The winds most prevalent at Madras are, the easterly or Sea Breeze 

 which blows more or less for several hours during every* day through- 

 out the year — the westerly or land wind which sets in regularly on or 

 about the 16th May, (blowing from 10 p. m. to 11 or 12 a. m. when it is 

 relieved by the sea breeze) and continues till the middle of August — 

 the southerly or along shore wind, sets in about the beginning of March 

 and continues till the middle of May ; and lastly the north east or 

 monsoon, which sets in about the middle of October and continues till 

 the end of February. 



In conclusion we subjoin the following interesting extract : — 



"Gales of Wind and Storms. — Gales of wind at Madras usually occur 

 only during the rainy season, between the 15th October and the mid- 

 dle of December ; the barometer seldom sinks much more than four- 

 tenths of an inch, or stands lower than 29.45 inches. These gales be- 

 gin rather to the westward of north along the shore, veer to the west- 

 ward, and increase in violence as they get round ; this change of di- 

 rection continues, the wind gradually abating, until it is at south, when 

 it frequently falls almost calm. From what has been just stated, the 

 necessity for Ships in Madras roads getting under weigh immediately a 

 gale commences is apparent ; as when the wind has veered easterly, it 

 is next to impossible to get sea-room, and the vessels must be driven on 

 shore. 



* The sea breeze occasionally fails for 2 or 3 days in the month of June, when the heat 

 is very oppressive.
