The upcoming week in the UK may experience the fourth heatwave of the year, with forecasts indicating temperatures could soar to a remarkable 40C. Weather models from the GFS system suggest a rise in temperatures starting on Tuesday, reaching 33C in eastern and southern parts of England and potentially hitting 31C even as far north as Yorkshire.
As the week progresses, Wednesday is expected to bring even warmer conditions, with projected highs of 35C in the south-east, 33C in the Midlands, and 32C along the England-Wales border. Contrastingly, Scotland and Northern Ireland are likely to experience cooler temperatures struggling to surpass the low-20s.
By Thursday, extremely hot weather is anticipated, with the possibility of reaching 39C in central, southern, and south-eastern England. This could surpass the current 2026 temperature record of 37.7C set in Lingwood, Norfolk on June 26.
Friday may see highs of 37C in eastern regions, while central and southern England could experience temperatures ranging from 35-36C. The weekend could bring even higher temperatures, with potential highs of 38C-39C, particularly in eastern England.
The peak of the heatwave is expected on Sunday, with the potential for highs of 40C, predominantly in eastern England. If realized, this could set a new all-time temperature record for the UK, surpassing the current record of 40.3C from the July 2022 heatwave.
Temperature anomaly maps indicate that England and Wales are forecasted to experience significantly higher temperatures than the seasonal average. According to GFS model data, up to 18 counties in England could witness temperatures exceeding 39C next week.
The Met Office forecasts a gradual increase in temperatures next week, with the possibility of reaching 30C in southern and eastern regions by Tuesday. The south-eastern areas could experience very warm to hot conditions throughout the week.
The Met Office states that there is a likelihood of meeting heatwave criteria next week, potentially marking the fourth heatwave episode of the year for some parts of the UK.
