Current forecast models from the European Centre for Medium-Range Weather Forecasts and Global Forecast System point to an overnight low near 20–22°C in Shanghai on May 20, driven by southerly flows, elevated dew points near 19°C, and persistent cloud cover that limits nocturnal radiative cooling. These conditions contrast with historical May averages of 16–18°C and recent cooler minima earlier in the month, yet the absence of northerly intrusions or clear-sky episodes keeps sub-18°C outcomes less favored while still leaving room for modest variability. Urban heat island effects around Shanghai Pudong International Airport further anchor readings above 19°C, with traders weighting the 20–22°C cluster most heavily amid thin liquidity and expected model updates in the next 48 hours.
