Recent forecasts for Shanghai indicate a minimum temperature near 26–27°C on August 13, driven by persistent summer monsoon moisture, high humidity near 80%, and expected cloud cover with showers that limit nocturnal radiative cooling. Official guidance from sources such as the Hong Kong Observatory shows overnight lows around 26°C amid overcast conditions, while extended models highlight variability from 23–28°C depending on timing and intensity of precipitation. These factors create tight differentiation between adjacent outcomes, as even modest shifts in cloud persistence or rainfall can alter the low by 1–2°C through changes in heat retention and urban heat island effects. Traders weigh model consensus against climatological August averages of 25–26°C, with fresh forecast updates likely to refine the market-implied odds ahead of resolution.

This market will resolve based on the lowest 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 lowest temperature recorded at the Shanghai Pudong International Airport Station in degrees Celsius on 13 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
