**Forecast models from the China Meteorological Administration and local Shenzhen stations indicate overnight lows near 25–26°C under partly cloudy conditions with light easterly winds and high humidity (65–90%).** These factors limit radiative cooling after sunset, keeping minimum temperatures above typical early-autumn baselines while preventing sharper drops that would favor outcomes at or below 21°C. Scattered showers or thicker cloud cover could modestly suppress the low, while clearer intervals might allow brief cooling toward 24–25°C. Trader sentiment reflects this narrow range, with near-even implied probabilities around the 25–26°C thresholds underscoring uncertainty in exact nocturnal boundary-layer conditions and any late-day precipitation timing before 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.
