The UK Health Security Agency (UKHSA) has issued a yellow cold health alert for south-west England from 6pm on Christmas Day until noon on 27 December, warning of an increased risk to vulnerable people. The agency said low temperatures are likely to have a minor impact on health and social care services, including greater use of healthcare by those most at risk.
Despite the cold, a white Christmas is considered “highly unlikely” by forecasters. Oli Claydon, a Met Office spokesperson, said Christmas Day would bring “pretty decent” conditions with mainly dry weather across much of the UK. Southern England and Wales can expect a bright start, while northern areas will see cloud clearing by lunchtime, giving way to sunny spells.
Strong easterly winds, particularly along the south coast, may make it feel colder. High pressure is dominating the weather, bringing settled but cooler temperatures. The highest temperatures are forecast to be around 7°C in north-east England and 6°C in the south-east, while rural parts of Scotland could drop to -6°C overnight into Boxing Day.
Travel disruptions are expected as the RAC predicts 4.2 million festive getaway trips by car on Christmas Eve, with peak traffic between 1pm and 7pm. Drivers are advised to avoid busy periods, especially on the M25 and M5. Regular commuter traffic is likely to be lighter, but jams may form on major routes.
