Met Office plays down rumours of 'African plumes'

A forecast from Exacta Weather had said temperatures could regularly rise into the 30s this summer as hot air masses swept up from Africa, but the Met Office has said this is unlikely.

Honor Criswick, a Met Office meteorologist, said the event would be “unprecedented, but not impossible.”

Speaking to The Independent, she said: “We had a similar set-up last summer, though there were additional factors at play, with a high to the east of the UK bringing hot air up from the south/southeast.”

She added that the rising temperatures were “consistent with our warming climate”, saying: “Outlook forecasts are for the average conditions over the UK as a whole, for the period as a whole, so we can expect regional variations.

“So far for May, there is a higher than normal chance of warmer temperatures, however near average or cool conditions remain possible. Looking ahead into June and July, the chance of it being hot is higher than normal however near average temperatures remains the most likely outcome.

“There is also a greater than normal chance of impacts from hot weather such as heatwaves."
