There is a “outside chance” that the October record low of 25C may be surpassed, according to meteorologist Joanna Donnelly. She mentioned that certain regions of Ireland were expected to see 24C on Saturday when speaking on RTÉ's Today with Claire Byrne.

She stated that although Met Éireann was generally anticipating a clear sky, there may be clouds accompanying the warm weather.

It predicted that Saturday night will be “quite muggy,” with temperatures remaining between 12 and 15 degrees Celsius.

Sunday will bring a “mix of cloud and hazy sunshine” with temperatures between 18 and 22C, according to the forecast.

An “unusual” wave of warm weather is also expected to pass over portions of the UK this weekend.

There will be plenty of sunshine and mild temperatures in parts of England and Wales, much above the typical average of 13C for the month.

Forecasters predict Sunday's highs in the UK will be about 26C, making it warmer than Los Angeles in California and other European beach locations like Mykonos in Greece.

Greg Dewhurst, a meteorologist at the Met Office, stated: “The previous days have been quite hot in Europe, and that warm air is likely to drift in across quite a stretch of the UK on Friday and the weekend.

“Parts of Scotland are experiencing heavy rain, so the pleasant bursts of sunshine won't be felt everywhere.

“Friday's highs should be around 22C, Saturday's around 25C, and Sunday's around 26C, which we last experienced in October of last year.”

“It's not unheard of, but it's on the unusual side,” he continued.

In Gravesend, Kent, when the mercury soared to 29.9C in 2011, the UK's warmest October temperature was recorded.
