Recent Met Office guidance and ensemble forecasts indicate overnight lows near 17–18 °C for London on 25 August under high pressure, with clear skies and light winds favoring radiational cooling after daytime maxima around 25 °C. Trader consensus clustering on 16–17 °C reflects modest model spread in boundary-layer mixing and dew-point depression, alongside historical late-August climatology where minima average 14–15 °C but have trended warmer in recent years. Key variables remain the precise timing of any Atlantic front and urban heat-island effects, with updated runs from the Met Office and ECMWF expected before market resolution to refine these thresholds.
