UK Heatwave Forecast: Where Temperatures Could Climb Above 30C

Discover where temperatures are expected to rise above 30C across the UK, the latest Met Office forecast, heat health alerts, and tips for staying safe during the ongoing heatwave.

The UK is experiencing its third heatwave of the summer, with temperatures expected to remain well above average across many parts of the country. While the most extreme heat seen last week is forecast to ease slightly, forecasters say several regions could still exceed 30C over the coming days.

High pressure continues to dominate the UK's weather pattern, bringing prolonged sunshine, dry conditions, and unusually warm temperatures. Although some areas may experience isolated showers or thunderstorms later in the week, much of England and Wales is expected to remain hot and settled.

With heat health alerts still active across much of the country, residents are being urged to stay informed and take precautions as temperatures remain elevated.

Which Areas Could See Temperatures Above 30C?

According to the latest forecast, southern and western parts of England are expected to experience the highest temperatures this week.

Regions most likely to reach or exceed 30C include:

• South West England
• South East England
• London
• West Midlands
• Parts of East Anglia

While temperatures may not match last week's exceptional highs, many locations are still expected to remain comfortably above the official heatwave threshold.

Northern England, Scotland, and Northern Ireland are forecast to experience warmer than average weather, although temperatures are generally expected to stay below 30C.

Heat Health Alerts Remain in Force

The UK Health Security Agency (UKHSA) continues to monitor the ongoing hot weather.

Amber heat health alerts remain in place for:

• West Midlands
• South West England

Yellow alerts continue across several other regions until Wednesday, although warnings for North East England and Yorkshire have been lifted.

Heat health alerts are issued when prolonged hot weather could have significant impacts on health services, vulnerable individuals, and infrastructure.

Older adults, young children, people with existing health conditions, and those working outdoors are considered most at risk during extended periods of high temperatures.

Last Week's Record-Breaking Heat

The recent spell of hot weather has already produced remarkable temperatures across the UK.

Last Thursday saw temperatures reach 35.5C in Wisley, Surrey, making it one of the hottest days of the year.

Several locations also recorded exceptionally high June and July temperatures, continuing what has already become one of the warmest summers in recent decades.

The Met Office also confirmed that England experienced its hottest June on record, while Wales recorded its second warmest June since records began.

These figures continue a broader trend of increasingly frequent and intense heatwaves across the UK.

Why Is the Weather Staying So Warm?

Meteorologists say a large area of high pressure remains firmly established over the UK.

High pressure systems typically bring:

• Clear skies
• Long periods of sunshine
• Dry weather
• Light or easterly winds

As this weather pattern slowly shifts northwards, the hottest conditions are expected to move towards South West England.

Although temperatures in South East England may fall slightly compared with last week, conditions will remain warm enough for many areas to continue meeting official heatwave criteria.

Could Thunderstorms Develop?

While much of the country is expected to remain dry, forecasters have highlighted the possibility of isolated thunderstorms later this week.

The greatest chance of heavy showers and thunderstorms appears to be across:

• South West England
• Southern coastal counties

These storms could develop as warm, humid air interacts with slightly cooler Atlantic conditions.

However, any rainfall is expected to be fairly localised rather than widespread.

Day-by-Day UK Weather Forecast

Monday

Eastern cloud should gradually clear during the morning, leaving widespread sunshine across much of the UK.

Temperatures will remain very warm with a brisk easterly breeze, particularly along the south coast.

Most areas will stay dry throughout the day, although a few showers may approach southern coastal counties later during the evening.

Tuesday

Another largely sunny and dry day is expected.

Some low cloud could persist near north-east coastlines, while the South West faces a small risk of showers or isolated thunderstorms early in the day.

Elsewhere, temperatures will continue to feel very warm.

Wednesday to Friday

Most of the country is forecast to remain dry, sunny, and warm.

Winds are expected to ease, increasing the likelihood of hotter daytime conditions.

Forecasters are also monitoring a greater chance of thunderstorms developing across South West England, particularly towards Thursday and Friday.

How Long Will the Heatwave Last?

Current forecasts suggest there is no immediate return to cooler conditions.

Although temperatures may ease slightly in parts of southern and eastern England, many locations are expected to remain warmer than average well into the week.

Meteorologists believe high pressure will continue to dominate, supporting further periods of sunshine and dry weather.

Long-range forecasts also indicate that much of July could remain warmer than normal, although occasional thunderstorms may interrupt the settled conditions.

Staying Safe During Hot Weather

Public health officials advise everyone to take sensible precautions during periods of prolonged heat.

Helpful measures include:

• Drink plenty of water throughout the day.
• Avoid strenuous outdoor activity during the hottest hours.
• Wear lightweight, loose-fitting clothing.
• Apply sunscreen regularly when outdoors.
• Keep homes cool by closing curtains during the afternoon.
• Check regularly on elderly relatives, neighbours, and vulnerable individuals.
• Never leave children or pets inside parked vehicles.

Even temperatures around 30C can increase the risk of dehydration, heat exhaustion, and heatstroke if proper precautions are not taken.

What This Means for the Week Ahead

The UK's latest heatwave shows little sign of disappearing quickly. While the most extreme temperatures recorded last week are unlikely to be repeated everywhere, many parts of southern Britain can still expect hot, sunny conditions with temperatures climbing above 30C.

For many people, the weather will provide ideal conditions for outdoor activities and travel. However, the prolonged warmth also increases the importance of staying hydrated, protecting against sun exposure, and monitoring official weather updates.

With high pressure expected to remain the dominant weather pattern, much of the UK looks set to enjoy another week of summer sunshine, punctuated only by the possibility of isolated thunderstorms in the south-west.
