TRANSACTIONS OF THE 



Climate of San Luis Obispo County. 



By Signal Service Observer, Me. J. E. Lewis. 



With persons who are thinking of emigrating to any particular section, 

 the question of climate is always one of prime consideration. If a man 

 lives in a malarial section, or one subject to the ravages of fever or con- 

 sumption, it is a duty which he owes to himself and family to remove, 

 provided he possesses the means, to a place where these baneful conditions 

 do not exist. Many portions of the Eastern States are cursed with just 

 such disease-producing climatic conditions. San Luis Obispo County, on 

 the contrary, is free from any of the causes that produce the unfavorable 

 conditions in many of the Eastern States. It is well known that a wide 

 difference in temperature exists in corresponding latitudes on the Atlantic 

 coasts of the United States and of Europe, and the cause has been well 

 established. While along the eastern shores of our own country courses 

 the Arctic Ocean current, bearing down from the Northern Sea its icy 

 waters, the western countries of Europe are warmed by the mighty Gulf 

 stream, which bears to their shores the thermal waters of the tropical 

 ocean. Equally fortunate with the western shore of Europe, California 

 along its whole length of nearly eight hundred miles luxuriates in the 

 balmy breezes of the great Japan current — that mighty stream of warm 

 water, which perennially washes directly against the western shores of 

 America. The temperature of the winds blowing over it is of course 

 affected by its heat, and they carry modifying influences inland, and as a 

 consequence during the greater portion of the year, San Luis Obispo 

 County enjoys the balmy healthfulness of the breezes, that blowing fresh 

 from the broad bosom of the Pacific, are moderated and softened by its
