Recent forecast guidance from global models shows Shanghai highs near 30–32°C on June 11 amid the early plum-rain season, with variable cloud cover and scattered showers moderating daytime peaks while high humidity sustains warmth. Ensemble spreads reflect uncertainty in steering flows and timing of any convective activity, keeping 29–31°C outcomes dominant in trader pricing. Historical June averages hover around 27–28°C, but recent years have seen frequent 30°C+ readings before the full monsoon onset. Updated model runs over the next 48 hours, particularly from regional high-resolution systems, will likely tighten the distribution ahead of the daily maximum observation used for resolution.
