Thank you so much for the information. The Table for estimating wave size is very useful. If I were a geography teacher I would make a lot of use out of this table. As a person born to a a small village nearby the sea, I am quite familiar  with the wind , sea, and waves and always enjoy reading about them. Unfortunately, I am not in the capacity to do anything to prevent havoc that is likely tho occur someday in the future. Hopefully our government will  seriously think about the climate change and  invest to save our land.
