1 Hp T„, &„ represent CDIP 77 array gage outside Kahului Harbor; 





H^, T„, B m represent NDBC buoy 51026. 





In conclusion, the time period of available measurements at the array gage 

 appears to give a good representation of the overall wind wave and swell climate 

 immediately incident to Kahului Harbor. It is recommended that the array data 

 be used as the primary source of wave information for driving numerical and 

 physical models of the harbor.
