That’s right. First October snowfall in London in 70 years.
Snow settled on the ground in parts of the capital last night as temperatures dipped below zero. A Met Office spokeswoman said it was London’s first October snow since 1934.
For greater south-east of England it was the first October snow since 1974. High Wycombe in Buckinghamshire had 3cm (1.2 inches). One of the coldest temperatures recorded was -4.1C in Benson, Oxfordshire.
“It is unusual to have snow this early,” the Met spokeswoman said. [link to source]
