Recent short-term forecasts from agencies like the China Meteorological Administration and international models (GFS, ECMWF) indicate Shanghai's September 4 minimum will likely settle near 25–27 °C under persistent cloud cover, light northeast winds of 5–10 m/s, and modest moisture from lingering monsoon influences. Current observations show overnight lows around 25 °C amid scattered showers, with daytime highs near 29–31 °C preventing strong radiative cooling. These conditions align with early-September climatology for the Yangtze River delta, where urban heat-island effects and high humidity typically limit diurnal ranges to 4–6 °C. Trader consensus reflected in the 50.5 % and 37 % implied probabilities for 27 °C and 26 °C captures this narrow window, with lower outcomes discounted absent a stronger cold-air intrusion. Final resolution will hinge on official Shanghai Observatory readings overnight September 4–5.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
