Recent forecasts from multiple models, including those aligned with China Meteorological Administration guidance, point to a maximum temperature in Shanghai on August 26 of 31–33 °C under partly cloudy skies, light easterly winds, and typical late-summer humidity levels near 65–75 %. This consensus drives the near-even market split between 31 °C and 32 °C, with lower odds on 33 °C reflecting modest model spread in peak afternoon heating. Stable regional pressure patterns and the absence of strong frontal systems or monsoon surges limit variability, while historical August baselines for the area average 31 °C highs. Updated short-range runs expected in the next 24–48 hours will further narrow resolution criteria tied to official station readings.
