Recent forecasts from multiple meteorological sources converge on a daily maximum of 31–32°C for Shenzhen on September 24, aligning with the market’s leading outcomes at 42% and 29.5% implied probability. Late-September subtropical conditions, including moderate easterly flow, partly cloudy skies, and isolated showers, are expected to cap daytime heating near seasonal norms of 31°C while preventing spikes above 33°C. Hourly model runs and current observations showing afternoon peaks near 31°C have reinforced trader consensus, though scattered convection introduces minor uncertainty in the final official reading. Resolution will depend on the highest verified station temperature reported by Chinese meteorological authorities.

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=zgsz
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.
