UK weather maps turn red as temperatures shoot back up to 25C in middle of September

Parts of the UK are likely to bask in hot weather conditions in just two weeks after the Met Office revealed that summer 2025 was officially the warmest on record. WXChart maps have turned red for September 17 as the temperature level soar to sweltering highs of 25C.

The weather maps, prepared using MetDesk data, show that the southern parts of the UK are likely to bake in 25C. The weather agency explained that June and July saw consistently above-average temperatures this year. England experienced its hottest June ever recorded, while Wales and the UK as a whole marked their third and second warmest Junes, respectively. The heat persisted into July, which ranked as the UK's fifth warmest on record.

And now the latest maps suggest that the balmy conditions are likely to move into this month as well. The weather maps show areas around Birmingham, London, Luton, Worcester, Southampton, Oxford, Leicester, Leeds, and Liverpool will bake at 25C on September 17.

Other areas such as Plymouth, Cornwall, Norwich, Exeter and Manchester will see the temperature levels oscillating between 23 and 24C during the same period.

The northern parts of the country will also experience warmer temperatures, as the mercury levels will remain around 21C for Edinburgh.

Wick, Inverness, Aberdeen, and Glasgow are likely to see temperatures rise to 17 and 18C in September.

The hot weather maps come days after the Met Office issued a yellow warning of rain for several parts of the country. A yellow warning for rain is in place from midnight until 2pm on Wednesday, covering parts of southwest England and south Wales.

Rebekah Hicks, Chief Meteorologist at the Met Office said: "We're expecting a band of heavy rain and strong winds to move northeast through the first part of Wednesday, followed by heavy showers and the risk of thunderstorms. Some of these could bring hail and gusty winds, particularly in southern areas.

"Of course, the warning coincides with the first school run after the summer holidays for some, meaning a wet and potentially disruptive start to the day for many."

The Met Office's long-range forecast between September 17 and October 1 reads: "Low pressure may dominate for much of this period, bringing largely unsettled weather conditions with showers or some longer spells of rain at times. Some windy weather is also possible at times, especially if any deep lows form in the vicinity of the UK.

"There are likely to be some drier, more settled interludes though, particularly at the start of the period. Temperatures are likely to be close to or a little above average overall."
