So It looks like Friday up in NH there will be a swell from the SE and a swell from the NE. Both and around 5ft at 10. I don't know if it's a bathymetry question or not, but what happens when two similar swells combine like that?
combined swells combined swells can do both YING and/or YANG. their ideal behavior would be the creation of the a-frame we so love.
