Make sure to hang on to your umbrellas for the next few days!
Met Office meteorologist Sophie Yeomans said it was unlikely the country would have higher temperatures than this.
It has been the hottest Easter Monday on record in all four nations of the United Kingdom, the Met Office has said.
Britain could see a record-breaking Easter weekend, with temperatures on track to break national records.
She added: 'It won't be one of the hottest temperatures we have had in April, the only thing it is going to break is some of the records for Easter Sunday and Easter Monday'.
The warmest Easter on record was on Easter Sunday in 1949, when temperatures were recorded at 29.4C in Camden Square in north London. And how did I spend the hottest day of the year so far?

Top national temperatures recorded on Easter Sunday are 20.7C in Aboyne, Scotland in 2015, 21.6C in Brynamman, Wales in 1984 and 19.4C in Armagh in Northern Ireland in 1924.
Steve Willington continued: "It now looks like more changeable and cooler weather will arrive from the northwest from Easter Sunday, however there remains the chance that southeastern parts of the country could remain warm and settled into Easter Monday".
London enjoyed 25C on Saturday, up from the average of 14C for this time of year, Cardiff saw 24C against an average of 13C and both Glasgow and Belfast notched up 23C, up from the usual 12C average.
Easter sunshine and sizzling heat will continue today with temperatures likely to soar across the UK.
However, today is not quite the nation's hottest day of the year so far, as yesterday's mercury reached 25.5°C in Gosport Hampshire. The Easter weekend has been dry, sunny and hot for most places across the United Kingdom, with Brits flocking to their nearest beaches and parks.
