Canadian Marine & Tides
Real-time coastal oceanography across Canada's Atlantic, Pacific, and Estuary waters. Explore semidiurnal tidal waveforms, high/low astronomical predictions, sea surface buoy temperatures, and ocean swell periods.
Hopewell Cape & Burntcoat Head (Bay of Fundy)
Bay of Fundy / Minas Basin • New Brunswick / Nova Scotia • Coordinates: 45.82°N, 64.57°WSemidiurnal Tidal Water Level Curve
Relative to Chart DatumNavigational Advisory
Rapid tidal bore advance. Walkers on the ocean floor must exit 3 hours before high tide.
Highest tidal resonance in the world with 160 billion tonnes of seawater flushing twice daily.
Bay of Fundy Resonance
The Bay of Fundy’s natural oscillation period (~12.5 hours) matches the Atlantic ocean’s tidal pulse, creating acoustic-like standing wave resonance with world-record vertical shifts exceeding 16 meters.
Pacific Swell Dynamics
Groundswells reaching Vancouver Island and Tofino are generated by deep North Pacific low-pressure systems thousands of miles offshore, compressing kinetic wave energy as water shallows over continental shelf breaks.
Atlantic Advection Fog
Warm, moist tropical Atlantic air drifting northward over the cold southward-flowing Labrador Current rapidly condenses into dense marine sea fog blanketed across the Nova Scotia and Newfoundland coasts.
