Official forecasts from the Met Office and BBC Weather project a minimum temperature of 9–11°C for London on June 9, with the lowest readings expected overnight under partly cloudy skies and light westerly winds. This aligns with early-June climatology, where London’s average overnight lows range from 10–12°C. Model consensus shows limited variability, supporting the market’s 98.9% implied probability for exactly 10°C. A shift toward clearer skies or calmer winds could enhance radiative cooling and push the minimum below 10°C, while increased cloud cover or stronger winds would likely keep readings near or above that threshold. No major data releases or model updates are expected before resolution.
