Will there be another heatwave later this week? What the Met Office says
Parts of the UK could be in line to experience heatwave conditions by the weekend, forecasters have said, though many areas might not remain hot for long enough to be an official heatwave.
The hottest day of the year of 33.2C was recorded on Saturday in Charlwood, Surrey, as much of the country experienced four to five days of hot weather.
And while things cooled down considerably on Monday to the low 20s, forecasters have said there is a chance of temperatures soaring again as the week progresses.
BBC Weather lead presenter Simon King said the fresher conditions today are "likely to be just a temporary lull" before temperatures rise once more on Wednesday.
"By the end of the week a few locations across eastern England may even experience another heatwave," he said.
The BBC said temperatures will rise to between 26C and 29C across the Midlands on Wednesday, while it said London and the South East could experience a high of 29C on Saturday and 30C on Sunday.
The Met Office has also reported another hot spell is incoming, but Wednesday's and the weekend's highs may be broken up by cooler conditions on Thursday and Friday, meaning places could only see two days in a row of hot weather, not the three needed to meet heatwave thresholds.
Craig Snell, a meteorologist at the Met Office, told Yahoo News UK: "We could see a high in the south east on Wednesday of 28C. On Thursday and Friday, it will drop off to the mid-20s, so some places probably won't reach our heatwave criteria of three consecutive hot days.
"By the weekend there could be another spell of heat and temperatures could reach into the high 20s.
"There is potential for some fairly hot conditions to develop, especially across the south."
A heatwave is classed by the Met Office as a period of at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.
This threshold varies depending on the county in England, Scotland and Wales, while Northern Ireland has its own single threshold.
In London, for example, this threshold is 28C, while it is 27C on the south east coast, and 25C in Wales, Scotland and Northern Ireland.

Hurricane center says tropical system could target Florida while Tropical Storm Barry forms near Mexico
While Tropical Storm Barry formed in Gulf waters off of Mexico on Sunday, the National Hurricane Center began forecasting the season's next potential tropical system could form and threaten Florida. In its 8 a.m. tropical outlook the NHC said an area of low pressure from a remnant frontal boundary could develop near the end of this week near either the southeastern U.S. Atlantic of Gulf coasts. Its bubble of potential development sweeps across all of Central Florida. 'Some gradual tropical or subtropical development could occur thereafter as it drifts slowly just off the U.S. coastline,' forecasters said. The NHC gave it a 20% chance for development in the next seven days. The National Weather Service in Melbourne said expect a high chance of rain no matter what forms around the Fourth of July and into that weekend. 'The evolution of this stalled boundary and any features that it may help produce remains very low confidence and bears watching. However, the overall forecast thinking remains the same, regardless: high coverage of showers and storms looks to continue each afternoon and evening into next weekend, as deep moisture lingers,' NWS forecasters said. If it were to develop into a named storm, it could become Tropical Storm Chantal. That's because the second named storm of the 2025 Atlantic hurricane season formed Sunday morning in the Bay of Campeche off of the Mexican coast. As of 11 a.m., the center of Barry was located about 90 miles east-southeast of Tuxpan and 165 miles southeast of Tampico, Mexico with maximum sustained winds of 40 mph moving northwest at 6 mph. Tropical-storm-force winds extend out 35 miles. A tropical storm warning remained in effect for the Gulf coast of Mexico from Boca de Catan southward to Tecolutla. 'On the forecast track, the storm is expected to make landfall and then move inland over eastern Mexico later today or tonight,' forecasters said. 'A little more intensification is forecast before the system reaches the coast of eastern Mexico. Rapid weakening is expected after the system moves inland.' The system is forecast to drop 3-6 inches with some areas getting up to 10 inches across the Mexican states of Veracruz, San Luis Potosi and Tamaulipas through Monday. 'This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain,' the NHC stated. The slow start of the 2025 Atlantic hurricane season did not see the first named storm form last week. What would have been Tropical Storm Andrea remained out in the middle of the Atlantic, where it spun for less than a day with no threat to land. The National Oceanic and Atmospheric Administration, though, still forecasts this year 13 to 19 named storms this year, of which 6-10 will become hurricanes. Three to five of those are predicted to grow into major hurricanes of Category 3 strength or higher. Hurricane season runs through Nov. 30. _____

