The UK is experiencing some rather strange weather at the moment.
Yesterday was the hottest November day ever recorded in Britain, with parts of the country having sunny weather.
But thick fog is also causing problems across the UK.
Dozens of flights have been cancelled or delayed at airports across the UK and Europe and there were lots of delays on roads because of the thick fog.

- Have you spotted the fog too?
