The Atlantic coast of the United States experiences semidiurnal tides with two high tides and two low tides each day. Tidal ranges vary dramatically from north to south.
Regional Variations
Maine and Maritime Canada
The Bay of Fundy between Maine and Nova Scotia has the highest tides in the world, with ranges exceeding 50 feet during spring tides. Maine coast typically sees 8-12 foot tidal ranges.
Mid-Atlantic
From Massachusetts to Virginia, tidal ranges average 4-6 feet. Chesapeake Bay and Delaware Bay have complex tidal patterns influenced by their large size and multiple inlets.
Southeast Coast
The Carolinas and Georgia experience 6-8 foot tidal ranges. The extensive salt marshes and barrier islands create intricate tidal creek systems.
Florida East Coast
Florida Atlantic coast has smaller tidal ranges of 3-5 feet. The Gulf Stream offshore influences tidal patterns and creates strong currents near inlets.
Seasonal Patterns
East Coast tides show seasonal variations with higher tides in fall and winter due to storm surge and seasonal wind patterns. Hurricane season brings extreme tidal flooding when storms coincide with high tides.
Impact on Activities
The significant tidal ranges along the East Coast affect boating, fishing, and coastal access. Many harbors and marinas are only accessible during high tide, and fishing is best during strong tidal currents.
Conclusion
East Coast tides vary dramatically from the extreme ranges of Maine to the moderate tides of Florida. Understanding regional patterns helps you plan coastal activities and stay safe in tidal waters.
