What are tide variations in Maine?
Maine’s coastline varies dramatically in terms of tidal fluctuations. Tides in Maine are semi-diurnal, meaning there are 2 highs and 2 lows in a 24-hour period. Tides range from 5.6 meters (18.4 feet) in Eastport to 2.6 meters (8.7 feet) in Kittery. The tidal range increases with the new and full moon phases to create spring tides that are 10 to 15% larger than the mean range. Online tidal forecasts and historical records for Maine are available from the National Ocean Service.
