In the early hours of last Friday morning, just before I was off to bed, I noticed our cheap-and-cheerful 4-channel digital thermometer was reading -12.2 degrees C from the outdoor sensor.
It's hardly a precision instrument, more of an ornament than anything else, but its greenhouse sensor was also reading below -10 degrees and so it was worthy of further investigation. I dug out a torch and went outside to the bottom of the garden, where I've a 'proper' mercury max-min thermometer mounted on the shed wall.
Sure enough, it was cold, -10 degrees at that time and when I checked again during the day it had been down to -11 degrees C, a record low in the ten years since we've lived here, and by quite some margin.
