**Official surface observations across Shanghai stations recorded a daily maximum temperature of 29°C on September 21, 2026, under partly cloudy skies with light northeasterly flow and minimal precipitation.** Multiple forecast models converged on this value days in advance, reflecting stable synoptic conditions typical for late September in the Yangtze River Delta, where diurnal warming peaks near 29–30°C absent strong frontal systems or enhanced insolation. Trader consensus at 100% implied probability for the 29°C outcome aligns with these verified measurements rather than projections, as real-time data from sources like the China Meteorological Administration confirm the exact threshold. Minor station-to-station variations or post-event quality-control revisions remain the primary realistic scenarios that could shift resolution, though current consensus across independent datasets strongly supports the observed 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=zspd
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.
