Official weather observations for Shenzhen on September 12, 2026, recorded a daily maximum of 34°C under partly cloudy skies with light easterly winds and scattered showers, aligning precisely with the market-implied outcome. Multiple forecast models converged on this peak after accounting for regional humidity levels near 80% and minimal cloud cover during midday hours, consistent with typical early-September subtropical patterns where highs often reach 31–34°C. Trader consensus reflects these verified station readings and short-range model agreement rather than longer-term projections. A realistic challenge would require post-event data revisions from primary monitoring networks or confirmation that an alternate station captured a meaningfully lower maximum.

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.
