As Britain braces for sizzling temperatures, weather forecasters predict an imminent heatwave that will see mercury levels soar across England. Meteorological data suggests that 29 counties will experience temperatures of at least 26C, with some areas potentially reaching a scorching 32C by June 16. This dramatic temperature rise represents a significant shift from typical early summer conditions and has prompted weather experts to issue advisories for residents across affected regions.
Counties facing record-breaking temperatures
The forthcoming heatwave is expected to blanket much of England, with particularly intense heat concentrated across southern and central regions. According to long-term projections from Met Desk, which provides data for Ventusky and WX Charts, numerous counties will experience temperatures well above seasonal averages.
The counties anticipated to experience the most intense heat include:
- Somerset and Sussex in the southwest and south
- Greater London and surrounding Home Counties
- West Midlands and surrounding shires
- Greater Manchester and Lancashire in the northwest
- Yorkshire and eastern coastal counties
In total, 29 counties across England will face substantial temperature increases. Eastern regions including Norfolk, Suffolk, and Lincolnshire are expected to experience sustained high temperatures due to continental air flows from mainland Europe. Meanwhile, inland counties such as Derbyshire, Nottinghamshire, and Staffordshire will see temperatures climb steadily throughout mid-June.
Previously, soaring temperatures expected in southern England as UK weather forecast predicts 19C highs indicated a warming trend, but current projections suggest significantly higher peaks than initially anticipated.
Heat distribution across regions
The distribution of heat will vary slightly across the country, with some regional differences evident in forecasting models. Southern counties including Hampshire, Berkshire, and Buckinghamshire are predicted to see the earliest onset of high temperatures, potentially reaching the 30C mark by mid-afternoon on June 16th.
The following table shows the expected peak temperatures across different regions:
| Region | Counties Affected | Expected Peak Temperature (°C) |
|---|---|---|
| Southeast | Kent, Sussex, Surrey, Greater London | 30-32 |
| East | Essex, Suffolk, Norfolk, Cambridgeshire | 28-31 |
| Midlands | Warwickshire, Northants, Leicestershire | 27-30 |
| Southwest | Somerset, Gloucestershire, Wiltshire | 26-29 |
| Northwest | Greater Manchester, Lancashire, Cheshire | 26-28 |
While most of England will experience the heatwave, Scotland and Northern Ireland are likely to encounter cooler and wetter conditions due to low pressure systems extending from Iceland and Greenland. This north-south divide in weather patterns is typical during early summer heatwaves but appears particularly pronounced in current forecasting models.
Weather patterns driving the heatwave
Meteorological analysis indicates that this imminent heatwave stems from strengthening high-pressure systems positioning themselves close to the UK. This atmospheric configuration typically brings stable, dry conditions and allows continental air masses to influence British weather significantly.
According to BBC Weather forecasters, the period from June 16th to June 29th is expected to be “dry with some summer warmth.” Their extended outlook notes: “With a low pressure system lingering somewhere between Iceland and Greenland and extending at times towards parts of Scandinavia, Scotland and Northern Ireland will continue to be prone to slightly wetter, windier and cooler conditions.”
The current models suggest minimal likelihood of a prolonged cooler spell interrupting the heatwave, though short-term fluctuations remain possible. Weather experts emphasize that high-pressure dominance typically brings settled conditions but can occasionally trap moisture, leading to isolated thunderstorms despite generally clear skies.
Before the heatwave fully establishes itself, forecasters predict some unsettled conditions. Netweather TV’s Jo Farrow describes: “Clusters of showers begin to appear in the small hours of Friday working their way over Wales and England. The showers will ease by the evening as high cloud begins to appear from the west.”
Preparing for rising temperatures
As temperatures climb toward potentially record-breaking levels, residents across the affected counties should consider appropriate measures to manage the heat. Health authorities typically recommend increased fluid intake and reduced exposure during peak temperature hours, usually between 11am and 3pm.
The timing of this heatwave coincides with the traditional British summer season, when outdoor activities increase significantly. However, the intensity projected exceeds normal expectations for mid-June. Historically, such temperature patterns have been more commonly associated with late July or August.
For gardeners and agricultural workers, the sustained high temperatures combined with limited rainfall may present challenges. Water conservation measures might become necessary in some southern counties if high-pressure systems persist beyond the forecast period.
Weather updates will continue to refine these projections as June 16th approaches. The Met Office and other forecasting services typically provide incremental adjustments to their models, with Friday’s update expected to offer further insights into the duration and intensity of the coming heatwave across England’s 29 affected counties.
