The Met Office has issued a fog warning for major beaches in England, including London, as motorists are warned to be careful on the roads.
The yellow fog warning was issued across eastern, southeastern and southwestern parts of the country overnight.
The Met Office has advised motorists to be extra careful as the fog can lead to difficult driving conditions and some travel disruptions.
Warnings were put in place from 6 p.m. 4 and will run until kl. 10, which includes the East Midlands, Northamptonshire, East of England, London, South East England and South West England.
People are advised to be aware of slower travel times with delays to bus and train services.
There is also the possibility of delays or cancellations of flights.
Meanwhile, the British will see a rainstorm that was first heavy across Scotland and Northern Ireland, slowly edging southeast.
As the rain reaches northern England and Wales, it gets lighter and lighter. Elsewhere, morning fog spots will clear up later in the day to leave a nice, warm afternoon.
The British should get the most out of the disproportionately hot October weather – the long-term forecast calls for things to get colder and snow to fall over higher terrain in the UK as the month moves into November.
Snow could hit parts of the UK during the half-year holiday in October, with temperatures expected to plummet in the coming weeks.
Northern England, the highlands and Scottish borders could be covered in snow, according to The Sun.
Towards the end of the month, conditions will quickly become very turbulent across the UK as the Atlantic weather front moves in.
Brian Gaze, director and predictor of The Weather Outlook, said: “High pressure is currently bringing dry and mild or even quite warm conditions to large parts of the UK, although Atlantic weather fronts are keeping it more turbulent in the northwest.
“Towards the end of the month, some computer models indicate that high pressure will be centered north or west of the UK.
“If that happens, there is an increasing likelihood of colder weather leading to a risk of frost at night becoming quite widespread.”
