Recent meteorological observations and ensemble forecasts from the China Meteorological Administration and global models indicate Shanghai's overnight minimum on June 15 will reach 22°C, driven by stable subtropical high-pressure influence, moderate easterly flow, and typical East Asian monsoon transition patterns that suppress stronger cooling. Mid-June climatology shows average lows of 21–23°C, with current surface observations and short-range guidance aligning tightly around this value. Trader consensus at 100% reflects this narrow uncertainty range and proximity to resolution. An unanticipated cold surge or localized heavy precipitation could still shift the recorded minimum by 1–2°C at official stations.
