UK weather: Exact date heatwave will hit with Brits set to bask in 30C scorcher in parts as summer finally returns

BRITS will bask in a heatwave as early as early as TOMORROW in some spots - with temperatures set to soar to 30C.

The Met Office confirmed that official heatwave criteria will be met for large parts of the south in hours.

Official heatwaves could be observed as early as Tuesday in some parts - and people have been warned to expect "uncomfortably warm" nights, especially in the south.

Some could even experience tropical nights, where temperatures exceed 20C.

The highest overnight minimum temperature for September on record is 21.7C - but that could be beaten on Wednesday and Thursday.

Meanwhile, the UK Health Security Agency has issued a Yellow Heat Health Alert, meaning older and vulnerable people’s health is at greater risk and they could need to use more NHS services.

Warm weather is only dubbed a heatwave when daily maximum temperatures meet - or exceed - a local area's "threshold" for three days or more, the forecaster says.

The heatwave temperature threshold differs from region to region.

Today, forecasters said temperatures are set to peak on Wednesday and Thursday with 32°C possible in isolated spots in the southeast.

Met Office Deputy Chief Meteorologist Mark Sidaway said: “High pressure is situated to the southeast of the UK, which is bringing more settled conditions with temperatures on the rise through the first half of this week.

"While the highest temperatures are expected in the south, heatwave conditions are likely across much of England and Wales especially, with parts of Scotland and Northern Ireland also likely to see some unseasonably high temperatures.

“An active tropical cyclone season in the North Atlantic is helping to amplify the pattern across the North Atlantic, and has pushed the jet stream well to the north of the UK, allowing some very warm air to be drawn north. It’s a marked contrast to the much of meteorological summer, when the UK was on the northern side of the jet stream with cooler air and more unsettled weather.”

While temperatures are warm, it will be breezy in the West - which could make it feel cooler for some, the Met Office says.

Meanwhile those in the far North and West of Scotland will see periods of showery rain and some low cloud.

In the West, there's a chance of some very isolated thundery showers crossing areas from Tuesday - though this is unlikely to be widespread, forecasters say.

Earlier today, the Met Office said weather this week will be mostly dry with some very warm sun.

Tonight will be dry and mild, with the odd shower in the far south west.

Some smears of cloud and mist will develop overnight, but they will vanish on Tuesday morning - with forecasters predicting another "very warm to hot" day.

Met Office forecaster Chris Bulmer said: "Fine and settled conditions will develop and along with this we will see a rise in temperature across most parts of the UK next week.

"Many places can expect to see maximum temperatures rise to 25C or above for several days.

"Many areas will enjoy a fine period of weather with plenty of sunshine and temperatures are likely to be the highest for many since June or early July."

Met Office expert Amy Bokota added: "Most places are going to see wall-to-wall sunshine by the middle of the week, which is something we haven't seen for much of the summer.

"It's going to feel warmer than we would expect for the start of autumn, particularly in London and the South East.

"But it will also feel humid and muggy in some areas, with temperatures in parts of the country staying above 20C overnight, making for uncomfortable sleeping conditions."
