Britain is set for another week of good weather after temperatures across the country hit more than 20C on Sunday for the first time this year.
Porthmadog in North Wales saw the warmest temperature, with the mercury reaching 22°C, the Met Office said.
Santon Downham in Suffolk had the biggest temperature swing over 24 hours, with a high of 19.5°C and a low of -1.4°C.
The warm weather is set to continue for much of this week, particularly in the south of the UK, with parts of London reaching 20C on Wednesday.
But forecasters warned the start of the week will be slightly cooler.
Sunday was the first day in 2020 where the temperature in the UK exceeded 20 °C!

Met Office spokesperson Nicky Maxey told the Standard: "It will be more cloudy and cooler on Monday with some rain clearing through the morning to leave a bright day with the odd shower.
"The rest of the week looks drier with sunny spells and temperatures once again likely to reach 20C in places."
This weekend's fine weather saw many take to parks and open spaces, despite Government warnings about the spread of coronavirus.
Prime Minister Boris Johnson urged Brits on Friday to continue taking the virus seriously and stay at home as much as possible.
And Health secretary Matt Hancock told ITV News on Sunday: "Going out and sunbathing, I can totally understand why people want to do that in this sunny weather.
"But going out from your home helps spread the disease and instead you should stay home, help protect lives and the NHS, and that way we can come through this faster."
Lambeth Council in south London said it was closing Brockwell Park, a popular green space, after around 3,000 visited on Saturday.
