**Consistent numerical weather prediction models from sources including GFS and local meteorological agencies point to a minimum temperature near 22°C in Shanghai on September 21, 2026, driving the 77% market-implied probability for that outcome.** Overnight radiative cooling under partly cloudy skies and light northerly winds is expected to produce a diurnal range of roughly 7–8°C from daytime highs near 29–30°C. Recent observations and short-range guidance show stable conditions with no significant frontal passages or moisture surges altering the thermal profile in the past 24–48 hours. Historical September baselines for the region average lows around 20–22°C, aligning with the current consensus and limiting upside or downside surprises in the final hours before resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
