UK could see record heatwaves in September for the first time, says Met Office

The UK could see a record six days of 30C heat in September for the first time, the Met Office has said.

Thursday was provisionally the hottest day of the year so far, with 32.6C recorded in Wisley, Surrey, the forecaster said.

The previous high for the year was 32.2C in June.

The heatwave has already broken the record for most consecutive days above 30C in September, with Saharan dust creating vibrant sunsets and sunrises in the clear conditions.

Thursday was the fourth day above 30C, beating the record of three days set on four previous occasions, most recently in 2016.

Met Office meteorologist Simon Partridge said: “If we do see 30C all the way through until Sunday, which it looks fairly sure it will be, that will be six days in a row that we have reached 30C.

“Previously in September we’ve only reached 30C three days in a row.

“So although it’s not the the hottest spell of weather we’ve had in September, in terms of prolonged hot weather it is twice as long as we have previously had.”

September’s highest daily temperature reading was 35.6C recorded on September 2 1906 in South Yorkshire, according to the Met Office.

But Mr Partridge said there was “no chance” that the September daily temperature record could be broken in the coming days.He said: “There is potential that we might get a little bit warmer over the weekend, not by a massive amount, but enough to make it the warmest day of the year so far again.

“It is always going to be around 32C, close to 33C at the maximum temperature.”

Prolonged heat above 30C puts older people and those with respiratory or cardiovascular conditions at greater risk, according to the UK's Health Security Agency, which has issued an amber heat warning for almost all of England until 9pm on Sunday.

A yellow heat warning is in place in the north-east of England until the same time.

The Met Office added that there could be heavy thundery showers across England and Wales on Sunday, but temperatures will remain high.

Temperatures are also expected to remain high overnight.

Mr Partridge said: “The biggest knock-on effect at the moment is those overnight temperatures because in parts of south-west England and Wales (Wednesday) night many places didn’t dip below 19C, which is not easy.

“We will continue to see temperatures in the mid to high teens overnight. A few spots could again not dip below 20C, so it’s very warm and muggy nights.”
