Recent forecasts from the Shanghai Meteorological Bureau and international models indicate overnight lows of 27–28°C on August 28 under persistent cloud cover, easterly winds, and light rain, with high humidity limiting radiative cooling. This aligns with recent daily minima of 26–27°C amid typical late-summer monsoon conditions. Trader emphasis on these outcomes reflects model consensus on minimal day-to-night temperature swings, while lower probabilities for 26°C or below account for slight forecast uncertainty in precipitation timing. Official resolution will rely on verified station readings from the China Meteorological Administration.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=zspd
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
