Recent forecast runs indicate persistent thunderstorm activity and variable cloud cover over Guangzhou on September 23, creating genuine uncertainty in peak daytime heating and driving the tight clustering of market-implied odds around 33–35°C. Official guidance from sources like WeatherBug and WindBorne shows highs near 31–32°C under partly cloudy skies with 60% storm chances, while historical September averages sit at approximately 31°C; however, brief clearing between convective cells or stronger insolation could allow temperatures to reach the upper 30s. Traders appear to weigh model spread in steering patterns and moisture profiles, with resolution hinging on the exact timing of any rain suppression. Updated numerical weather prediction outputs over the next 48 hours will likely refine these probabilities ahead of market close.

The resolution source for this market will be information from NOAA, specifically the highest 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.
