A shift toward cooler temperatures is beginning across the UK, following an extended period of warm, sunny, and arid weather that defined the first half of the summer. Certain regions in England have endured over two weeks of heatwave conditions, with central parts recording their most significant dry stretch since 1997.
The nation’s third heatwave of 2026 is subsiding as northerly winds usher in cooler air. Despite this transition, substantial rainfall remains unlikely for most areas. This cooling phase might be short-lived, particularly in southern England and south Wales, where temperatures could soon climb back toward heatwave thresholds.
A slow-moving high-pressure system situated in the Atlantic is dictating these patterns, forcing a clockwise, northerly airflow over the UK. Northern and eastern Scotland, alongside eastern England, will experience the most noticeable impact, with temperatures dropping approximately 5C compared to previous weeks. Conversely, southwestern regions will see more modest cooling; Bournemouth, for example, is bracing for a potential third consecutive week of temperatures exceeding its 26C heatwave benchmark.
Rainfall remains sparse, with most areas expected to receive less than 5mm throughout the coming week. The summer has been notably parched, particularly in eastern and north-eastern England, where precipitation totals are at half of their usual seasonal average. Wisley in Surrey has marked 31 consecutive dry days, mirroring the broader three-decade dry spell affecting central England.
While some frontal systems might bring up to 30mm of rain to north-west Scotland, most inland regions are facing at least five more days of bone-dry weather. The Met Office’s recent State of the UK Climate report highlights that such extreme weather is becoming the new standard, noting that the UK has warmed by about 0.25C per decade since the 1980s as human-induced climate change increases the frequency and intensity of these heat events.
