Recent short-term forecasts from agencies like the Shanghai Meteorological Observatory and international models indicate nighttime lows of 25–27°C on August 25, aligning with trader consensus favoring 27°C (54.5% implied probability) and 26°C (25%). Shanghai’s subtropical monsoon climate, moderated by the East China Sea and urban heat retention, typically produces August minimums near historical baselines of 25–26°C absent strong frontal systems or typhoon influences. Current model runs show stable high pressure with light southeasterly winds and limited cloud cover, reducing cooling potential overnight. No major weather shifts have emerged in the past 48 hours to alter this range, though final official minimum readings from local stations will determine resolution amid normal forecast uncertainty of 1–2°C.
