Britain is on course for another burst of intense summer heat as new weather maps forecast a significant rise in temperatures, with parts of the country expected to hit a sweltering 32°C. According to the latest model from WXCharts, the peak of this second heatwave is set to arrive on Monday, June 30.
The data shows a striking contrast in temperatures across the UK, with southern and central regions experiencing the brunt of the heat. London, Birmingham, and much of the South East are predicted to see temperatures soar well above 30°C, with the capital potentially reaching 32°C in the afternoon.
The heat will stretch across counties such as Essex, Kent, Surrey, Hampshire, and Oxfordshire, which are all expected to record highs around the 30–31°C mark.
The West Midlands will also feel the full force of the surge, with Birmingham forecast to peak at 30°C, while nearby Gloucestershire and Cambridgeshire aren’t far behind.
Here’s a list of the counties most affected by the upcoming heat surge on Monday, June 30, based on the forecasted 30°C+ temperatures:
Greater London
Essex
Kent
Surrey
Hampshire
Berkshire
Oxfordshire
Buckinghamshire
West Sussex
East Sussex
Hertfordshire
Cambridgeshire
Bedfordshire
Gloucestershire
Wiltshire
Somerset
Bristol
Dorset
West Midlands
Warwickshire
Northamptonshire
Leicestershire
Lincolnshire
In stark contrast, northern parts of the UK, including Scotland, Northern Ireland, and northern England, will remain significantly cooler.
Temperatures in places like Aberdeen, Inverness, and Belfast are expected to stay in the low to mid-teens, with maximums of just 12–14°C.
Forecasters are attributing the incoming spike to a plume of hot air moving north from continental Europe, where temperatures are also expected to surge.
This plume is likely to bring Mediterranean-style heat to parts of the UK, while areas further north remain under the influence of cooler Atlantic air.
Met Office have cautioned that the sudden increase in temperature could pose risks for vulnerable groups, including the elderly and those with pre-existing health conditions.
With the mercury pushing into the low 30s in densely populated areas, the risk of heat-related illness and transport disruption increases.
Authorities are advising the public to stay hydrated, avoid prolonged exposure to direct sunlight, and check in on neighbours and relatives who may be at risk.
The outlook for the first week of July remains uncertain, but current models suggest the heat may persist for several days beyond the 30th before easing slightly.
Should conditions remain dry and warm, this could mark the beginning of a more prolonged summer spell.