Heatwave peak set to bring 34C to parts of UK
Parts of the UK could see one of the hottest June days ever as a heatwave, now in its fourth day, peaks on Monday. Temperatures of 34C are possible in central and eastern parts of England according to the Met Office. UK temperatures in June have only exceeded this level three times since 1960. Glastonbury Festival has advised people to leave before 06:00 BST to avoid the head while Wimbledon could see its hottest opening day ever. An amber alert, in place since Friday, persists for five regions meaning weather impacts are likely to be felt across the whole health service. There is also a "severe" risk of wildfires according to the London Fire Brigade. The East Midlands, South East, South West, London and the East of England all fall under the amber heat-health alert and are likely to be subject to travel delays. Meanwhile, Yorkshire and Humber and the West Midlands are under a less serious yellow alert. The high temperatures mean all of these areas are likely to experience a rise in deaths particularly among the vulnerable, according to the UK Health Security Agency (UKHSA). However it won't be hot everywhere. "Cloud and some heavy rain will affect Northern Ireland and western parts of Scotland through Monday and temperatures will be suppressed to the mid to high teens," Met Office Chief Meteorologist Matthew Lenhert said. Night-time lows are only predicted to fall to 20C in some areas heading into Tuesday. This is the second heatwave of the year. London Fire Brigade assistant Thomas Goodall explained that this is why the risk of wildfires is "severe" as well as due to low rainfall in recent months. Guidance from the UKHSA recommends keeping out of the sun in the hottest part of the day between 11:00 and 15:00, wearing hats, sunglasses and suncream.

China's Scorching Heat Poses Summer Test for Electricity Grid
(Bloomberg) -- A sizzling start to July is on the cards for China, where nationwide temperatures are poised to climb almost 3C above historical averages in the first week of the month. Philadelphia Transit System Votes to Cut Service by 45%, Hike Fares Squeezed by Crowds, the Roads of Central Park Are Being Reimagined Sprawl Is Still Not the Answer Sao Paulo Pushes Out Favela Residents, Drug Users to Revive Its City Center Mapping the Architectural History of New York's Chinatown That'll pile pressure on electricity supplies as people crank up their air conditioners, demand for which has nearly doubled in the past decade. Swathes of eastern China, home to major population centers including Shanghai, Nanjing, and Hangzhou, will see temperatures around 35C to 39C (95F to 102F), with some places touching 40C, according to a forecast from the China Meteorological Administration. The region may face a 'long-lasting high temperature war,' the state weather bureau said last week. Key rice growing areas will also bake in the heat, threatening to damage the crop during a crucial development stage and risking lower output in one of the country's top-producing regions. As the mercury climbs, government officials will be feeling the heat in more ways than one: they must ensure stable power supplies even as demand spikes — potentially to record levels. The National Energy Administration expects peak electricity demand to be about 100 gigawatts higher this summer than last, the equivalent of needing to turn on all the power plants in the UK at once. Preparations have been years in the making. After major blackouts struck China earlier this decade, the authorities built up a massive surplus of coal, the country's mainstay fuel, amply supported by a world-beating roll-out of wind and solar power. There are already indications that authorities are gearing up for a sweltering few days. Last week, the National Development and Reform Commission, the country's top economic planning agency, took pains to emphasize the electricity grid's readiness for soaring temperatures. While the network is in better shape to take on peak summer demand this year, 'extreme and continuous high temperatures' can tighten power supplies, said an NDRC spokesperson, who also warned that extreme events like typhoons and floods can amplify threats to the grid. Rains may bring some relief, although heavy downpours — especially in the southwest, where the ground is already saturated after recent drenching — could threaten inundations. A broad band of precipitation is predicted to move through southwest, north and northeast China this week. In Beijing, cooling, thundery rains are forecast in the first half of the week, although the humidity could make it feel hotter than the thermostat suggests. For now, there is disagreement between major weather models on how long China's heat wave will last. Among those keeping a close watch will be coal traders: the benchmark price for thermal coal crept up from multi-year lows last week due to the sweltering conditions. On the Wire China's envoy to Canberra urged Australia not to be 'incited' by NATO's support for US demands to sharply raise defense spending and instead cooperate with Beijing to resolve regional disputes. Serbia has received assurances from China that it would support speeding up exports of materials critical for electric-vehicle production, benefiting companies like Stellantis NV, which operates a factory in the Balkan country, President Aleksandar Vucic said on Sunday. President Donald Trump said he has identified a buyer for the US operations of TikTok, the social media app owned by Chinese company ByteDance Ltd., but he won't provide details for two weeks.
