Trader consensus overwhelmingly favors a high of 18°C in Shanghai on March 22, driven by converged forecasts from authoritative models like ECMWF and GFS, alongside local observations from the Shanghai Meteorological Service indicating mild spring conditions with highs stabilizing around 17-19°C amid light southerly winds and partial cloud cover. Historical March data supports this, with median highs near 14°C but recent warming trends pushing averages up slightly; current ensemble predictions show over 95% agreement within 1°C of 18°C. Realistic challenges include an unforeseen warm advection from the south or urban heat island amplification at the Pudong measurement site, though low-pressure systems forecasted to dominate reduce upside risks for 20°C+.
