The Met Office has forecasted a new heatwave for the UK this June, with temperatures expected to rise to 34°C in parts of southern England. This heatwave, characterized by 'very warm or hot conditions', is anticipated to peak around mid-June as high pressure builds across the country. The latest long-range forecast from June 13 to June 22 suggests a transition to a more settled weather pattern, particularly noticeable in southern and eastern regions, while the northwest may remain cloudier with occasional rain. As the high-pressure system strengthens, temperatures are likely to climb, with many areas experiencing highs in the mid-to-high 20s. London, the South East, and East Anglia are expected to see temperatures breach 30°C, while Scotland and Northern Ireland will remain cooler, generally in the mid-teens to low 20s. If forecasts hold, this could mark the first widespread heatwave of the summer, with conditions significantly above seasonal norms. The Met Office defines a heatwave as temperatures meeting specific thresholds for at least three consecutive days, varying by location.
