Current forecasts from global and regional models place Guangzhou's September 20 maximum in the 33–36 °C range, with ensemble spreads and afternoon thunderstorm potential creating the tightest probabilities around 34–36 °C. High humidity, light winds, and partial cloud cover typical of late-summer subtropical conditions limit extreme heating, while any break in cloudiness or delayed convection could push readings toward the upper end of that band. Historical September 20 highs average 31.6 °C with a 36.1 °C record from 2024, providing context for the market's clustering. Updated CMA guidance and the next GFS/ECMWF runs will refine steering patterns and instability indices ahead of official station observations used for resolution.

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.
