London is bracing for another heatwave, with forecasters predicting a fifth spell of hot weather in mid-August. According to BBC Weather, temperatures are set to reach the heatwave threshold—28C or higher for three or more consecutive days—between Tuesday 11 and Thursday 13 August. While long-range forecasts are subject to change, the current outlook suggests the heat will persist, with the possibility of it extending beyond that period.
Met Office Predicts Earlier Heat Spike
The Met Office, however, anticipates the next heatwave could arrive sooner, starting as early as Sunday (August 2) and lasting through Tuesday (August 4). During this period, temperatures are expected to remain in the high twenties, which, while not the most intense heatwave experienced this summer, will still be uncomfortable for many.
In the meantime, Londoners can enjoy a brief respite with sunny but milder conditions, as temperatures are forecast to hover in the mid-twenties. This relative cool-down is expected to last until the next heat surge.
Possible Thunderstorms on Tuesday
Looking ahead to Tuesday (August 4), there is a chance of rain and thunderstorms in the mid-afternoon. Meteorologists currently estimate an 18% probability of thundery showers between 2pm and 4pm. While storms are not guaranteed, carrying an umbrella might be wise.
This forecast marks a shift from yesterday's predictions, which had suggested rain on every day between August 4 and 12—a welcome prospect for gardeners. The changeability highlights the difficulty of predicting weather far in advance.
Long-Range Outlook: Above-Average Temperatures
The BBC's long-range forecast, covering August 10 to August 23, states: "Temperatures are still most likely to be above the August average right across the UK into late August, and potentially at times well above, especially in the south." This indicates that the heat is unlikely to abate significantly in the coming weeks.
