Grand Harbour , Grand Manan 



The monthly means tabulated here suggest 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 during; the period 1929-1936 (Hachey, 1939). The annual 

 mean temperatures are almost the same for both olaces. 



Tenoerature fluctuations at Grand Harbour are subject to day 

 to day variations of several der^rees due to the broad expanse of shallow 

 water where extreme heating or cooling may take place, the lar--e tidal 

 ran^e and broad ooening to the South 'and liioroughfare to the northeast 

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

 tide.
