It depends on the depth. On deep oceans it can hit 500 mph. Near the land it slows down to 20 or 30 mph.

It is important to note that the 500 mph is simply a theory, there is no method to truly measure the speed of the wave. Also, if you follow the above link it explains that when the tsunami approaches any land it slows to 20-30 mph. This would even further refute the 500 mph.

∙ 14y agoTidal currents can move at speeds ranging from a few centimeters per second to several meters per second, depending on the location and the size of the tide. In some areas, like tidal straits or narrow channels, tidal currents can reach speeds of over 10 knots (about 5 meters per second).

Thanks to Glenn Elert's online Physics Fact Book:
"The maximim for the Gulf Stream is 2.5 meters per second on the surface and 0.02-0.10 meters per second in deep water."

∙ 10y agoIn deep ocean water, a tsunami can move at about 500 mph. When they get into shallow water they slow to 50 mph ot less.
The speed of a high tide can vary depending on factors such as the geography of the area, the moon's phase, and the strength of the tidal currents. In some cases, high tides can move at several miles per hour.
Tidal currents
Tidal outflows are called ebb currents. Ebb currents occur when water flows away from the shore as the tide goes out.
Tidal currents are strongest during the peak of high and low tides when the water level difference between two areas is greatest. This typically occurs around the times of high and low tide, when the gravitational forces of the moon and sun align.
The three types of ocean currents are surface currents, deep currents, and tidal currents. Surface currents are driven by winds, deep currents are driven by density and temperature differences, and tidal currents are driven by the gravitational pull of the moon and sun.
The speed of a high tide can vary depending on factors such as the geography of the area, the moon's phase, and the strength of the tidal currents. In some cases, high tides can move at several miles per hour.
M.J Howarth has written: 'Intercomparison of current meters in fast tidal currents'
Tidal currents are not quite the same thing as tides. Tidal currents are horizontal movements of water caused by the tides.
No, tidal bulges are caused by the gravitational pull of the moon and the sun on the Earth's oceans, resulting in a slight distortion of the water's surface. Turbidity currents are fast-moving underwater sediment flows that are driven by gravity, occurring independently of tidal forces.
Longshore currents, rip currents, tidal currents, and wave action are some of the main currents that can move sand from one place to another along coastlines. These currents can transport sand along the shore or offshore, influencing beach erosion and sediment deposition in different areas.
