Weather models suggest the UK could experience an official heatwave from June 17 to 19, with temperatures potentially reaching 32C in parts of England. The GFS model indicates that the mercury will climb above the heatwave threshold for three consecutive days, meeting the criteria for an official heatwave.
According to the data, temperatures will begin rising on June 17, with highs of 28C in the south-east, 27C in East Anglia, and 26C in the north-west and Midlands. Scotland and Northern Ireland are expected to be cooler, with temperatures in the low 20s.
On June 18, the south-east could see 30C, with 29C possible as far north as Yorkshire. Parts of Northern Ireland might reach 26C, while Wales sits in the mid-to-high 20s. The hottest day is forecast for June 19, when 13 English counties could experience highs of 31C or more, with the south-east potentially hitting 32C.
The Met Office's long-range forecast for June 18 to July 2 notes that high pressure will bring drier conditions initially, with temperatures above normal. However, towards the end of June, low pressure may bring heavy showers and thunderstorms, particularly in the south, where it could also become hot.
