I have been waiting for the November rainfall stats for Sheffield, which was at the heart of the heaviest rainfall leading to the S Yorks floods.

It was the wettest November on record there since measurements began in 1883, and it was also the wettest autumn. As we know, for the country as a whole this was nowhere near being the case.

However across all months of the year, last month was not particularly exceptional, ranking the 6th wettest month in Sheffield with 200mm.

June 2007 obviously stands out as one-off outlier, but wetter months were also seen in 1973, 1977, 1978 and 1982.

Perhaps the most comparable month from a seasonal point of view, which was December 1978, which saw 207.9mm.

Although this year set the November record, it was almost as wet in November 1951, when 199.2mm fell.

Whilst this autumn was the wettest in Sheffield, there have been wetter 3-month periods in the past.

Given the amount of rainfall seem in June that year, it is little surprise that May to July 2007 tops the list.

But Nov 1929 to Jan 1930 also exceeded this autumn’s total, 459.9mm v 453.7mm.
