First I gotta say, the image you see is the animated period (when we say “seconds”) of the swell and not the swell chart. By this thing being all green like that, it is saying that a massive body of water in a couple thousand miles across is creating that. I have never seen all green like that. It’s like it is creating the perfect swell. It looks to be a 14 plus period swell, but unlike the 17 second period of Hurricane Bill, this swell we have coming is solid green across meaning it is way bigger than a hurricane in regards to the fetch of the weather body. (“fetch” is the distance traveled over water that winds are created from the storm)
Right now its showing double overhead as a minimum, we’ll se.
