The UK is bracing for a dramatic shift in weather as temperatures are predicted to drop by more than 15C this week, marking the end of a prolonged heatwave.

A cold front is set to arrive from the Atlantic, bringing with it substantial rain, particularly to southern regions.

Temperatures are expected to fall back towards seasonal norms, with some areas even dipping about 3C below normal by Thursday.5

After enduring 62 consecutive days without rainfall, parts of southern England are particularly in need of this change, as noted by the Met Office at a weather station in Wisley, Surrey.1

“After such a scorching summer, and with a temperature drop of more than 15C compared with last Thursday’s heat, it may feel surprisingly chilly,” a spokesperson from the Met Office stated.

The weather is expected to become more unsettled, with frequent sharp showers and potentially thundery downpours arriving from Wednesday into the weekend.6

“Even a few substantial bursts of rain will make a noticeable difference to the environment,” experts noted, highlighting the importance of this rainfall after a prolonged dry spell.

Additionally, continental Europe is also likely to experience wetter conditions as the main cold front moves southwards into France and Germany on Wednesday.7

Key Insight
“The cold front arrives from Monday night into Tuesday, with some parts of the UK falling about 3C below normal by Thursday. Southern England has endured 62 consecutive days without rain at Wisley, Surrey, making the upcoming showers a significant relief.”
