Recent forecasts from Chinese meteorological services show Shanghai under easterly flow with persistent cloud cover, light rain, and high humidity on August 28, producing an expected overnight low of 27°C. Multiple observational and model runs align on this minimum, consistent with late-summer subtropical monsoon patterns where typical lows range 26–28°C amid weak diurnal temperature swings of 3–5°C. Official station data through the period reflect this stability, with dew points near 25°C limiting further cooling. A rapid shift in steering winds or unexpected clear-sky radiational cooling could push readings lower, though current consensus across agencies makes such divergence unlikely before resolution.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 28 Aug '26.
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.Recent forecasts from Chinese meteorological services show Shanghai under easterly flow with persistent cloud cover, light rain, and high humidity on August 28, producing an expected overnight low of 27°C.
