Thursday 08/23/2012 Report and Prediction

Report:  Much of the same as yesterday; small-scale mid-period background swell with occasional pulses of longer period waves.  Light offshore winds early, with winds shifting and increasing from the SE as the day heats up.

Prediction: A similar pattern through the end of the work week; smaller mid-period background swell with longer period pulses from the Low-High interaction of TS Isaac and perhaps a little of TS Joyce in there as well.  Again, I expect wave heights to increase a bit over the next  few days as Isaac closes the distance on his Westward path and as Joyce develops and moves Northwestward as well.  Winds are predicted to be light-to-moderate and variable in direction over the next few days, providing periodic opportunities to take advantage of whatever swell finds its way to our shores.

Extended Forecast:  Continued building mid-period/long-period combo swell for the weekend, but with potentially troublesome onshore winds.  As always, I recommend you monitor sources of local weather info for up to date wind and swell conditions.

Tropical Outlook: Isaac’s track has shifted southward once again, looking like he will now be turning towards Puerto Rico and  FL and likely side-slip laterally into the far-Eastern Gulf of Mexico.  So Isaac will likely not be an significant/optimal swell-generator in the near future (but it is still TBD whether or not his remnants will eject off the Carolinas or just run up the eastern seaboard and influence things next week).  The better news is Tropical Storm Joyce, who appears to be setting up for a more favorable path through our swell window.  I will monitor the situation and update accordingly; until then, I’ve linked to’s projected path for Joyce as a teaser:
