Britain is set to bask in a 23C mini-heatwave as scorching May temperatures sweep across 28 counties, according to WX Charts maps. A surge of warm air is shown pushing into the UK, sending temperatures well above the seasonal average for late spring.

The charts indicate the heat will peak at around 6pm on May 1, with parts of the south-east reaching highs of 22C to 23C. Much of England and Wales is expected to enjoy the warmest conditions under largely dry skies. The maps also show a clear north-south divide, with Scotland remaining significantly cooler. Temperatures there are forecast to sit closer to the low to mid-teens at the same time. The widespread warmth is being driven by a settled weather pattern shown across the UK. While not meeting official heatwave criteria, it will still feel unseasonably warm for this time of year.

Wales (5):
Pembrokeshire, Cardiganshire, Carmarthenshire, Glamorgan, Brecknockshire

Midlands (4):
Staffordshire, Warwickshire, Worcestershire, Gloucestershire

South West (4):
Cornwall, Devon, Somerset, Dorset

South & South East (6):
Wiltshire, Berkshire, Oxfordshire, Hampshire, Sussex, Surrey

Greater London & Home Counties (5):
Middlesex, Essex, Hertfordshire, Buckinghamshire, Bedfordshire

East Anglia (3):
Cambridgeshire, Norfolk, Suffolk

The temperature gradient on the charts reveals a steady drop in values moving northwards across the UK.

This creates a clear divide between much warmer conditions in the south and cooler air further north.

Rainfall maps for the same time frame indicate patchy areas of precipitation rather than widespread rain.

These showers appear most prominent across parts of central and eastern England.

Despite this, many regions are still expected to remain warm during the day.

The charts show how temperatures and weather patterns vary across the country simultaneously.

Based on the data shown, the warm spell is expected to be relatively short-lived .

Even so, it will bring a brief burst of early summer warmth for much of the UK.
