**Trader consensus strongly favors a 22°C low for Shanghai on June 16, driven by consistent official forecasts from the China Meteorological Administration and international models showing overnight minima stabilizing near that level amid typical mid-June plum rain conditions.** High pressure and moderate easterly flow have maintained temperatures above seasonal averages without significant cooling influences, aligning with historical mid-month lows averaging 21–22°C at Pudong International Airport. Recent model runs show minimal spread, reinforcing the narrow probability band. A realistic challenge would require an unforecasted cold surge or measurement anomaly at the reference station, though current observations and ensemble agreement make such shifts improbable before resolution.
