Halloween 2018 weather

Could it turn cold?



Late October often brings unsettled weather but fine and settled spells are also perfectly possible. Halloween 2014 was the warmest on record in the UK. Gravesend, Kent and Kew Gardens, Greater London both recorded temperatures of 23.6C (74.3F) on 31st October and in much of the south temperatures exceeded 20C (68F).

This year's Halloween weather

Ensemble computer models suggest the possibility of the weather turning more changeable in the run up to Halloween. Nonetheless a significant number of the individual runs show high pressure continuing to keep a more settled pattern in place. There is also a signal for it to turn cooler or colder and if that happens, the winter woollies could be making an early appearance this year.

The postage stamp chart below shows forecast rainfall at 18:00GMT on Halloween. Despite the likelihood of it becoming more changeable, quite a few of the runs show dry conditions. Based on this data, rain is most likely in the north and in coastal districts, the latter suggesting the possibility of it being showery.

It is too early to be confident about the Halloween 2018 weather prospects. At the moment ensemble computer models are hinting at more mixed weather developing later this month. Despite that there is a reasonably good chance of dry conditions prevailing in much of the country. It may also turn colder and if that were to happen snow would be a possibility over high ground in the north.
