Trader sentiment favors a Shanghai high of 16°C at 24.5%, closely trailed by 14°C and 17°C, reflecting ensemble forecast models like ECMWF and GFS clustering in the mid-teens amid mild early-spring conditions. Recent model runs show a tight spread due to a weakening cold front from the north, with southerly winds and partial cloud cover tempering extremes; historical March 22 averages hover at 13-15°C, but urban heat island effects boost readings by 1-2°C. Differentiation hinges on uncertainty in boundary layer mixing and sea breeze onset—favoring 16°C if clearer skies prevail, versus cooler 14°C under lingering overcast—per China Meteorological Administration updates, keeping lower and higher tails subdued.
