A new UK heatwave is set to bring rising temperatures, renewed health concerns, and water restrictions across parts of the country, with forecasters warning that conditions could peak at around 34C in the South East later next week. A week-long heat warning has now come into force, covering large areas of England as hot, dry weather builds again after an already warm start to summer.
The latest forecast from the Met Office indicates that temperatures will climb steadily from the weekend into next week, creating a prolonged spell of heat that is expected to last for around seven days. While conditions are not expected to reach the extremes of last month’s record-breaking heat, officials are still urging caution, particularly for vulnerable people.
This article explores the latest UK heatwave forecast, health alerts, hosepipe bans, and what residents need to know in the days ahead.
According to the Met Office, temperatures are expected to reach around 29C in southern parts of the UK on Sunday, before steadily increasing through the following week. By midweek, much of southern England could experience low 30s Celsius, with the highest temperatures expected in the South East.
Forecasters suggest that Thursday or Friday could mark the peak of the heatwave, with temperatures potentially reaching 34C in some areas.
Meteorologists have also highlighted a north south divide in weather conditions. Southern regions will experience the hottest and driest weather, while northern areas are expected to remain cooler with cloud cover and occasional rain.
Although the heatwave will be significant, the Met Office has said it is unlikely to match the intensity of previous extreme heat events earlier in the summer.
A key development this week is the introduction of yellow heat health alerts by the UK Health Security Agency, which came into effect at midday on Saturday.
These alerts apply across several regions, including the East Midlands, West Midlands, South East, South West, and eastern parts of England. The warning period currently runs until 11 July at 8pm.
The UK Health Security Agency has warned that even moderate heatwaves can place additional pressure on health and social care services. The main risks include:
Officials are advising the public to take precautions, especially during the hottest parts of the day, typically between 11am and 4pm.
Alongside rising temperatures, water companies are introducing restrictions to manage pressure on supply systems.
Southern Water has confirmed a hosepipe ban starting from 10 July at 12.01am, affecting customers in Hampshire and the Isle of Wight.
In addition, South East Water implemented a temporary hosepipe ban for customers in Kent from Friday.
The restrictions prohibit the use of hosepipes for non-essential activities, including:
Water providers say these measures are necessary to protect supplies during periods of sustained dry weather and increased demand.
The UK is expected to experience sharply contrasting conditions depending on location.
Southern England and parts of Wales will see the highest temperatures and longest periods of sunshine. Cities such as London could approach or exceed 30C on multiple days next week.
Northern England and Scotland, by contrast, are expected to remain cooler with intermittent rain and more cloud cover. This split pattern is typical during UK heatwaves when high pressure systems sit over southern regions.
Transport networks, workplaces, and public spaces may all be affected by heat related disruption, particularly in urban areas where temperatures tend to feel more intense due to the urban heat island effect.
Meteorologists from the Met Office have emphasised that this is expected to be a prolonged but not record breaking heat event.
One key concern is the duration of elevated temperatures rather than a single extreme peak. Sustained heat can place more strain on the human body, infrastructure, and healthcare systems than short bursts of very high temperatures.
The public is being advised to:
These simple steps can significantly reduce the risk of heat related illness.
Earlier this summer, the UK experienced a more intense heatwave, including a provisional June temperature record of 37.7C in Norfolk. That event was among the hottest on record for the month of June.
While the current forecast is not expected to reach those levels, officials warn that even slightly lower temperatures can still have serious impacts when sustained over several days.
The current heatwave is characterised more by its duration than its peak intensity, with temperatures expected to remain consistently high for around a week.
Repeated heatwaves in the UK are becoming more frequent, and climate scientists continue to study how rising global temperatures are influencing extreme weather patterns.
Extended periods of hot weather can affect:
As conditions evolve, authorities are likely to continue updating guidance and restrictions.
