How fast do ocean waves travel?

I would think that swell speed would play a big role in influencing the size and power of breaking waves. A wave that is moving at 15 mph would contain a lot more volume than a wave that is moving at 10 mph even if they have the same period, right? Or do open ocean swells all travel at approximately the same speed? read more

So, for a surface gravity wave of length 10m, the packet would travel at approximately 1.97 m/s, or 4.4 mph. Assuming a Pacific Ocean 5000 miles in width, it would take 1136.36 hours, or 47.34 days for a deep water wave to traverse the Pacific basin. read more

The speed of travel of the deep water swell group will be 1.5 times the swell period; ie: a 20 second swell will be traveling at 30 Nautical mph. The actual individual waves will be traveling at three times the swell period, so a 20 second swell will have waves moving at up to 60 Nautical mph. read more
