On the same day that thick fog enveloped the country and grounded hundreds of flights and Heathrow, the UK experienced the hottest November day on record - with some parts of the UK experiencing higher temperatures than southern Portugal.
According to the Met Office, temperatures on Sunday 1 November in Trawsgoed, Wales, were the hottest ever recorded in the UK in November - the temperature peaked at 22.3C, hotter than Barcelona and the Algarve.
The previous November temperature record was set in 1946, when it got up to 21.7C in Prestatyn, Wales.
To put that in perspective, the average maximum temperature in the UK is 10 to 13C.
According to the Met Office, Sunday's new record could be broken again on Monday - meterorologist Nicola Willis said there was a 20 per cent chance that the record could be broken again at some point on 2 November, as southerly winds bring in warm air from Europe.
Despite the record-breaking temperatures, Sunday started off foggy for most the country, and stayed that way in some parts throughout the day.
British Airways cancelled at least 20 flights from Heathrow and more than a dozen arrivals at London City Airport due to fog on Sunday.
With more fog disruption expected on Monday, the UK could be in for a continued spell of bizarre weather.
