Recent forecasts from sources including the Shenzhen Meteorological Bureau and international models indicate a daily maximum near 31°C under partly cloudy skies with light showers possible, driven by typical late-September subtropical moisture and easterly flow without strong warming or cooling influences. This positions 31°C and 32°C as leading outcomes in trader consensus, reflecting observed temperatures hovering in the upper 20s°C midday and historical September averages around 31°C. Minor model variations in cloud cover and precipitation timing introduce uncertainty for 30°C or 33°C scenarios, with final resolution dependent on official station readings as the day concludes.

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