It's set to turn a bit warmer over the coming days, with temperatures creeping into the low 20s in the warmest spots, the Met Office has said. According to reports, there will be nine consecutive days where the mercury nudges into the high teens and early twenties.
A UK heatwave threshold is met when a location records a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.
The forecast means that the UK should be as warm as holiday destinations like Malaga, Ibiza and Corfu, where temperatures will be around 22°C.

Spain and Portugal has seen storms and heavy rain in recent weeks because of an area of high pressure that has been sitting over the north of the UK. Read why where.
The service's forecast for Wales says that the warmer weather is set to start on Thursday when it will be "fine and dry with spells of sunshine and light winds".
It adds that it will "feel warm in the sunshine" with temperature highs of around 20°C.
The outlook for Friday to Sunday in Wales adds: " Breezy with some rain for a time on Friday. High pressure then building in for the weekend, meaning dry conditions, sunny spells and light winds."
The BBC UK forecast for the weekend says: "Most regions should remain largely dry on Saturday with some sunny spells expected. A fair start to Sunday, however, some light showery rain could develop across the Northern Isles in the afternoon. Temperatures over the weekend are forecast to be slightly above average."
And the Met Office long-range for the UK says that dry weather is likely throughout the first half of May.
The forecast for Sunday, May 8 to Tuesday, May 17, says: "There will be variable cloud and sunny spells to most areas. Northern regions are more likely to see a scattering of showers at the start, interspersed by bands of more persistent or heavier rain at times.
"Winds should be generally light to moderate, and coastal areas may also experience periods of low cloud or fog. The settled weather will continue, widespread through the second half of the period, with any rain confined to western and northern areas.
"Temperatures are likely to rise above average through the first few days, except nearer to the coast and perhaps in the far north, which may see slightly cooler conditions, and it is expected to become warm, perhaps very warm, later by the weekend."
The forecast is for more unsettled weather towards the end of the month, but temperatures will continue to be "above average".
