**Forecast models from sources including the Hong Kong Observatory and local Guangdong meteorological reports indicate the lowest temperature in Shenzhen on September 20 will likely fall between 26°C and 27°C.** This range aligns with the leading market-implied probabilities, driven by the ongoing northeast monsoon maintaining easterly flow, moderate humidity near 80%, and limited overnight radiative cooling under partly cloudy skies with isolated showers possible. Typical September climatology for the region shows average lows near 24°C, so current conditions reflect slightly warmer-than-normal persistence without significant cold-air advection or clear-sky cooling. Thunderstorm activity later in the day is not expected to substantially depress minimums, supporting trader focus on these narrow bands ahead of final observational data.

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.
