Exact date heat forecast to return to UK after 26C heatwave covered Britain

Charts have revealed exactly when and where warmer conditions will pick up again for the country – though not without a cooler period first

The UK’s recent warm spell which saw highs of 26C in parts earlier this week is set to disappear briefly before making a sharp rebound, new weather maps show.

Charts have revealed exactly when and where warmer conditions will pick up again for the country – though not without a cooler period first.

Maps by WXCharts show as of Wednesday (April 15), a cooler airmass will cast across the country with maximum temperatures to sink between 10C to 13C for most. The South and South-east will be slightly warmed at 14C to 17C while the cooler snap will be felt more keenly across Scotland and England, where highs plummet to 7C and 11C.

Fortunately, the forecast indicates the cooler air is short-lived as by Sunday next week (April 20), temperatures will start to pick up again.

The maps show southern England, including London and the South East, could reach 17C to 19C, while the Midlands and Wales are forecast to sit around 14C to 17C. Further north, temperatures remain more subdued, ranging from 9C to 12C.

The warm air continues into Tuesday, April 21, with much of southern England climbing to 18C to 20C. Central areas are expected to reach 16C to 18C, while northern England and Scotland lag slightly behind at 10C to 13C.

The broader pressure chart for mid-April supports this shift, showing cooler air dominating around April 15 before milder conditions push back in from the South.

The Met Office long-range forecast also predicts some mixed conditions that shows signs of improving later into the month. The forecasters find from April 15 to April 24, conditions will be “changeable” at first, with low pressure bringing showers or longer spells of rain, particularly in the North-west, alongside some strong winds.

Meanwhile, the South-east is likely to stay drier and brighter, and later in the period, weather may turn more settled, especially in northern areas, though parts of the South could still see rain at times.

Temperatures overall are expected to be near or slightly above average, reinforcing the signal from weather maps that any mid-month cool spell will be temporary, with milder spring conditions quickly returning.
