As far as long period swells, the longer the period the the deeper the water the wave energy reaches down. So, many places along the east coast have a hard time dealing with the long period swell, because some of the energy can be absorbed offshore and also the sandbars generally cant handle the long period swells.
Your remark about high tide is generally a good one with the longer period swells. The higher water level means less chance for the wave energy to be absorbed offshore.

long period swells coming
Models are calling up to 16 sec period waves for wednesday. I thought we only saw those kinds of periods from southern hemi swells or hurricanes. Looks like the waves are coming from a low that is going to build in the north atlantic over the next few days, but we see normally SW-SE wind swell from these lows. What gives? Swellinfo, im thinking you can give a good explination. Also how bad will the continental shelf hurt a swell at this long of a period?
I'm thinking high tide by an inlet is the way to go on this one.
