Recent forecast consensus from multiple models points to a maximum temperature in Shanghai on August 30 of 31–32°C as the most probable outcome, with showers and southeast winds limiting daytime heating. Persistent cloud cover, high humidity near 80–90%, and precipitation chances above 60% suppress peak readings below recent clear-sky values near 33°C, while variable steering patterns and model spread create tight differentiation between the two leading bins. Official updates from agencies like the China Meteorological Administration over the next 12–24 hours will refine the exact high before 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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the 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.
