The Met Office has issued a rare amber weather warning for extreme heat, external for parts of England on Thursday, where temperatures could peak at 38C.

The highest temperatures will be in parts of the east, south-east and the Midlands and may lead to impacts on transport, infrastructure and health.

The last time we saw temperatures above 36C in August was 2020 when 36.4C was recorded at Heathrow and Kew Gardens.

The Met Office warning runs from 0900 BST until 2359 on Thursday, which is when the summer’s latest heatwave reaches its peak.

If the temperature does hit 38C, it would equal this year’s top temperature of 38C recorded at Lingwood in Norfolk on 26 June.

The UK’s health security agency has also issued amber heat health alerts, which are currently in force across most of England.

Heat health alerts, external warn the public and medical professionals when periods of hot or cold temperatures pose a threat to health.

The UK’s Health Security Agency (UKHSA), which issues them, is warning that significant impacts are likely across social and health care, including a rise in deaths.

The amber heat health alerts are in place until Friday evening to cover high and even extreme temperatures expected through this week.

During the peak of the heatwave temperatures across England and Wales will widely be in the low to mid-30s Celsius.

The only region in England without an amber alert is the North East which has been given a less intense yellow alert for the same period.

It comes after drought officials declared 71.3% of England is now in drought.

It has been a remarkable summer so far with temperatures remaining above average for most of it.

Even in the “cooler” spells, they have only come down to near the average for the time of year.

On Tuesday, the hottest weather will be around east Wales, the Midlands and central parts of southern England where temperatures will be around 27 to 30C (81-86F) – well into the heatwave temperature thresholds.

It will be a little cooler in East Anglia, London and south-east England, where it will be 22 to 26C.

The predicted temperatures, which are expected to rise as the week continues, have prompted the Met Office to issue an extreme heat warning for Thursday.

The hot weather will intensify and be more widespread on Wednesday.

In an area from South Yorkshire to east Wales, Somerset and east across England temperatures will be in excess of 30C.

Some of the warmth will spread further north into northern England, Scotland and Northern Ireland with temperatures into the low to mid-20s.

The hottest weather will be around the Midlands and south-east England with 31 to 33C.

By Thursday and Friday, extreme heat is most likely in parts of the Midlands, eastern and south-east England where temperatures could be as high as 37 or 38C.

As heat builds throughout the week, overnight temperatures will stay relatively high bringing some uncomfortable nights for sleeping.

Minimum temperatures may not go lower than 16 to 18C across England and Wales.

There is also a possibility of a “tropical night” – where temperatures remain above 20C all night – in south-east England.

The highest temperatures in the heatwaves of June and July were 38C and 35.5C respectively.

For the first time in recorded history we are expecting a temperature higher than 35C to have been recorded in the UK for four consecutive months – underlining that this has been a year like no other.

On Monday afternoon the National Drought Group announced the East Midlands, Lincolnshire and Northamptonshire, Kent and East Sussex, and Solent and the South Downs were the latest areas to move into drought status.

This means that most of England – away from northern areas – are in official drought, with 45 million people living in a drought area and over 27 million with water restrictions, according to the group.

The announcement comes with no rain in the forecast through most of this week across England and Wales.

We have to look towards Sunday, where there are some signs of rain coming into the UK from the Atlantic.

Low pressure bringing rain-bearing weather fronts will move in across Wales and southern England and – for some – a spell of rain.

While this does not currently look to be particularly heavy or persistent, there could be the first bit of proper rain for many in nearly two months.

There could be a few showers at times across Scotland and Northern Ireland in the coming days, but these will be localised with most areas staying dry.

Longer-range forecasts are always subject to change but there may be a little bit more into next week – but the amount of rain in any location may still be highly variable.

Beyond that, high pressure and more dry conditions look to be dominating the final week of August.
