Last winter was our coldest for 31 years, Londons coldest temperature last winter was -1.2C whilst further north parts of Wales hit -14.5C and Manchester hit -16.4C.
The car was reading -15C one morning in Berkshire..
Something for the cold, something for the rain that can also keep out cold wind. Simple things like beanies, scarves, gloves etc with a long coat if you're waiting at a station or something.
