Tides and currents
Tide is the rise and fall of sea levels due to gravitational forces of the sun and the moon. Due to Earth's rotation, high and low tide are usually 6 hours 25 minutes apart.
An ocean current is a steady flow of seawater generated by winds, temperature gradients and other physical phenomena. Ocean currents affect climate both in the sea and inland. Some currents are seasonal.
UnderstandTides are only noticeable in sea water. Although freshwater lakes are subject to the same gravitational forces, the water cannot move a great enough distance for you to see a tide.
DestinationsAtlantic Canada and Britain and Ireland have locations of extreme tidal range.
