Traders see the lowest temperature in Shenzhen on September 13 split closely between 24°C and 26°C because official forecasts and model guidance converge on overnight lows in that narrow range under persistent subtropical moisture. High humidity near 80-95% and widespread cloud cover limit nocturnal radiative cooling by trapping longwave radiation, while light easterly winds reduce turbulent mixing that could otherwise allow sharper drops. Scattered showers and thunderstorms further moderate temperatures by enhancing downward heat flux. Differentiation between the leading outcomes hinges on precise timing of any partial clearing or wind shifts before dawn, as even modest changes in these variables can shift the minimum by 1-2°C in Shenzhen’s urban environment. Updated model runs and local observations through the night remain the key near-term drivers.

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.
