From what I remember without looking anything up:
January - Pretty benign
February - Had that unseasonably hot spell which wa
March - Had that heavy snow event in Manchester which caused chaos during rush hour
April/May - Cool-ish, no early summer
June - Average, we've had worse in recent years.
July - Had the heatwave for a couple of days which was swiftly followed by the awful rains at the end of the month which carried on
August - Was this good or poor? Certainly wasn't hot and there was more torrential rain causing problems.
September - No Indian summer, rain eased off a bit at first but came back at end of the month
October/November - Didn't stop raining
December - Average, wet at first but no notable windstorms and improved towards the end
I think 2019 is notable for the lack of classic windstorms, instead replaced by low pressure systems coming from odd angles which just sat in one place causing terrible flooding.
