Forecast ensembles from the ECMWF and GFS models show tight convergence on an overnight low of 19°C for Shanghai on May 17, directly supporting the market’s 99.4% implied probability for that outcome. Mid-May climatology under neutral spring conditions typically produces Shanghai minima between 17°C and 21°C, shaped by East Asian monsoon maritime air and variable cloud cover that limits radiative cooling. A persistent high-pressure ridge could nudge readings slightly higher, while a passing weak trough or enhanced sea-breeze advection might trim the low by one degree. Traders monitor the next China Meteorological Administration and ECMWF runs for shifts in boundary-layer moisture or wind patterns ahead of final resolution.
