Forecast models and observational data from agencies like the China Meteorological Administration support a minimum temperature near 22°C in Shanghai on June 15, driven by persistent cloud cover and high humidity during the East Asian Meiyu season. These conditions suppress nighttime radiative cooling, maintaining overnight lows in the typical 21–23°C range for mid-June rather than allowing sharper drops. Recent extended forecasts consistently project lows around 71–73°F (22–23°C) amid light rain or overcast skies, aligning with historical climatology where average June minima hover near 20–22°C. Strong trader consensus on 22°C reflects this narrow scientific outlook, though a sudden clearing of skies or an unforecasted frontal passage could permit additional cooling toward 20°C or below.
