Recent meteorological observations and forecast models from agencies monitoring East Asian weather patterns show Shanghai's daily maximum temperature stabilizing near 30°C on September 5, supported by partly cloudy skies, light northeasterly winds, and moderate humidity levels around 60-70%. This aligns with climatological norms for early September in the region, where subtropical high pressure typically moderates extremes. Trader consensus at near-certain implied probability reflects the tight clustering of official readings and ensemble predictions around this threshold. Realistic challenges include localized convective activity or station-specific microclimate variations that could nudge the recorded high by 1°C, though current atmospheric stability makes larger shifts unlikely before resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Shanghai Pudong International Airport Station in degrees Celsius on 5 Sep '26.
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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Recent meteorological observations and forecast models from agencies monitoring East Asian weather patterns show Shanghai's daily maximum temperature stabilizing near 30°C on September 5, supported by partly cloudy skies, light northeasterly winds, and moderate humidity levels around 60-70%.
