Recent forecast consensus from meteorological agencies points to a daily maximum of 32°C in Shanghai on August 27 under partly cloudy skies with scattered showers and moderate northeast winds of 15–25 km/h. These conditions, typical of late-summer subtropical monsoon patterns, limit strong daytime heating while preventing significant cooling from heavy rainfall. Observed temperatures through midday have hovered near 31–33°C, keeping 32°C as the market favorite at 67% implied probability. Nearby historical analogs and model runs show only modest variance, supporting the lower probabilities assigned to 31°C and 33°C. Updated afternoon observations and any intensification of showers could still shift the final high before resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
