**Trader sentiment for Shenzhen’s September 18 overnight low reflects substantial forecast uncertainty, with market-implied odds nearly even between 31°C or higher (38.0%) and 21°C or below (37.5%).** In Shenzhen’s subtropical monsoon climate, September lows typically average 24–26°C as the summer monsoon weakens and easterly flows strengthen, but short-term variability arises from cloud cover, humidity, and wind patterns that control nocturnal radiative cooling. Clear, drier conditions under high pressure can drop temperatures several degrees below seasonal norms through enhanced longwave radiation loss, while persistent moisture, light winds, or approaching weather systems limit cooling and keep readings closer to daytime levels. Recent model guidance shows modest cooling around 25–26°C, yet divergence in ensemble runs highlights sensitivity to small shifts in steering patterns or moisture. Updated forecasts from regional meteorological centers over the next 48 hours will likely resolve much of this spread 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.
