The Pamphlet Collection of Sir Robert Stout: Volume 62



Having dealt with temperature and rainfall in my lecture on the North Island separately, I will now refer to these two items as affecting this island as shown by observations made at Lincoln on the Canterbury Plains and Dunedin in Otago, taking the figures as to the former for the year 1890. Bear in mind the observations are made daily at 9.30 a.m. At Lincoln the mean temperature in the shade for the whole year was 52.2deg. Fahr., while at Dunedin it was 51.1deg. The maximum and page 27 minimum were respectively 94.8deg.—84deg. and 26.4 deg. and 31deg., showing an extreme range of 68.4deg. and 53deg., the maximum being only reached on one day in the year. Comparing the two islands it will be found that the mean average temperature of the south is 52.1deg. against 56.7deg. in the north, being thus 4.6deg. cooler. The rainfall average for three years ending 1890 showed 27.3m. per annum, and rain fell only on 130 clays in each year, leaving 235 days absolutely fine.
