**Recent official and model forecasts for Shanghai on August 28, 2026, center on a daytime high near 31–32°C under mostly cloudy skies with showers or thunderstorms.** Multiple sources, including Chinese meteorological services and international models, consistently project highs in the 30–33°C range, with rain probabilities of 40–90% and accumulations of 1–5 mm. Easterly to southeasterly flow and increased cloud cover are expected to suppress peak heating compared to clearer days earlier in the week. Shanghai’s late-August subtropical climate features average highs near 31°C; the current setup reflects typical monsoon influences with moisture limiting insolation. This explains the market’s strong weighting toward 31°C (53.5%) and 32°C (23.5%), while lower odds on 30°C or 33°C+ reflect forecast uncertainty in exact timing and intensity of precipitation. Updated model runs over the next 24–48 hours, particularly from the National Meteorological Center or global ensembles, will provide the clearest near-term refinements ahead of 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.
