BBC Weather Watcher Pete’s PortalMany sun seekers in Northern Ireland regularly flock to the seaside town of Helen's Bay in County Down, and this Bank Holiday Monday was no exception.
The Carvalho family told BBC News NI the weather was a "surprise", so dad Freddy took a day off and they took a trip to the beach.
Meanwhile friends Claire Dummigan and Niamh Query brought with them a seaside picnic, including some non-alcoholic beverages.
"We try to get down on a regular basis, it's just such a beautiful part of the country," Niamh said.
"We're just so happy to be here on the beach and have this glorious weather."
Claire said she had plans to "jump in the sea very soon, have a lovely picnic and enjoy the sun while it's here".
She admitted getting into the sea is "hard" given the average Northern Ireland temperatures, but when you "come out you feel a million dollars – it just completely resets you".
Meanwhile, Kathryn Millar was enjoying the day at the beach looking after her grandchildren.
She said the warm weather was "unusual for Northern Ireland".
"It's just fabulous – three months of this would be great," she added.
"We're so lucky, really lucky, it's great... We'll stay here all day as long as the sun's shining, [we'll] sit and do absolutely nothing!"
