Of course really we need the statistics.
I wrote on my site
"Snow in October was more common in the last century; indeed, there is some evidence that Octobers have been warming up considerably (more so than average), although most of the warming is due to a run of very warm Octobers between 1957 and 1972, and more broadly from 1940. The October of 1974 was then very cold. Until recently, October (along with June and December) has shown no warming trend since the 80s - but then three of the warmest have been in the last 11 years."
Although I am not altogether sure when I wrote that - it could be around 2000!
