UK Weather: Freakish 500-mile 'African plume' brings 23C Indian summer for Halloween

It could be sweltering trick or treat indeed this Halloween thanks to a fiendishly hot 'African plume' which could be set to deposit temperatures of 23C across Britain

A freakishly-hot 500-mile wide ‘African plume’ will give Britain a 23C (73F) Indian Summer ahead of Halloween - capping our hottest year ever.

Temperatures will be hotter than 21C Malibu in a warm run starting tomorrow (Mon) and lasting for up to six days, with super sunny spells for all.

And this is one U-turn we can all cheer – as the surprise sizzle comes after the forecast for the period previously looked drab.

Now hot air from Africa - shown on a weather map (attached) - means 17C weekend highs jumping to nudge 20C tomorrow, (Mon) with up to 22C or 23C by Wednesday, and heat around 20C set to continue to the weekend.

There will be some showers for all between the sunny stints.

The South will be hottest but the North is also set for a warmer-than-average 17C.

And more good news is mild conditions are set to continue up to Halloween on October 31.

Netweather forecaster Nick Finnis said: “Some computer models show 22C or 23C by midweek, bringing an Indian Summer.

“An exceptionally-warm plume of air from northwest Africa looks like being pumped across Europe and to Britain, with up to the low 30s in France, and over 20C in southern Britain.”

Met Office forecaster Marco Petagna said: “There’s a good signal for higher temperatures thanks to a southerly airstream with very mild or warm air.”

A Met Office forecaster said: “Sunday has sunny spells for many, with Monday dry with sunny spells in the South as rain clears the North.

“Tuesday is mostly fine in the North, with high pressure from Wednesday bringing generally settled conditions, although with some bands of rain spreading.

“The South and West are likely to be mild during the period to October 28, with sunny spells between showery periods.”

The out-of-season warm burst is set to help confirm 2022 as Britain’s hottest year ever recorded.

January to September was the hottest first nine months of the year since Met Office records began in 1884.

October so far is 1.5C warmer than the month’s overall average temperature, Met Office figures for central England show.

Dr Mark McCarthy of the Met Office’s National Climate Information Centre said: “It was the warmest year so far up to the end of September, with each month since January being warmer than average.

“2022 is on track to be one of the warmest years on record if warmer-than-average conditions persist.”
