Grand Harboiir , Grand Man an 



The monthly means tabulated here sug-est that the temperatures 

 in Grand Harbour are lower during the winter months and higher during the 

 summer months than those recorded at Southwest Head, Grand ^Manan, almost 

 eight miles away durin- the period 1929-1936 (Hachey, 1939). The annual 

 mean temperatures are almost the same for both olaces. 



Temoerature fluctuations at Grand Harbour are subject to day 

 to day variations of several dep;rees due to the broad expanse of shallow 

 water where extr°me heating or cooling may take place, the large tidal 

 range and broad opening to the South -and thoroughfare to the northeast 

 permit substantial exchange with the open sea dependent on the wind and 

 tide.
