**Shanghai's typical July overnight lows hover near 26–28°C amid high humidity and limited radiative cooling.** With the plum rainy season recently concluded, clearer skies and reduced daytime cloud cover can allow modest nighttime temperature drops, while elevated moisture levels and urban heat island effects often keep minimums from falling much below 27°C. Forecast models for July 26, 2026, show consensus around these values, with subtle differences driven by expected wind patterns, any lingering shower activity, and the precise timing of peak cooling after sunset. Elevated typhoon risk this month introduces potential for increased cloud cover or rain, which would suppress radiative losses and favor the higher end of the 27–29°C range. Trader sentiment clusters tightly because ensemble guidance remains closely aligned on these thresholds, with minor model spreads determining whether the low settles at 27°C, 28°C, or 29°C. Official China Meteorological Administration updates and short-range model runs over the next 48 hours will refine these probabilities.
