Short-term forecast uncertainty amid persistent monsoon moisture and storm activity drives the closely matched Polymarket odds clustered around 26–28°C for Guangzhou’s August 27 nighttime low. In the city’s humid subtropical regime, dew points near 26–28°C and widespread cloud cover from regional flows limit radiative cooling, while variable wind and precipitation timing can shift minima by 1–2°C. Historical late-August averages near 25°C and recent model consensus around 25–27°C support the narrow range, with lower probabilities for extremes reflecting reduced likelihood of clear skies or strong advection. Updated CMA and global model runs over the next 48 hours will refine these thresholds 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=zggg
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
