Wanderlust World Wanderlust World The Atlantic Ocean claims the world's highest tides—specifically at the Bay of Fundy (Nova Scotia/New Brunswick), where the tidal range reaches 16.3 meters (53.5 feet). The Pacific Ocean's maximum tidal range is approximately 2 meters (6.6 feet).
Basin resonance: The Bay of Fundy's length (~270 km) and shape create near-perfect quarter-wave resonance with the Atlantic's 12.4-hour semidiurnal tide period. Each incoming tide reinforces the standing wave.
Funneling geometry: The bay narrows and shallows dramatically, concentrating tidal energy into decreasing cross-section.
Pacific tides are generally mixed (two unequal highs/lows daily) with smaller ranges. Exceptions exist: Korea's Incheon (~10m), Argentina's Patagonian coast (~10m), but these are localized amplifications, not basin-scale resonance.
Fundy's extreme tides create unique ecosystems (mudflats, salt marshes), enable tidal power (Annapolis Royal Generating Station), and demand specialized navigation. The Pacific's modest tides simplify coastal engineering but offer less renewable energy potential.
Ocean basin geometry—not ocean identity—determines tidal extremes. The Atlantic happens to host the resonant basins that amplify tides to world-record levels.
