**Recent model consensus from regional forecasts points to overnight minima near 24–26°C for Shenzhen on September 12, driven by persistent subtropical moisture, light northeast winds, and scattered convective activity that limits strong radiational cooling.** High humidity (often 80–90%) and cloud cover from potential thunderstorms reduce the diurnal temperature range, keeping lows above historical early-September averages around 24°C. Trader emphasis on the 21°C-or-below outcome (49.5% implied probability) likely reflects uncertainty in forecast spread—possible clearer skies or a weak frontal passage could enhance cooling—while the 31°C+ bucket (23.5%) captures upside risk if convection suppresses overnight. Upcoming CMA and global model runs will refine these thresholds ahead of 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=zgsz
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.
