Recent Met Office guidance for London points to a minimum nighttime temperature of 18°C on August 17, establishing the central driver behind the closely matched 39.5% and 31.5% market-implied odds for 18°C and 19°C outcomes. Ensemble forecasts show limited spread in overnight radiative cooling under mostly clear to partly cloudy conditions, with light easterly winds and dew-point values supporting minima clustered near 17–19°C. Historical August climatology for central London records typical overnight lows of 14–16°C, so the current mild pattern reflects above-average temperatures persisting into mid-month. Traders appear to weigh small differences in model resolution of boundary-layer mixing and urban heat-island effects against the official 18°C baseline, with updated guidance expected from the Met Office and ECMWF runs overnight.
