BBC Weather warned of rain between 9 am and 10 am on 30 September 2026 following overnight temperatures above 20 °C across the capital
BBC Weather experts anticipate a significant chance of rain throughout the weekend. Sunday, August 30, which includes the family and children's day and parade, is predicted to be wet for most of the day. The outlook for Bank Holiday Monday, August 31, the main adult parade day, is also concerning, with overnight rain expected to be followed by regular showers from approximately 2pm until 9pm. Thunder is forecast to begin around 7pm on Monday.
Jim Dale, from the British Weather Services, has also predicted a likelihood of showers during the carnival period. While he forecasts temperatures could reach up to 24°C, describing the conditions as 'pleasant' rather than hot, he cautioned that attendees should 'look over our shoulders' for rain. Mr. Dale attributes the unsettled weather to an area of low pressure moving in from the west.
