Parts of England are forecast to experience a short-lived rise in temperatures this week, with highs reaching 25°C in several counties before cooler conditions reassert themselves across the UK. According to the Met Office, this brief period of warmth will affect mainly eastern and southern regions, contrasting with lower temperatures expected elsewhere. The pattern reflects a broader transition into autumn, during which variable weather is common.
Although the Met Office has not issued formal warnings, indications suggest unsettled conditions will follow shortly after. As reported by the Mirror, the warmer spell is not expected to last beyond the middle of the week.
Short Burst of Heat Follows Record-Breaking Summer
According to the Met Office, the summer of 2025 is expected to be the hottest on record for the UK. Based on data up to August 28, the mean average temperature stands at 16.13°C. If confirmed, this figure would surpass all previous years, placing 2025 ahead of:
- 2018 (15.76°C)
- 2006 (15.75°C)
- 2003 (15.74°C)
- 2022 (15.71°C)
- 1976 (15.70°C)
This summer also saw the country endure four separate heatwaves, with hosepipe bans and drought warnings issued in some areas as prolonged dry spells placed pressure on water supplies.
Warmest Conditions Expected in Eastern and Southern England
According to data cited by the Daily Express, temperatures on Wednesday, 3rd September are forecast to peak between 23°C and 25°C across parts of eastern and southern England, following several weeks of fluctuating late-summer conditions.
The warmer air mass is expected to remain in place for a limited time before a broader shift toward cooler weather patterns. Forecast models show that this temperature increase will be most noticeable in lowland areas and regions away from western uplands. This brief return of warmth will primarily affect the following counties:
- Norfolk
- Suffolk
- Cambridgeshire
- Lincolnshire
- Kent
- Greater London
- Surrey
- Berkshire
- Hertfordshire
- Buckinghamshire
- Bedfordshire
- Northamptonshire
- Leicestershire
- Rutland
- Nottinghamshire
- East Riding of Yorkshire
These regions, many of which are home to popular coastal towns and urban centers, are expected to enjoy one final spell of summer-like weather before a transition to autumn conditions takes hold.
Temperatures Set to Drop Sharply Across Much of the UK
Outside of the warmest zones, a significant cooling trend is forecast. In some inland areas, overnight lows could fall to 3°C, marking a stark contrast with recent heat. According to forecasts from WXCharts, this shift will be particularly noticeable in Scotland, Wales, and Northern Ireland, where daytime highs will remain subdued and the chance of heavy rainfall increases through the week.
The Met Office has outlined a complex weather pattern for the first half of September, driven by areas of low pressure likely to dominate:
Some heavy rain or showers are expected in places, most often in the west,” the forecast states.
“Thunderstorms and hail are also possible, as are some spells of strong winds if any deep areas of low pressure form in the vicinity of the UK. Some short-lived spells of drier and more settled weather are also possible at times, especially early and again late in the period, when they may last a little longer.
