CLIMATOLOGICAL OBSERVATIONS TAKEN IN HERTFORDSHIRE 



IN THE YEAR 1893. 



By John Hopkinson, F.L.S., F.G.S., F.B.Met.Soc. 



Read at Watford, 17 th April, 1894. 



Observatioxs continue to be made at the five stations for which 

 the six pre^-ious annual reports have been di'awn up, and therefore 

 I give for the year 1893 the usual series of tables. 



The mean temperature of Hertfordshire in 1893, deduced from 

 these observations, was 2°-6 above that of the six previous years, 

 and l°-2 above the mean of 1882-86. The year was therefore 

 decidedlv warm. The mean daily range was verv great, being 

 2°-7 greater than in 1887-91, and 2°-\ greater than in 1882-86. 

 The extreme range was greater than in any previous year. The 

 air was much less humid than the average of the six previous 

 years, the amoiint of cloud was rather less, and the rainfall was 

 considerably less, and on a much smaller number of days. The 

 weather was very warm in spring and summer, excessively dry 

 in spring and the early part of summer, but cold and rather wet 

 in autumn. 



All the observations are made at 9 a.m., the maximum tempera- 

 ture and rainfall being entered to the previous day.
