**Current forecasts from multiple meteorological sources indicate a minimum temperature for Guangzhou on September 21 likely falling in the mid-20s °C, aligning with the closely matched market-implied probabilities around 24–26 °C.** High humidity levels near 80–95% overnight, combined with partly cloudy skies and a chance of showers or thunderstorms, are expected to limit radiative cooling and keep the low from dropping sharply below recent norms. Model outputs, including detailed hourly runs, show early-morning readings stabilizing near 24–27 °C after daytime highs of 32–35 °C, consistent with late-summer subtropical conditions where weak steering winds and persistent moisture moderate temperature swings. Traders appear focused on the narrow band of outcomes because small shifts in cloud cover timing or localized precipitation could easily move the exact minimum across the 24–26 °C thresholds, while lower probabilities on 23 °C or below reflect the limited cooling potential under these conditions. Updated model runs and overnight observations ahead of the 24-hour resolution window will be the key variables.

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 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.
