Recent numerical weather prediction models and climatological baselines position 25°C as the leading outcome for Shanghai’s lowest temperature on July 5, reflecting typical early-July subtropical monsoon conditions where nocturnal radiative cooling is limited by high humidity and prevailing southerly flow. Ensemble guidance shows overnight lows clustered near 24–26°C, with limited spread due to stable large-scale patterns and no strong frontal passages or tropical influences expected in the 48-hour window. Trader consensus aligns with this central tendency, as 25°C commands over half the probability while adjacent bins capture residual forecast uncertainty. Updated runs from global and regional models will refine these values ahead of market resolution.
