Forecasts for Shanghai on August 15 point to a peak near 29–30°C under overcast skies and scattered thunderstorms, keeping the market tightly split between those two bins. Subtropical monsoon moisture and variable cloud cover are limiting daytime heating compared with clearer summer days, while steering patterns keep the area under a moist, stable air mass. Official guidance from extended models shows only modest day-to-day shifts, so traders weigh the latest runs against historical mid-August maxima around 31°C. Resolution hinges on the single highest official reading, making small differences in timing of rain or breaks in cloud cover decisive for whether the peak reaches 30°C or stays at 29°C.
