Forecast models from multiple sources project a daytime maximum of 32–33 °C in Shanghai on August 29 under partly cloudy conditions with light showers possible and southeast winds near 10–20 km/h. This aligns with late-August climatology, where average highs reach 31 °C amid high humidity and monsoon influences that can suppress or enhance afternoon peaks depending on cloud cover and timing of any convection. Recent observations show 30–32 °C highs the prior two days with scattered rain, supporting the market’s strong preference for 32 °C (61 % implied probability) while leaving room for 31 °C or 33 °C if steering patterns or insolation shift slightly. New model runs and official briefings tomorrow will refine the exact peak 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.
