UK faces third, more extensive heatwave
According to the Met Office, vast expanses of the UK have met the official heatwave criteria, with hot, dry and sunny weather persisting into this weekend.
High pressure remains dominant, and temperatures are forecast to reach highs of 33-34 degrees Celsius in some regions over the next two days.
Met Office Chief Meteorologist Steve Willington said, "The current heatwave is more widespread than previous heatwaves this summer."
On Friday, the UK Health Security Agency and the Met Office issued an amber heat-health alert for much of England.
Under the weather-health alerting system in use, an amber heat-health alert indicates that weather impacts are likely to be felt across the whole health service.
At this alert level, health impacts may begin to be observed among the wider population. There is an increased risk for individuals aged over 65 and those with pre-existing health conditions, including respiratory and cardiovascular diseases, Xinhua news agency reported.
The Environment Agency has reported that England is experiencing the driest start to a year since 1976.
In June, reservoir levels declined at nearly three-quarters of monitored sites, with all regions now recording below-average water storage.
The agency has warned that continued dry conditions could place further pressure on water resources and the environment.
Tim Fox, fellow of the Institution of Mechanical Engineers and co-author of a report on climate change adaptation, emphasised that the recent heatwaves in Britain are not isolated events but are expected to become increasingly common in the future.
"As UK summers become hotter, with longer periods of high temperature extremes, the impact will reach far beyond personal discomfort," he said.
The heat will continue into Saturday, when temperatures could reach 31 degrees Celsius in parts of central and north-east Scotland, which would make it the hottest day of the year so far north of the border.
The heat spreading across the UK marks the third official heatwave of 2025 already.

Delhi likely to see light rain till July 18; AQI in 'satisfactory' range
Delhi and surrounding regions remained under pleasant weather conditions on Sunday after showers brought down soaring temperatures and offered relief from the heat and humidity earlier in the week. The city woke up to overcast skies and mild temperatures, following moderate rainfall on July 12. While the India Meteorological Department (IMD) has forecast a slight uptick in temperatures in the coming days, light rain and thunderstorms are expected to persist. No weather warnings have been issued for Delhi. The IMD has predicted very light to light rainfall, accompanied by occasional lightning. Maximum temperatures are likely to settle between 34 and 36 degrees Celsius. Cloud cover is expected to remain consistent throughout the day. Delhi pollution: Air quality remains 'satisfactory' Delhi's air quality remained in the 'satisfactory' category on Sunday. According to the Central Pollution Control Board (CPCB), the Air Quality Index (AQI) stood at 85 at 8 am on July 13. Air quality across the National Capital Region also showed improvement, with most locations reporting 'moderate' AQI levels. Delhi's 24-hour average AQI stood at 105 at 4 pm on July 12. In Gurugram, the AQI was 147, while Noida and Greater Noida recorded AQIs of 108 and 172, respectively. Ghaziabad's AQI stood at 107. As per CPCB guidelines, an AQI of 0–50 is classified as 'good', 51–100 as 'satisfactory', 101–200 as 'moderate', 201–300 as 'poor', 301–400 as 'very poor', and 401–500 as 'severe'. Weekly forecast: Delhi to remain cloudy with rain until July 18 The IMD has forecast continued rainfall in the national capital until July 18. Its latest update noted that the city is likely to experience mostly cloudy skies, with light rain, thunderstorms, and lightning throughout the week. A cyclonic circulation over northern Haryana and adjoining areas is influencing Delhi's weather, aiding in cloud formation and rainfall activity. Daytime temperatures are expected to hover between 33 and 35 degrees Celsius, with humidity levels ranging from 80 to 90 per cent. Yellow alert for Jharkhand between July 13–15 Meanwhile, the IMD has issued a 'yellow alert' for heavy rainfall across several districts of Jharkhand from July 13 to 15.

City Parks Cooler, Lack Facilities: Study
New Delhi: An audit of 50 parks across Delhi found that the shaded green areas were up to 20 degrees Celsius cooler in some parks than nearby unshaded concrete spaces outside. However, the report also highlighted issues such as limited access to the parks and the lack of basic amenities in many of them. The audit by green and social organisations found that the average temperature difference between shaded areas of parks and unshaded concrete right across their boundaries was 10 degrees Celsius. In one instance, even the concrete zones peaked at 53.3 degrees Celsius while tree-covered spots within the same park remained at 35 degrees, underscoring the critical cooling power of urban forests. However, despite this natural relief, eight out of 10 parks lacked drinking water facilities and none had official provisions for nests or birdhouses to protect urban birdlife from soaring temperatures. The report also stressed that parks are a necessity and not a luxury, advocating for their round-the-clock access to the public, especially in the densely packed residential areas with high heat stress.

This inequity, combined with the concretisation of urban forests, further enhances heat vulnerability in the capital. It stated that the nests or birdhouses installed were by local public and authorities. According to the report, the average surface temperature was 39.2 degrees Celsius in unshaded concrete spaces and 28.9 degrees under tree cover. About 78% of the parks lacked public drinking water, 73% lacked provisions for wildlife like water bowls, and only 28% had waterbodies, many of which were dirty or drying up. Additionally, 74% were closed at some time of the day, with 64% shut during night hours, limiting respite for residents in heat-stressed areas. "In many low-income neighbourhoods, the heat lingers late into the night, yet most parks are locked. It made us realise that parks aren't luxuries; they're life-saving infrastructure. Parks should be open 24/7, with water facilities and shade, as these are basic, life-saving necessities," said Priyanka, a member of the audit team from COHAS. "We also noticed how tree roots were choked with concrete, green patches were disappearing under paving and drinking water was missing," she added. "This audit clearly shows that green cover lowers temperatures dramatically, yet our policies prioritise concrete over canopies. The forest cover in Delhi is still under threat of being converted into big infrastructural projects," said Aakiz Farooq, climate & energy campaigner at Greenpeace India.
