Trader consensus centers on a 30–32°C daily high for Shanghai on August 22, 2026, with 31°C carrying the highest implied probability. This reflects model agreement on typical late-summer subtropical monsoon conditions featuring persistent cloud cover, high humidity near 80–90%, and scattered thundershowers that moderate surface heating through reduced insolation and evaporative cooling. Official extended guidance from sources such as timeanddate and BBC shows highs near 31–32°C (89–90°F) under overcast or broken skies, consistent with seasonal baselines where convection often caps peaks before they reach 34°C or higher. Recent forecast updates have reinforced this range rather than shifting toward clearer, hotter scenarios, leaving lower-probability tails for extremes driven by unexpected clearing or stronger subsidence.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 22 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Shanghai Pudong International Airport Station, available here: https://www.wunderground.com/history/daily/cn/shanghai/ZSPD.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
