I clearly remember April 1981.
I was at a mates house drinking beer and chewing the breeze until the small hours. The lights were flickering in the house and my mate said that there must be snow. Being April we laughed it off. Until I left the house at about 4am, and the snow had drifted up above the foot of the back door. I only had to walk home about 1/2 mile, and by the time I got in my beard was full of ice, from condensed breath.
I lived in an old Victorian house, with all the waste pipes on the outside wall. Oh! how they froze solid. We couldn't use the sinks for a week.
