In the Babbage Report of 1850 written by Benjamin Herschel Babbage (see blog post below) there are some references to the meteorology of Haworth:
"Meteorology: No register of the direction of the wind is kept at or near Haworth, but judging from the general prevalence of south-westerly winds in this part of the country, the prevailing winds at Haworth would probably be found to come from that quarter.
Mr Shackleton of Braithwaite, near Keighley, which is about four miles from Haworth, was kind enough to furnish me with the following extract from his register of the rainfall:-
In 1840 31.16 inches
In 1841 36.21 inches
In 1842 28.02 inches
In 1843 35.90 inches
In 1844 21.17 inches
In 1845 31.23 inches
In 1846 32.44 inches
In 1847 32.27 inches
In 1848 40.38 inches
In 1849 31.66 inches
Average of the above ten years 32.7 inches"
One thing of note looking at the rainfall - how wet it was in 1848 (40.38 inches) which was the year that both Branwell and Emily died of consumption (tuberculosis).
