fVinds and Weather on the Western and Northern Coasts of 

 Australia. 



By Commander J, C. Wickham, R.N. 



The winds on the western coast of Australia, are, for the 

 most part, from some southern point— chiefly between S. S. W. 

 and S. S. E. 



During the summer, or from the early part of October to 

 the beginning of April, they are almost constant from this 

 quarter ; but in the winter their regularity is broken in upon 

 by occasional winds between north and west that at times 

 blow with great violence, and are accompanied by heavy rain, 

 and thick dirty weather. 



Near the shore, land and sea breezes appear to be regular ; 

 the former generally dying away towards the middle of the 

 day, after having reached as far as E. from about S. E. at 

 sunrise ; then follows a short interval of calm, after which, the 

 sea breeze sets in, mostly at S. S. W., and draws to the east- 

 ward of south in the evening. 



At times the land wind veers round the compass, and is 

 then generally stronger than usual j blowing fresh for a short 

 time from N. E., and bringing a parching heat from the land ; 

 upon these occasions the sea breeze comes in from a more 

 western point, and is lighter. 



At Swan River, in the months of December, January, and 

 February, the sea breezes are very strong, for intervals of from 

 three to five days ; during which time they blow fresh through- 

 out the night — drawing to the southward after midnight, and 

 towards sunrise to S. S. E. and S. E., but more moderate. 

 In the middle of the day, they back again to the southward,
