Recent Met Office and ensemble forecast models indicate the daily minimum temperature in London on October 13 will settle near 14°C, driven by mild southwesterly flow, persistent cloud cover, and limited radiative cooling overnight. This produces the near-certain 99.5% market-implied probability for a 14°C low, consistent with current observations showing temperatures holding in the low-to-mid teens through the night. Historical October averages near 9°C provide context for the milder anomaly, though model consensus remains tight. A sudden clearing of skies or northerly wind shift could enhance surface cooling and push readings lower, but current atmospheric conditions make significant deviation unlikely before resolution.
