Yes
Yes, waves do speed up as they approach the shore because the energy of the wave is compressed into a smaller area. This causes the wavelength to decrease, leading to an increase in wave speed.
As a wave approaches the shore, its height increases and its speed decreases. This causes the wave's energy to be concentrated, leading to the wave breaking as it reaches shallow water near the shore. The breaking of the wave causes it to release its energy, creating the crashing sound associated with waves hitting the shore.
The wave speed decreases as it enters shallower water near the shore due to a decrease in water depth. This causes the waves to slow down and increase in height, ultimately leading to wave breaking as the top of the wave moves faster than the bottom.
As waves approach the shore, their height increases, and their speed decreases due to the interaction with the sea floor. The wave crests become steeper and eventually break as the waves approach the shallow water near the shore.
The wave would slow down as it approaches the shore.
To estimate the speed of a wave, a person can estimate the distance the wave is from shore and then time how long the wave takes to reach the shore. For example, if a wave is one mile out and it takes one minute to reach shore, the wave is traveling at 60 miles per hour.

Friction with the sea bed/shore
Waves slow down near the shore due to the decrease in water depth. As the waves approach shallower water, the wave energy is compressed, causing the wavelength to decrease and the wave height to increase. This change in wave characteristics ultimately leads to a decrease in wave speed.
because of the wave
The speed of a tsunami wave decreases as it approaches the shore due to the shallowing of the ocean floor, causing the wave to compress and slow down. However, the height of the wave may increase as the energy in the wave is concentrated, leading to higher waves onshore.
As a tsunami wave approaches the shore, its speed decreases due to the wave energy being compressed into a smaller space. This leads to an increase in wave height and impact force when the tsunami hits the coastline.
