Eine Bauernregel sagt:
Hängt das Laub bis November hinein, wird der Winter lange sein.
Das klingt nach einem strengen Winter.
A country lore says:
“If in the fall of the leaf in October many leaves wither on the boughs and hang there, it betokens a frosty winter and much snow”
The German version says "if there are still leaves in November, winter will be a long one".
And there are still many leaves!
