How tall can waves get in the middle of the ocean?

Waves in the oceans can travel thousands of kilometres before reaching land. Wind waves on Earth range in size from small ripples, to waves over 30 m (100 ft) high, being limited by wind speed, duration, fetch, and water depth.

Has anyone tried surfing a tsunami?

Has anyone ever tried to surf a tsunami? There are a few surfers who have been out in the water when a tsunami hit. Big wave surfers chase waves created by storms all around the world, but they do not surf tsunamis. This is a bit disingenuous as the surfers aren't actually surfing the tsunami itself. Also, what would happen if two tsunamis collide? The waves would continue on their paths with some amount of addition or subtraction. Sometimes large incoming shore waves will produce a significant backwash wave. Where the water is shallow the backwash wave adds to another incoming wave to produce a bigger wave but in deeper water they simply pass through each other.

Accordingly, how often do tidal waves happen?

Because the Earth rotates through two tidal "bulges" every lunar day, coastal areas experience two high and two low tides every 24 hours and 50 minutes. High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high. Consequently, why does tide go out before a tsunami?

How tall can a tidal wave get?

In other places tsunamis have been known to surge vertically as high as 100 feet (30 meters). Most tsunamis cause the sea to rise no more than 10 feet (3 meters). The Indian Ocean tsunami caused waves as high as 30 feet (9 meters) in some places, according to news reports. Regarding this, what is the biggest tidal wave ever recorded? Lituya Bay, Alaska. Its over 1,700-foot wave was the largest ever recorded for a tsunami. It inundated five square miles of land and cleared hundreds of thousands of trees.
