Meteorologists have blamed the polar vortex for the unseasonal weather.
The vortex is a circulating mass of cold air that primarily sits over the Arctic Circle.
Extreme 155mph winds pin it in place over the region, but a warming stratosphere is slowing it down.
Seasoned forecaster John Hammond told the Sun the increasing temperatures are preventing the expected late October intensification.
The “unusual weakening” could impact British weather from mid-autumn to early winter, with chances of a severe cold increasing.
But the consensus isn’t shared by bookmakers, who have taken the balmy start to October as a sign.
Betting firm Coral has slashed the odds for a “record hot” October this year.
They currently supply 2-1 odds that the month will end with higher than average temperatures, not a gathering chill.
