Cool conditions will sweep in by Wednesday, bringing colder nights and single figure temperatures.
Scotland is expected to be the worst hit, where 60mph gusts are forecast and severe weather warnings are in place.
Met Office forecaster Helen Roberts told the Daily Mail: "There will be a noticeable drop in temperature from Monday following a humid night.
"This is due to a change in wind direction to a north westerly wind".

The weather is expected to improve by next weekend when a heatwave could return for the rest of the month.
