I've heard that on the east coast the continental shelf extends far out to sea and that is the reason why our waves lack power. I want to know why does the surf forecast report swell height let's say head high on monday for thursday then come thursday it may drop down to waist high. Is it the continetal shelf thats responsible or is it that the low pressure systems weaken..or is it that the bouy is screwy?
Food for thought. You do the dishes!
