Current ensemble guidance from the European Centre for Medium-Range Weather Forecasts and NOAA’s Global Forecast System shows tight convergence on an overnight minimum near 19 °C for Shanghai on May 17, establishing this outcome as the dominant driver of trader sentiment. Mid-May climatology places typical lows between 17 °C and 21 °C under neutral springtime conditions modulated by the East Asian monsoon’s maritime air and variable cloud cover. A weak trough or enhanced sea-breeze advection could nudge readings toward 18 °C, while a persistent high-pressure ridge favors 20 °C. With resolution hours away, traders are monitoring the final China Meteorological Administration and ECMWF model updates for any boundary-layer moisture or wind shifts that could alter the narrow 18–20 °C spread.
