Traders see nearly even odds around 25–28°C for Shenzhen’s September 23 minimum because official station observations and model consensus place the overnight low near 26°C under partly cloudy, humid conditions with light easterly winds. Subtropical monsoon patterns keep sea-surface temperatures elevated, limiting nocturnal cooling, while scattered showers and high dew points near 24°C further moderate the drop. Hourly data show temperatures falling from evening peaks near 30°C only to the mid-26°C range by early morning, with minimal model spread across guidance. Resolution hinges on the precise 24-hour minimum recorded at the primary meteorological station, where small variations in cloud cover or wind could shift the final value across the tightly contested thresholds.

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.
