Recent forecasts from sources like timeanddate and AccuWeather indicate Shanghai's overnight low on August 17 will likely settle near 24–25°C amid typical late-summer conditions, with high humidity, cloud cover, and scattered showers moderating radiative cooling. These factors, combined with the urban heat island effect and steering patterns from the subtropical high, position 25–26°C as the market leaders at 72% combined implied probability. Model consensus shows limited variability, though revisions in the final 48-hour runs from agencies such as the China Meteorological Administration could shift outcomes if a clearer night develops.
