Brits will be lashed by more heavy rain and thunderstorms amid warnings that other countries in Europe will see soaring temperatures in days.
Forecasters have warned that the UK is set to be a mix of sunshine and showers, with thunderstorms predicted in some regions.
Temperatures will be warm but nowhere near the highs that have been predicted this week for popular holiday destinations including Spain and Italy.
Weather maps have shown large swathes of red - temperatures regarded as dangerous - across most of Southern Europe over the next few days.
Temperatures may this week peak at a fierce 45C in parts of Spain, Greece and Italy, and in the latter at least three people have already died due to the heat. The heatwave - dubbed "Cerberus" - will see temperatures 10-15C higher than average for the time of year across much of the continent.
And in Prague, Czech Republic, where temperatures barely exceed 24C in June, the mercury is expected to hit a sweltering 34C by the weekend. North Africa is also set to suffer from extreme heat, where temperatures are forecast to reach 50C.
The Met Office has already lamented climate change in a stinging analysis of how hot it became in the UK alone last month. Now, responding to the forecast for most of Europe, the Met Office has warned of "health impacts and the potential for wildfires".
Grahame Madge, spokesman for the service, said: "The heatwave conditions which are affecting parts of southwest Europe and northwest Africa are expected to extend eastward eventually reaching the Middle East later in the week.
"Communities in the affected regions should expect health impacts and the potential for wildfires."
