Highest temperature in Shanghai on July 11?

Platform comparison

Market context

Shanghai Pudong International Airport will record its peak daily temperature on 11 July 2026, with the market resolving to the Celsius range containing that high. July is historically the hottest month at this station, averaging a high of 31°C and frequently exceeding 35°C during sunny spells [1][5]. The current 0% YES probability implies the crowd expects the temperature to fall outside the specific range offered, yet comparable years show highs regularly reaching 32–35°C in mid-July, making a zero-probability stance unusual unless the range is set extremely low [2][5].

Programmatic traders should monitor real-time Wunderground feeds for the station ZSPD, automating conditional orders when hourly readings breach the upper bound of the target range. Key catalysts include the daily 14:00 local maximum temperature updates and any sudden shifts in cloud cover or precipitation, as gusty winds and rain forecast for Saturday 11 July could suppress peak temperatures [2][7]. A script querying the hourly table from Yr or Weather.com can detect deviations from the 30–32°C norm, triggering copy-trading bots to adjust positions before the 12:00Z settlement window closes [9][10].
