Recent short-range forecast models from agencies including the China Meteorological Administration indicate Shanghai highs near 29–30°C on August 15 amid increasing cloud cover, scattered thunderstorms, and moderating onshore flow typical of late-summer East Asian monsoon patterns. These conditions align with climatological cooling from peak July values, where daily maxima average 31–32°C but frequently drop 1–3°C under rain-cooled air masses. Elevated humidity and potential precipitation reduce surface heating, supporting the market’s emphasis on the 29°C outcome while leaving room for 30°C if clearer skies develop. Updated model runs in the next 24–48 hours will refine timing of any convective activity and final maximum readings.
