Third heatwave to hit next weekend
Temperatures could climb into the low 30s and remain high at night, making sleeping uncomfortable.
It follows a weekend of cooler air, cloud and rain in most of England, and a yellow warning for thunderstorms in the east of the country on Sunday.
Marco Petagna, a senior meteorologist at the Met Office, said: 'I think Wednesday is probably going to be the day when we could start to reach the thresholds of 25C to 28C, depending on where you are.
'But of course, you need three days at those temperatures for it to be able to be called a technical heatwave.
'So, although the temperature will be reaching the criteria, we probably won't actually reach an official heatwave until around Friday, to give the three consecutive days at those temperatures.'
He added temperatures would climb through the week, reaching at least 30C by Friday and Saturday.
Uncomfortable nights
'At the weekend, we could just start to see humidity increasing a little bit as well and nighttime temperatures look like they are going to be, so it will be starting to become more uncomfortable by night,' said Mr Petagna.
The duration of the hot spell remains difficult to gauge, and there are uncertainties about just how high temperatures will rise.
It also appears as though the UK will avoid the stifling weather of the high 30s and low 40s seen in the Mediterranean.
Mr Petagna said: 'It's a bit of a question mark going through the weekend early next week as to how long the heat will last and how high the temperatures will get, because some models are sort of pushing the heat away a bit more quickly, whereas others keep the heat going.
'At this stage it looks as though certainly into next weekend, we should hold on to hot weather across the south of the UK and temperatures could again certainly get into the low 30s in a few spots.
'And we are going to see some very high pollen and very high UV levels as well.
'But at this stage, we've managed to escape some of the very highest temperatures, those seen across Spain and Portugal in particular, where it has reached the mid-40s.'

The UK's third heatwave of the summer is imminent
The UK is set to experience its third heatwave of the summer, with temperatures expected to exceed 30C in some areas this week. The Met Office has warned of warm and uncomfortable nights as temperatures are forecast to climb from Wednesday. An official heatwave is anticipated by Friday, requiring three consecutive days of high temperatures to meet the criteria. Temperatures could reach the low 30s by Friday and Saturday, with increased humidity making nights uncomfortable. High pollen and UV levels are also expected, though the UK is likely to avoid the extreme temperatures seen in the Mediterranean. How long will the third heatwave of the summer last and how hot will it get?

Met Office reveals prediction for weather on the Twelfth
Marchers and spectators attending Twelfth events can expect warm weather with a lingering possibility of rain, according to the Met Office. The Grand Orange Lodge of Ireland has released full details for all parades taking place on the Twelfth of July this year across NI. Thousands of people will take part in parades across Northern Ireland with many tens of thousands more spectating. Bands and marchers will take to the streets at 18 locations across all six of Northern Ireland's counties to mark the 334th anniversary of the Battle of the Boyne. This year Dundonald will host a Twelfth demonstration for the first time in more than 50 years. It will join 18 other venues across Northern Ireland including Belfast, Ballymena, Kesh, Coleraine, Keady Coagh, Sixmilecross, Augher, Dromara, Dundrum, Kilkeel, Cullybackey, Rasharkin, Carnlough, Lisburn, Glengormley and Maghera. The Twelfth demonstrations in Northern Ireland will follow the traditional Rossnowlagh parade held in Co Donegal on the preceding weekend on Saturday 5 July. Looking to The Twelfth, Senior Operational Meteorologist at the Met Office, Becky Mitchell, said: 'At the moment, Saturday is most likely to be dry, warm and sunny with light winds. 'Temperatures are most likely to be in the low to mid 20s. 'However there is currently a small chance that rain may start to move in from the west towards the end of the day.' In terms of the overall forecast for the week, Ms Mitchell said: 'This coming week is expected to be largely dry, and increasingly sunny and warm across Northern Ireland. 'Monday will be dry and windy with plenty of sunny spells. The wind will make it feel rather cool with a top temperature of 19 Celsius. 'Tuesday and Wednesday may turn a little cloudier with a few spots of light rain, and temperatures slowly climbing into the low 20s. 'Thursday, Friday and Saturday are expected to be dry and sunny as high pressure builds in. Temperatures are currently forecast to reach to low 20s in the sunshine, possibly getting close to the mid 20s for the start of the weekend. 'Sunday is currently uncertain – dry and sunny weather may hang on, or we may start to see rain push in from the west.'

Seine swimming spots close one day after 102-year ban is lifted
Rain has forced the closure of all three swimming sites on the River Seine in Paris. Heavy downpours overnight potentially washed sewage and other waste into the river, forcing the authorities to put up red flags at the designated zones: Bras Marie in the centre, Bras de Grenelle to the west and Bercy in the east. The ban came a day after the swimming spots were opened to the public after a 102-year ban on bathing in the river. The sites will remain closed until at least Monday, the council said. Another site along the Canal St-Martin, on the northeastern side of the city, was set to open on Sunday but remained closed. Officials said the downpour 'compromises water quality'. About 3,000 Parisians and visitors rushed for a dip on Saturday after decades of clean-up operations, which were accelerated by the 2024 Paris Olympic Games. Triathlon and open-water swimming events were held in the river last summer, but heavy rain led to six of the 11 races being cancelled. Anne Hidalgo, the mayor of Paris, has claimed the reopening as a key legacy of the Olympics. The council had been striving to lift the swimming ban since 1988, when Jacques Chirac, then the mayor of Paris who became president, promised to clean it, predicting that he would one day swim in it. Chirac, who served 12 years as president and died in 2019, never did. After the temporary closure on Sunday, Ariel Weil, mayor of the central Paris district, which comprises the first four arrondissements, posted on X: 'These are unfortunately the hazards of open water swimming. We'll see you on the Seine as soon as the weather is better.' Mockery of the closures also appeared on social media, mainly citing the €1.4 billion spent on improving the water quality of the river in the years before the games. Despite widespread doubts, the authorities said the water quality met European standards, and that levels of E. coli, enterococci and other bacteria were well below dangerous thresholds on most days. They had warned that sites would be closed if rain threatened sewage overflow. • Seine failed water standards eight days out of ten As well as the Paris swimming zones, 14 areas are open for bathing outside central Paris on the Seine and Marne rivers.
