The heaviest snowfall in modern London was in February 1991. The city was buried. Cars vanished. It was basically a winter apocalypse.
People built igloos in Hyde Park. Seriously. You couldn’t move for snowmen.
It happens so rarely that we over-celebrate when it arrives. That’s the charm. We don’t know how to handle it, so we just enjoy the ride.
The Final, Unscientific Rule
If you want to know when it’s going to snow, ignore the TV. Look at the parking situation in your street.
If you see your neighbours moving their cars onto the pavement “just in case,” snow is coming. It’s the unofficial London barometer.
Or, just watch the traffic cams for Heathrow. If planes are grounded, you’ll have your answer. Grab a hot chocolate and watch the city go bonkers.
