Scorching UK Heatwave: Expected Highs Reach 30 Degrees Celsius in Certain UK Regions This Week
UK Weather Forecast: Dry and Warm Conditions with Thunderstorm Risk
The UK is experiencing a mix of weather conditions on Wednesday, August 6, 2025. Most areas are enjoying dry spells with sunny intervals, except for northern Scotland where there is more cloud and some patchy rain early in the day, which is expected to clear later. Temperatures range from around 15°C to 23°C across the country [1][3].
Looking ahead, the weather is expected to remain mostly dry with the best sunshine in the north, while Friday will bring patchy rain in northern areas but remain dry and warm in the south. There is a risk of thunderstorms, especially in the Midlands, East Anglia, and Southeast England, due to surface heating beneath cold upper-level air, with a 40% chance of storms in southeast England and possible localised flooding from heavy cells [2].
Southern Water has already brought in a hosepipe ban due to the exceptionally dry weather, and other water companies are likely to follow suit. This comes after the country has experienced its driest start to the year since 1976 for England, and the current heatwave is the third of the year, with temperatures soaring past 30°C (86°F) in parts of the UK last week [4].
London is forecast to peak at 30°C (86°F) tomorrow, and other areas in southeast England will push towards the high 20s on Friday. The average temperature in July in these areas is about 23°C (73°F) [5]. However, the unsettled weather is forecast to spread across more of the UK over the weekend, with a chance of heavy rain and thunderstorms across the country [6].
In related news, a yellow thunderstorm warning has been issued for much of Northern Ireland from 11am until 8pm today. Heavy showers and a few thunderstorms may cause disruption, particularly to travel [7]. Between 30mm and 40mm of rainfall over a few hours is expected in Northern Ireland, according to the Met Office [8].
Mr Vautrey predicts Friday as the peak of the current hot spell [9]. Restrictions like watering gardens, filling paddling pools or washing cars would come in for households in Hampshire and the Isle of Wight from Monday [10].
Last month was the hottest on record for the country [11]. Despite the current heatwave, it's worth noting that areas to the north aren't expected to see the same high temperatures as the southeast [12].
Recent notable weather includes the passage of Storm Floris earlier in the week, which caused strong winds and heavy rain, particularly in Scotland and Northern Ireland, but it has now moved away [13].
In summary, expect mostly dry and warm conditions across much of the UK today and the next few days, with localized rain and showers mainly in northern and western regions, and an increased risk of thunderstorms in eastern and southeastern England through the week.
The UK weather forecast suggests that the dry and warm conditions may be disrupted by thunderstorms, particularly in the Midlands, East Anglia, and Southeast England, as these areas have a 40% chance of storms due to surface heating beneath cold upper-level air. The current heatwave, the third of the year, has already led to a hosepipe ban in Southern Water, with other water companies likely to follow suit due to the exceptionally dry weather.
