Recent Met Office and supporting model guidance indicate that clear to partly cloudy skies combined with light southwesterly winds will allow London’s overnight minimum to settle at 17°C, consistent with the 100% market-implied outcome. Surface observations through the evening show temperatures already tracking this level under stable high pressure, with dew points and radiative cooling rates aligning with climatological expectations for mid-June. The consensus reflects verified station data rather than projections. A late surge in cloud cover or an unexpected wind shift could raise the minimum by 1–2°C, while clearer skies and lighter winds than modeled might allow a brief dip below 17°C before resolution.
