Although it was a warm start to the day, London was woken up by a sudden change in the weather as the heavens opened, soaking all those Londoners who left their coats at home.
Here are some of those who got caught out.
The weather prompted a modern sort of romance.
Some were simply just not dressed for the sudden change in the skies.
There was a lot of running.
And some went to extreme lengths to protect themselves.
Note to self: Always carry an umbrella with you in the UK.
