It's been a mild autumn so far with very little, if any, frost to speak of. Temperatures today are once again above average across the country ranging from 15-18°C and won't drop much tonight.
Tomorrow will be even warmer, typically 17-20°C but on the north coast 21 or possibly 22°C is possible in places. This would make it the warmest Halloween on record!

The reason for the unseasonably high temperatures is the wind direction. The wind tomorrow will be from the south bringing warm air to us all the way from Spain and Portugal.
On the north Wales coast the temperature will be boosted by the Foehn effect whereby warm moist air blowing across the mountains dries out and warms as it descends on the other side. In North America this wind is called the Chinook.
Over the weekend, it will turn cooler with temperatures dropping by a few degrees. It will be breezy with some dry weather and sunshine on Saturday but there is some rain on the way as well. The worst of the wet and windy weather is expected on Saturday evening and overnight, followed by brighter weather and scattered showers on Sunday.
The highest temperature recorded in November is 21.7°C in Prestatyn in 1946, 12-15°C is more likely over the weekend. While next week it looks like it will be turning colder with temperatures dropping below average and chilly on Bonfire Night.
