Current forecast consensus from multiple meteorological sources indicates Shanghai's overnight low on September 13 will likely reach 22–24°C under clear skies and light northeast winds of 2–5 m/s. A stable high-pressure ridge near 1018–1019 hPa supports modest radiative cooling after sunset, while dew points around 19–20°C and urban heat retention limit further drops. Model runs show minimal disagreement, with no incoming fronts or precipitation expected overnight. This positions 23°C as the modal outcome in trader sentiment, consistent with historical September climatology where minimums average near 20–22°C but recent dry, settled conditions have kept readings slightly higher. Updated guidance through the evening of September 12 will refine these probabilities.

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.
