Recent forecasts from multiple models indicate Shanghai's overnight minimum on September 22 will likely fall in the 22–24°C range, with 23°C and 24°C emerging as the closest market outcomes due to subtle differences in predicted cloud cover and wind patterns. Stable high pressure and light northeast flows are limiting radiative cooling, while partly cloudy conditions and moderate humidity (around 70–80%) moderate temperature drops. Historical late-September baselines average near 22°C, but current steering patterns favor slightly milder nights. Traders are weighing the next CMA and ECMWF model runs, which could resolve the narrow spread before resolution.

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.
