The Met Office's long-range forecast indicates an increased risk of heatwaves and heat-related impacts, especially during the first half of the autumn period. This comes after Londoners have already experienced five heatwaves this summer, with temperatures reaching a sweltering 38.1°C, making it the hottest summer ever recorded.
Forecast for Late August to Mid-September
According to the Met Office's long-range forecast for August 30 to September 13, 'there is a chance that late-season hot spells or heatwaves develop, especially in the south.' The forecast suggests September will bring a mixture of showers and hot spells, followed by 'drier, more settled weather, especially in the south and east' for the second half of the month.
The forecast added: 'Temperatures will probably be near normal at first, but may turn warmer later with a chance of some hot periods in the south.' The Met Office also warned of risks of thunderstorms and flooding throughout early autumn.
Uncertainty in the Long-Range Outlook
However, this forecast is not certain and could easily change. The Met Office said that the signals for a heatwave in later September were currently 'very weak', meaning it is probably too soon to tell the exact date of the heatwave, and whether it will definitely happen at all.
Context and Preparation
The UK is bracing itself for the sixth heatwave of the summer, following a season that has already seen record-breaking temperatures. The Met Office's long-range forecast for September, October, and November has highlighted the potential for continued warm weather, particularly in the southern parts of the country.
Residents are advised to stay updated with the latest forecasts, as the situation remains fluid and the exact timing and occurrence of any heatwave are still uncertain.
