London weather latest LIVE: Met Office issues rare ‘extreme heat’ warning as London hits 32C


emperatures hit a high of 32C in west London on Monday afternoon as forecasters predicted it could be the hottest day of the year so far.

The Met Office earlier issued a rare “extreme heat warning” for much of England saying “exceptionally high temperatures” are possible from Sunday.

Some modelling has suggested the mercury could reach 40C or beyond at the end of the week, smashing the UK’s record high of 38.5C recorded at Cambridge University Botanic Garden on 25 July 2019.

The Met Office said highs of 33C were expected in some areas on Monday afternoon, with Northolt, west London, recording temperatures of 32C as of 2pm.

The UK’s record high for this year currently stands at 32.7C – recorded at Heathrow on June 17.

The warm weather is expected to continue through the week, with highs in the upper 20s, before the mercury rises again to 31C in places such as London, Reading and Oxford.

This means parts of the country will be hotter than some of the world’s top beach destinations, including the Maldives and Marbella in Spain.

Met Office forecaster Greg Dewhurst said: “It will be very warm overnight going into Tuesday, remaining in the low 20s in cities, so many may experience an uncomfortable night.”

A Level Three Heat Health Alert has been issued by the Met Office and the UK Health Security Agency (UKHSA) from 9am on Monday to 9am on Friday in the east and south-east of England, with the rest of the nation having a level 2 alert in place.



Welcome to the Standard’s live weather blog on this sunny – and extremely hot – Monday. Stick with us for regular updates on the heatwave with the temperature tipped to climb as high as 31C or 32C in London this afternoon. Forecasters say the UK’s record high this – 32.7C at Heathrow on June 17 – could even be beaten.


It’s getting hot out there…

It’s already hit 29C in St James’s Park according to some temperature readings posted on social media. The Met Office is forecasting it’ll reach 31C by 4pm in the Royal Park.


Water companies urge people to not waste water during heatwave

Water companies are urging people not to waste water during the heatwave this week, because it can lead to some people not having any water running through their taps.

This is not due to a shortage but to do with companies not being able to treat water quickly enough to keep up with the demand.

However, no water company has introduced a hosepipe ban.

Thames Water has advised that people swap hosepipes for watering cans, and to use leftover water from paddling pools to wash the dog, or clean your car, among other tips.

Water companies have also urged people to find alternatives to cooling down rather than having cold showers, including taking a dip in a local swimming pool or the sea.


London under Level 3 health alert amid soaring temperatures

London is under a Level 3 health alert because of the heatwave, with temperatures expected to surpass 30 degrees celsius this afternoon.

The alert was issued for London, the South East and the East of England, from 9am today and will be in place until 9am Friday.

Officials are advising that particular care should be taken with those who are vulnerable, and that young children and pets should not be left alone in cars.

“Most of us can enjoy the hot weather when it arrives, but it is important to keep yourself hydrated and to find shade where possible when UV rays are strongest, between 11am and 3pm,” Dr Agostinho Sousa, of the UK Health Security Agency said.

“If you have vulnerable family, friends and neighbours, make sure they are aware of how they can keep themselves protected from the warm weather.”

Could temperatures reach as high as 40 degrees for first time this month?

Some computer forecast models have shown that UK temperatures could reach over 40C in mid-July – the highest ever recorded.

However, forecasters have said while this is technically possible, it is unlikely, as it depends on a number of factors.

A Met Office spokesperson told the Standard: “Some models have been producing maximum temperatures in excess of 40C in parts of the UK over the coming weekend and beyond.

At longer time scales temperature forecasts become less reliable, so whilst these maxima cannot be ruled out, they are still only a very low probability.

“A number of weather scenarios are still possible and at the current time, mid- or perhaps high-30s are looking more likely.”


Rare ‘extreme heat’ warning issued from Sunday

The Met Office has issued an rare amber warning for “extreme heat” for Sunday, advising that “exceptionally high temperatures are possible from Sunday, lasting into early next week”.

The warning, which covers most of England and parts of Wales, means that “population-wide adverse health effects are likely to be experienced, not limited to those most vulnerable to extreme heat, leading to potential serious illness or danger to life”.

The warning adds: “Substantial changes in working practices and daily routines likely to be required”.

The rare warning comes after some forecast models have shown that temperatures as high as 40C are possible at the weekend – which would be the highest ever recorded in the UK.

However, Met Office officials say temperatures of “mid- or perhaps high-30s are looking more likely”.


Electricity supply potential risk from ‘extreme heat’ at weekend – Met Office

The Met Office has issued a list of the possible side effects of the extreme heat expected from Sunday, which has prompted a rare heat-related amber warning.

Forecasters say the possible impacts are adverse health impacts on those vulnerable to heat, including sunburn, heat exhaustion and other heat-related illnesses.

They also warn of potential failure of heat sensitive equipment, meaning possible loss of electricity, water, or gas supplies.

Travel could also be affected, with heavy traffic and queues expected. They also advise there is greater potential for water-related incidents as people seek to cool off.


Council uses gritters to prevent roads ‘melting’

A council is preparing to deploy gritters in response to melting roads because of soaring temperatures.

Hampshire County Council said the machines will be spreading light dustings of sand.

This “acts like a sponge to soak up excess bitumen”, according to the authority.

Gritters are normally used to distribute salt during the winter to stop ice forming on roads.


Temperature hits 32C

The highest temperature recorded so far is 32C at Northolt in west London at 1.50pm on Monday, according to the Met Office.
