Kyle, most web forecasters don't account for specific swell directions for each break all that well... it's a lot of data to crunch. Pay attention to swell direction and find the beaches that are best depending on that factor.
I know Florida has a slowly sloping shelf, does this take all the thunder out of this ground swell?
Generally yeah...long period swell gets more frictional drag coming across the shelf than shorter period wind swell. But the part of Florida your talking about....Broward, Palm Beach, Martin..etc. I thought had some of the smallest continental shelf in the east coast. Maybe ENE swell direction gets shadowed by Grand Bahama bank a bit? That bank extends pretty far north.
