Recent official and model forecasts for Shanghai point to an overnight low near 27–28°C on August 24, consistent with the market’s heavy weighting on those outcomes. Mid-August climatology shows typical minimums of 26–28°C under prevailing subtropical high pressure and high humidity, with limited diurnal cooling. Recent daily markets, including the August 20 resolution at 27°C, reinforce trader reliance on stable summer patterns absent typhoon or frontal passages. Model consensus from sources such as timeanddate and AccuWeather currently favors 81°F (27°C) lows, though small revisions in guidance could shift probabilities between the two leading contracts before official station data finalize the result.
