Recent meteorological forecasts from models aligned with the China Meteorological Administration and global ensembles indicate a minimum temperature of 21°C in Shanghai on October 13, driven by persistent cloud cover limiting nighttime radiative cooling and moderate northerly winds. This consensus underpins the market's strong 95% implied probability for 21°C, reflecting traders' assessment of stable conditions typical for mid-October in the Yangtze River Delta. Minor downward revisions remain possible if clearer skies develop overnight or if observational data from urban stations records greater cooling than projected, though current model agreement leaves limited scope for outcomes below 20°C.
