UK Heatwave Returns as Temperatures Could Reach 35C: What the Latest Hot Spell Means for Communities

The UK is facing another spell of intense summer heat, with parts of the country preparing for temperatures to rise into the mid-30s Celsius this week. This marks the fourth heatwave period of the year, continuing a pattern of unusually warm conditions that have affected many areas during the summer of 2026.

The latest hot weather is expected to be strongest across central, southern, and eastern England, where temperatures could reach around 35C at their peak. While some regions will experience sunshine and very warm conditions, others, particularly Scotland, Northern Ireland, and parts of northern England, are expected to remain cooler with cloud and rainfall.

Weather experts say this heatwave is likely to be shorter than previous hot spells seen earlier in the summer. However, health officials are warning that even a brief period of extreme temperatures can create risks, especially for older people, young children, and those with existing health conditions.

Where the hottest temperatures are expected

The UK is set to experience a noticeable contrast between the north and south during this period of hot weather.

Central and southern parts of England are likely to see temperatures rise between 25C and 32C over several days, with Wednesday expected to bring the highest temperatures. Some areas across the Midlands, south-east England, and eastern England could record highs between 30C and 35C.

London and surrounding areas are among the places expected to feel the strongest impact from the heat. Urban areas can become particularly uncomfortable during hot weather because buildings and roads absorb heat during the day and release it slowly overnight.

Meanwhile, Scotland and Northern Ireland are forecast to remain much cooler. Temperatures there are expected to stay mainly in the high teens or low-to-mid 20s Celsius, with showers and cloud continuing in many locations.

This difference in conditions highlights the varied impact of summer weather across the UK. While some people may be enjoying sunshine and outdoor activities, others may be dealing with unsettled weather and cooler temperatures.

Health warnings issued as temperatures rise

The UK Health Security Agency has issued heat health alerts because of concerns about the impact of rising temperatures on public health.

Amber heat health warnings are in place for areas including the East Midlands, East of England, London, and the South East. These alerts advise that significant effects are possible, particularly for health services and vulnerable members of the population.

High temperatures can increase the risk of dehydration, heat exhaustion, and other heat-related illnesses. Hot nights can also affect sleep quality, leaving people tired and increasing pressure on those who are already vulnerable.

Health officials recommend taking simple precautions during periods of extreme heat. These include drinking plenty of fluids, avoiding unnecessary travel during the hottest parts of the day, keeping homes as cool as possible, and checking on family members, neighbours, or friends who may need extra support.

Yellow heat alerts have also been issued for areas including Yorkshire and the Humber, the West Midlands, and the South West, where some impacts are possible but expected to be less severe.

July becomes one of the hottest months on record

The current heatwave comes after an already exceptionally warm summer.

According to the Met Office, July 2026 has recorded unusually high temperatures, with the UK’s average temperature for the month reaching 17.5C so far. This places July 2026 among the hottest months recorded in UK history.

Only July 2006, which recorded an average temperature of 17.8C, has been warmer. The ongoing heat has contributed to concerns about water supplies, agriculture, and the condition of natural landscapes.

Repeated periods of hot weather can place additional strain on infrastructure, including electricity networks, transport systems, and emergency services. It can also create difficult conditions for farmers, gardeners, and wildlife.

Dry conditions increase concerns about drought

Alongside the heat, a lack of rainfall is becoming a growing concern in many parts of the UK.

Although some areas received rain over the weekend, many of the driest parts of England saw little meaningful rainfall. Central, southern, and eastern England have been particularly affected by dry conditions.

Rainfall figures for England in July 2026 remain among the lowest recorded for the month. The limited rainfall has contributed to dry soil, reduced water availability, and increased wildfire risks.

Several areas have already introduced hosepipe restrictions affecting millions of households. Water companies have warned that continued dry weather could place additional pressure on supplies if significant rainfall does not arrive soon.

Dry vegetation has also increased the risk of wildfires. When grass, plants, and woodland become extremely dry, fires can spread more quickly and become harder to control.

When can people expect rain?

Forecasts suggest that some isolated showers may develop later in the week, but there is currently no indication of widespread or prolonged rainfall.

This means that although temperatures may eventually fall after the peak of the heatwave, dry conditions could continue.

Some locations have experienced long periods without measurable rainfall. Wisley in Surrey, for example, recorded 40 consecutive days without rain by late July.

The lack of significant rainfall is causing concern because high temperatures combined with dry ground can create a difficult environment for farming, wildlife, and water management.

How to stay safe during hot weather

During heatwaves, small actions can make a significant difference.

People are advised to:

• Drink water regularly, even if they do not feel thirsty.
• Avoid spending long periods in direct sunlight around midday.
• Wear lightweight clothing and use shade where possible.
• Keep indoor spaces cool by closing curtains or blinds during the hottest periods.
• Look after vulnerable relatives, neighbours, and friends.
• Never leave children, older people, or pets inside parked vehicles.

Employers and event organisers may also need to consider how high temperatures affect workers and visitors.

A summer of extreme weather

The latest heatwave is another reminder of how unusual weather patterns are becoming more noticeable in the UK. Periods of intense heat, followed by concerns about drought and water shortages, are creating new challenges for communities and public services.

While this week’s heat is expected to be temporary, the wider effects of a hot and dry summer may continue for some time. Monitoring weather forecasts, following official advice, and preparing for extreme conditions can help people stay safe.
