Tomorrow will be the warmest Halloween on record, continuing a "remarkable year" of high temperatures, weather experts have said.
The mercury could hit an unseasonably warm 19C in Runcorn and Widnes, seven degrees higher than is normal for this time of year.
So far, 2014 is the warmest year on record, following consistently mild temperatures which have continued into autumn.
Forecaster Laura Caldwell said: "Tomorrow is expected to break the record to date for the last day of October.
"Right across England and Wales it will be warm and it's been fairly warm for an October in general.
"The whole year to date has been the warmest on record so far. It's been a remarkable year for above-average temperatures."
Temperatures this week have hovered just below 20C at their peak in central England.
Next week the weather will begin to cool and temperatures will return to the average of around 10 or 11C for November.
