Recent forecasts from multiple models place Shanghai's August 5 peak near 34°C amid persistent subtropical high pressure and high humidity, with scattered thunderstorms and variable cloud cover introducing uncertainty in the exact daily maximum. Recent days have featured highs of 35–37°C under mostly sunny conditions, but increasing easterly flow and moisture could cap temperatures or allow brief cooling spikes depending on storm timing and intensity. Official guidance highlights typical August variability around the 32–35°C range, where small shifts in insolation or precipitation timing differentiate outcomes near the market's closely bunched 32–35°C probabilities. Updated model runs and afternoon observations will refine the resolution criteria before the date.
