Recent forecast model runs from the Met Office and ECMWF indicate potential for enhanced radiative cooling under clearer skies and lighter winds over southeast England, supporting the market's leading 46.5% implied probability for a London minimum of 13°C or below on August 1. With outcomes clustered tightly between 13–19°C, traders are weighing subtle differences in cloud cover, dew point, and urban heat island effects that can shift overnight lows by 2–3°C. Historical August minima average near 15°C, but current guidance shows modest high pressure influence that may suppress temperatures without strong cold advection. New model updates and observations through July 31 will likely refine these probabilities ahead of resolution.
