CLIMATE is in winter and spring ; autumn and winter, however, have a greater number of wet days than spring and summer. January is on the average the coldest month, and July the warmest. Assuming that the mean temperature of each month occurs about the middle of the month, it would appear that the increase of temperature is most rapid during the month of May, and that the decrease is most rapid during September and October. In two months only, July and August, has the temperature never been below freezing-point (32), and in two months only, December and January, has it never exceeded 62. Tables V., VI., and VII. give particulars of the rainfall for the longest available period under each heading. A day of rain is one on which at least o - oi in. of rain falls, any fall of 0-005 "* to ' OO 9 i n - being considered as o'oi in.
