Official forecasts from Chinese meteorological agencies project a daily low of 26°C in Shanghai on August 18, supported by subtropical high-pressure dominance that limits overnight radiative cooling under humid summer conditions. Model consensus and recent station data align closely with mid-August climatological norms of 25–27°C lows, showing no major frontal systems or typhoon influences to alter the pattern. Trader consensus at 99% for this outcome reflects high confidence in stable atmospheric conditions, with resolution hinging on verified end-of-day minimum readings. Minor deviations could arise from localized showers or increased cloud cover enhancing cooling, though current guidance indicates low likelihood of shifts below 25°C or above 27°C.

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 18 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.
