**Recent forecasts from multiple meteorological sources, including Chinese weather services and international models, indicate Shanghai's overnight low on August 29 will most likely settle near 27–28°C.** This aligns with the market's heavy weighting toward 27°C (57%) and 28°C (31.5%), reflecting aggregated trader assessment of model consensus under persistent late-summer conditions. Shanghai's subtropical monsoon climate in late August features high humidity, southeast winds, and frequent light rain or drizzle that limit radiational cooling overnight. Current data show dew points near 26°C, cloud cover, and scattered precipitation holding minimum temperatures elevated compared to clearer nights. Official outlooks list ranges such as 27–32°C or 28°C lows, consistent with historical late-August baselines around 24–27°C but tempered by the ongoing moist air mass. No strong cold front or significant model divergence appears in the short-term guidance, keeping probabilities concentrated on the narrow 26–28°C band. Updated runs from agencies like the China Meteorological Administration and global ensembles will refine exact thresholds ahead of resolution, with any clearing skies or heavier rain potentially shifting the minimum by 1–2°C.
