WAVES 



The barrier reef provides an effective breakwater for waves generated 

 in and outside of the Tongue of the Ocean. Consequently, much of the 

 shoreline on Andros is protected. A wave height of one foot inside 

 the windward lagoon is rare. Along the eastern shore of Golding Cay 

 and High Point Cay, where there is a sheer rock wall over 15 feet 

 high, waves may, however, exceed the one foot height. There is 

 no barrier reef to protect either island. Consequently, the sea- 

 ward side of the island receives the full force of all westerly 

 waves . 



In the Tongue of the Ocean, theoretical wave heights of 11.3 feet 

 can be generated at a wind speed of 26 knots. DeLeonibus (1960) 

 presented Figure 4 which represents observed seasonal wave heights, 

 direction, and frequency in the Tongue of the Ocean. From the same 

 report ( Ibid.) Table 3 summarizes the most probable wave heights 

 from all directions for wind speeds ranging from 10 to 26 knots 

 under unlimited duration at the downwind edge of the fetch.
