The Met Office has said it will 'feel significantly colder' in some parts of the UK this week.
It comes as high temperatures were recorded over the last week, with highs of 22C in Liverpool and 25C in the South East.
But the weather will take a turn today, with the Met Office predicting this week to be the start of autumnal weather.

Nicky Maxey, for the Met Office, said: "There's still some sunshine scattered round on Monday but we could see heavier showers.
"Hail and thunder is also a risk to the North and West, so Monday heralds a real change towards the autumnal-style weather."
According to the Met Office, heavy rain and strong winds will clear quickly by mid-morning in the North West, leaving sunshine and blustery showers, some of these heavy.
Temperatures in Liverpool will peak at 16C, but it will only feel like 12C.
The Met Office added: "It will feel 'significantly colder' than it has done recently, especially in any showers and when exposed to the wind."
The weather tomorrow is not much better, as the day starts overcast, but further showers will develop and it will remain breezy.
More persistent rain is likely at times, particularly around midday and into the evening.
