Recent forecast models from Chinese meteorological services indicate a highest temperature in Shanghai on August 28 most likely between 30–32°C, driven by persistent cloud cover, scattered showers, and easterly winds that limit daytime heating. Multiple sources converge on a 31–32°C maximum under partly cloudy to overcast skies with precipitation probabilities around 40–80%, consistent with late-August climatology for the region. This scientific consensus underpins the market’s leading implied probabilities for 31°C and 32°C, while model variations in rainfall timing and wind strength introduce modest uncertainty that could shift the precise peak by 1°C. Updated observations tomorrow morning will refine the final recorded maximum used for market 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.
