There is an almost never-ending grey lid of cloud over the area and the sun shines far less often than on the Lancashire plain. In this respect climate has affected farming. It means that there is too little sun to ripen crops even if the soil was suitable.
Rainfall also plays a large part in the life of the farmers. Here rainfall is above average, being affected by its proximity to low-pressure systems responsible for wet and stormy weather as the climate is. The low-pressure systems produce systems produce rain without any assistance from topography, but the fells cause a higher rainfall on the west-facing slope. The Darwen – Calder gap in which Rishton is situation is a dry cauldron that averages 40 – 42 per year. The heavy rainfall, together with the boulder clay means that fields are often flooded and some fields are nearly always marshy so making the land unsuitable for arable farming. This heavy rainfall does however mean that grass grows well.
The following table shows the heaviness of Rishton’s rainfall since 1948, compared with an area such as the Cheshire plain where farming takes place, which has an average yearly rainfall of 30 inches.

This table shows that rainfall in Rishton is heavy and frequent with over 50% of the days of the year experiencing rain.
The table below shows the frequency of which months are driest and wettest within a given span of years.
Wettest and Driest months
Both these tables show the inconsistently of Rishton’s weather. This is very bad for farming. From the above table it can be seen that August is the wettest month and December next. There is an autumn maximum. Spring is the driest season with March being the driest month. This is unfortunately because the farmers depend on their hay for food for the cattle during the winter. If there is little rain, then the grass is of a poor quality. Harvesting is usually done May, June and July – This again is unfortunate because at this time of the year the weather is unreliable as can be seen from table 2. Even though June is dryer than May and July, because of the large numbers of days of rain in a year (table 1) the weather is still not dependable. At least a week of rain free days are necessary to ensure that the farmer can get the grass cut, dried, baled and stored to ensure adequate supplies of hay for the winter. Large supplies of hay are needed because of low autumn and winter temperatures that means that the cattle have to be kept indoors for a long time.
December 2010 saw the driest December on record, with just 1.3 inches of rain falling. It was also the coldest December on record with temperatures in Rishton reaching -17c. This extreme weather lasted for the entire duration of the month.
