cape is best at low to mid water when the lower platforms are dry.

The landfall claim for Cape Bonavista is traditional and widely accepted in Newfoundland, supported by the Italian origin of the name ('O happy sight' — a lookout call from the rigging) and the cape's position as a logical first landfall for a vessel crossing from Bristol on the route Cabot would have taken. Most historians treat it as plausible but not definitively proven — some competing theories place the landfall at Cape Breton Island in Nova Scotia or at other points on the Newfoundland coast. The 1843 Cape Bonavista Lighthouse stands at the claimed spot; the Ryan Premises National Historic Site and the Matthew replica at the waterfront mark the 500th-anniversary commemorations from 1997.

Icebergs pass Cape Bonavista from late March through early June; the peak concentration is typically late April to mid-May. The cape faces northeast into the Labrador Current transport corridor, making it one of the better shore-based iceberg viewing points on the northeast Newfoundland coast. Humpback and minke whales follow capelin inshore from July through September; the cape and the coastal trail offer good vantage points. Puffins and other seabirds are present at offshore rocks from May through August. For a single trip that covers icebergs, whales, and puffins, late June to early July is the statistical overlap window, though iceberg numbers decline by then.

At low water, the rock platforms at the base of Cape Bonavista are accessible from the lighthouse path — the exposed surface is wave-cut quartzite and sandstone, polished smooth and pitted with tidal pools. The full geometry of the wave-cut notch and cliff undercut is visible at low water; at high water the lower platforms are submerged and the sea reaches the base of the cliff face directly. Sea stacks immediately offshore from the cape are most dramatic when partially exposed at low to mid tide. The lighthouse platform above gives the iceberg-watch vantage regardless of tide. On a northeasterly swell at high water, the lower rock platforms are not safe on foot.

No. The predictions shown here come from Open-Meteo Marine, a global ocean model with typical accuracy of plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height. They are suitable for planning rock platform walks, timing iceberg viewing from accessible shore positions, or understanding the general tidal cycle — not for vessel navigation, harbour entry, or any decision where precise tide heights are safety-critical.

Storm surge from North Atlantic cyclones can significantly exceed predicted heights on this open-coast northeast-facing shoreline.
