**Recent short-range forecasts from sources like timeanddate and regional models show Shanghai's overnight low on August 18 centering in the mid-20s°C amid typical late-summer conditions of high humidity, scattered thundershowers, and variable cloud cover.** These factors limit nocturnal radiative cooling, keeping minimum temperatures from dropping sharply while preventing extreme warmth. Ensemble guidance clusters around 26–27°C as the most probable range, with minor spreads arising from differences in predicted rainfall timing, wind speeds, and urban heat retention. Historical August baselines for the city hover near 25–26°C lows, and the tight market split between 26°C and 27°C reflects this narrow uncertainty band ahead of final observational data from official stations. Updated model runs over the next 24–48 hours will likely refine the exact minimum before 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 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.
