The mercury is set to soar this weekend with the hottest day of the year predicated for parts of the UK.
According to the Met Office, the south-east of England could see the mercury rise to 29C.
The joint warmest days of 2019 so far were April 19 and May 15, recording highs of 25.8C, in a year that saw all four of the UK nations reach their warmest Easter Monday on record.
A mixed weekend is forecast due to the high pressure dominating much of Saturday being replaced by low pressure on Sunday.
A Met Office spokesman said: "The heat tomorrow (Saturday) is going to be limited to south and east really, some parts of England and Wales, but with the main emphasis on the south-east corner and East Anglia.
"There will be some medium and high-level cloud around. It will make the sunshine a bit hazy at times so not necessarily wall-to-wall blue skies, it'll be feeling quite humid as well.
"A similar figure again on Sunday in the south-east. Although the heat will be much more limited, we could still reach those sorts of temperatures."
Northern England will be significantly cooler than the south on Saturday, with the average at around 18C.
"The dividing line really is northern England for tomorrow (Saturday)," the spokesman continued.
"Scotland, Northern Ireland and perhaps parts of northern England will not be necessarily particularly wet, but certainly a good deal cooler.
"We've got that rain pushing in from the west on Sunday, so Scotland will see some quite persistent rain on Sunday.
"Northern Ireland will see some rain and other western parts of England and Wales too."
The average temperature for June is 17C (62.6F) and it is likely that most of the UK should be warmer on Saturday.
