1984 versus previous years 



83. Mean midsurf position currents were consistent with prior years 

 with the exception of February and September (Figures 27-29) . The pier end 

 currents were consistently southward as during prior years. Anomalous south- 

 erly winds and mild southerly waves during February were responsible for the 

 spring type currents during the month. Persistent northerly winds and waves 

 during March resulted in the high means for the month. Likewise, persistent 

 northerly winds and waves caused the current reversal during September. 



All years combined 



84. All locations show consistent temporal variations and distinct spa- 

 tial differences in both magnitude and direction (Figure 30). Near zero an- 

 nual means (Table 8) for both locations within the surf zone reflect the sea- 

 sonal variations and frequent reversals caused by the varying wind and wave 

 conditions at the FRF. These contrast with the consistently southward monthly 

 mean currents at the pier end.
