Recent forecasts from the China Meteorological Administration and international models show Shanghai under mostly cloudy skies with light easterly winds and minimal precipitation on September 23, supporting a daily high near 28–29°C. This aligns with late-September climatology for the region, where typical highs range 27–30°C absent strong synoptic forcing. Model consensus remains tight with low uncertainty in the short-range window, as no significant frontal systems or tropical moisture intrusions are projected to alter temperatures before resolution. Trader positioning at 50% for 28°C and 39.5% for 29°C reflects this stable outlook, though minor revisions in afternoon convective development could shift the exact peak.

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 23 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 forecasts from the China Meteorological Administration and international models show Shanghai under mostly cloudy skies with light easterly winds and minimal precipitation on September 23, supporting a daily high near 28–29°C.
