from the northeast, however, in the wake o£ the 9 to 12 February 1973 

 northeaster, when 10- foot breakers were reported approaching at an angle 

 of 10° to the north of a normal approach. Breakers from the northeast 

 were predominant during October through March. 



At Hollywood, the higher breakers were generally from the southeast 

 and prevailed during January, March, May through July, and September. 

 The highest breakers (5 feet) were observed coming directly onshore (two 

 observations) . Breakers from the northeast predominated during February, 

 April, August, and October through December. 



Figure 29 is a plot of the monthly averages of breaker height and 

 period from the three sites. Both parameters decreased from north to 

 south, which may have been the result of attenuation of waves by the 

 Bahama Banks. Average breaker heights at Jupiter, Boca Raton, and Holly- 

 wood, from north to south were 2.8, 2.0, and 1.6 feet (0.8, 0.61, and
