The Met Office has revealed why New Year's Eve is set to be the hottest on record.
The forecasting agency is expecting an unseasonably mild end to the year with temperatures as high as 15C .
This could surpass the previous high of 14.8C set in Colwyn Bay on December 31, 2011 - as Mirror Online reports.

The warm conditions are due to warm air from the Azores and the central Atlantic billowing into the UK.
Craig Snell, forecaster with the Met Office, explained the milder temperatures were "all to do with the wind direction".
He said: "Earlier in the month we had some cold northerly winds, but from today the winds are coming in from the South West, you can trace the air back to the Azores and the central Atlantic.
"It's still pretty warm there at this time of year, so we are tapping into the milder air that's being dragged up to the UK.
"It means it's very mild for the time of year, particularly in the South West of the UK."
"We are keeping a close eye on the New Year's Eve weather, because that record (14.8C) is quite under threat.
"But it looks like the transition (to cooler weather) will be on Bank Holiday morning.
"We will see the winds switch around so temperatures will return down to normal, with a smidgen below normal in the north of the UK."
The mild temperatures are expected to last until the end of the week, before temperatures are expected to drop in the New Year.
Mr Snell added: "After New Year's Eve there is a trend for temperatures to return nearer to normal.
"That's not surprising as temperatures are way above average."
