Recent forecasts from sources including the BBC, AccuWeather, and local Chinese weather services indicate Shanghai's overnight low on August 23 will most likely fall between 26–28°C amid typical late-summer conditions of high humidity, light easterly winds, and scattered showers or drizzle. These align with climatological baselines for the period, when average minimums hover near 26–27°C and daytime maxima reach 31–33°C. No strong cold-air intrusion or typhoon influence appears in current model guidance, keeping probabilities concentrated on 27°C (market-implied 50%) and 28°C (35.5%), while the modest 12.5% chance for 26°C reflects residual uncertainty in evening cloud cover and precipitation timing that could modestly suppress the low. Updated model runs from the National Meteorological Center and regional ensembles over the next 24–48 hours will provide the key data shift for traders.
