Tidal measurements initiated by NAVOCEANO (IMR 0-21-64) in 1963 

 have been reported and are continuing at Salvador Point and Fresh 

 Creek . 



DeLeonibus (1960) calculated theoretical wave heights under varying 

 conditions of wind and fetch in the Tongue of the Ocean. 



Meteorological data were provided by the Bahamas Meteorological 

 Service which maintains a permanent observation station at Mangrove 

 Cay, Andres Island, and other islands throughout the Bahamas. 



CLIMATOLOGY AND OCEANOGRAPHY 



Monthly air temperatures, humidity, rainfall, and wind speed over 

 a four year period at Mangrove Cay is presented in Table 1. Seasonal 

 and annual wind roses as measured from November through October 1963 

 are shown in Figure 3. No wind directions were available from 1957 

 to 1960. 



Winds approaching hurricane strength are most probable in the 

 months of August, September, and October when 79 percent of the 

 hurricanes occur. An average of two hurricanes invades the Bahamas 

 annually. 



TIDES 



Tidal corrections to be applied to tide predictions at Hampton 

 Roads, Virginia, from Fresh Creek, Salvador Point, and Pigeon Cay 

 are presented in Table 2. Tides in the Bahamas are semi-diurnal 

 with a diurnal inequality, and show a mean range of approximately 

 3 feet. Tidally induced currents in the lagoon are generally low 

 speed (<0.2 kts). In the Andros Bights (e.g., between Big Wood 

 and Gibson Cays) the current can reach 1 knot.
