Here are the tables of the 8 a.m. and 8 p.m. observations : — 
East Wind. 
Jan. Feb. Mar. April. May. June. July. Aug. Sept. Oct. Nov. Dec. Total. 
A.M. 38 22 27 21 16 9 14 19 22 28 31 27 274 
P.M. 21 17 17 30 22 16 18 19 18 24 17 10 229 
West Wind. 
Jan. Feb. Mar. April. May. June. July. Aug. Sept. Oct. Nov. Dec. Total. 
A.M. 49 44 39 34 18 20 18 20 34 38 41 60 415 
P.M. 51 47 55 48 42 54 49 58 62 55 50 72 643 
The fact brought out is that neither the west nor the east wind can be 
said to be in any way influenced by land and sea breeze conditions as 
compared with one another. There is, however, a decided tendency for 
the east wind to blow more as an evening one during the winter months, 
from April to August ; but otherwise these are purely normal in their 
directions, and blow quite contrary to the land and sea breezes. 
We can now tabulate the foregoing facts as follows : — 
Number of times the W. and NW. winds went to the SW. 
of an evening 65 
Number of times the SW. and W. winds went to the NW. 
of a morning 99 
Number of times the SW. continued 17 
Number of times the NW. continued 22 
203 
Total number of SW. night winds 146 
Total number of NW. morning winds 146 
292 
So that true displacing land and sea breezes blew upon 203 occasions 
out of 292. 
Number of times E. and NE. winds went to the SE. of an 
evening 97 
Number of times the SE. and E. winds went to the NE. of 
a morning 54 
Number of times the SE. continued 24 
Number of times the NE. continued 31 
206 
Total number of SE. night winds 171 
Total number of NE. morning winds 209 
380
