A CO Down weather station has recorded the warmest November night in the north or Britain.
Murlough recorded a top temperature of 16.1C - the warmest since records began.
The weather across Britain and Ireland has been unseasonably warm over the last few days.
Waddington in Lincolnshire recorded a high of 14.8C, breaking the previous record of 14.4C, which had stood since 1969.
And in Leconfield, Humberside, an 11-year record was broken with a temperature of 15.1C.
A Met Office spokesman said: "Last night was the warmest November night on record and quite a few records were broken.
"We have had very mild south-westerly air flowing over the UK which is drawn up from over the tropics.
"On the other side of the Atlantic the jet stream is turning southwards and so what goes down most come up as warm air is being pushed north.
"We have had a few weeks now where we have enjoyed winds coming from that direction."
The conditions are expected to change though after Storm Abigail, the first storm to be named by the Met Office, hits northern Scotland later this week with winds expected to be up to 80mph.
