Recent forecast consensus from regional models and the China Meteorological Administration indicates a daily maximum near 32°C for Guangzhou on September 16, driven by persistent subtropical warmth, light southerly flow, and moderate humidity levels around 65-75%. Scattered thunderstorms and variable cloud cover introduce the main uncertainty, as earlier or more widespread precipitation could cap temperatures at 31°C while delayed or lighter activity allows brief peaks toward 33-34°C. Historical September averages near 32°C and low wind shear support the current distribution, with traders weighting the most recent model runs showing limited intensification potential before any frontal passage. Updated guidance expected overnight will clarify resolution risks around the 31-33°C thresholds.

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.
