Latest weather models indicate that the UK could be on the brink of experiencing its hottest day ever as another heatwave is expected to grip the country. Temperature records have been shattered this week with temperatures surpassing 37C. The record for the hottest June day has been broken three days in a row, reaching a peak of 37.3C on Friday.
The GFS weather model now forecasts the possibility of the UK witnessing its hottest day in history. The current record of 40.3C, set during the scorching heatwave of July 2022, could potentially be surpassed. A new heatwave is poised to affect the country from July 8, with temperatures in the south-east reaching up to 35C. Central and southern England could experience temperatures of 30C or higher, with some areas, including Yorkshire, possibly hitting 33C.
On July 9, the GFS model suggests highs of 37C in southern England and up to 32C in parts of South Wales. The following day, July 10, could see temperatures soar to 40C in western and southern England, with central and southern parts of the country likely experiencing temperatures ranging from 37C to 39C.
July 11 is anticipated to be even hotter, with potential highs of 41C in western England and temperatures reaching 40C across regions from Yorkshire to London. Temperatures are expected to slightly decrease on July 12, with maximum highs of 38C mainly in the south-east. July 13 may see temperatures peak at 37C.
These soaring temperatures are likely to trigger an official heatwave, defined as three consecutive days of temperatures above the heatwave threshold. The threshold varies across different counties, ranging from 25C to 28C, with warmer areas like the south-east having a higher threshold. Temperature anomaly maps show the UK covered in red and black, indicating temperatures significantly above the seasonal average.
According to the GFS weather model, around 18 counties in England could experience temperatures exceeding 40C. The Met Office has highlighted an increased likelihood of further hot weather in the coming months, with the potential for thundery showers.
The Met Office’s forecast for July 12 to 26 suggests a higher probability of settled and drier conditions due to high pressure dominating the weather pattern. However, outbreaks of rain and thunderstorms are possible, particularly in northern regions. Temperatures are expected to be above normal, with intermittent periods of hot conditions throughout the period.
