**Strong model consensus and official forecasts from Chinese meteorological services underpin the near-certain 22°C low for Shanghai on September 21, 2026.** Multiple runs project overnight temperatures bottoming near 22°C under partly to mostly cloudy skies, light northerly winds, and moderate humidity around 70-85%, consistent with late-summer climatology for the region. Current observations and short-range guidance show minimal deviation risk, with highs near 28-29°C earlier in the day providing little overnight cooling momentum. Traders assign only marginal probability to 21°C or lower, reflecting typical forecast error margins of 1°C or station-specific measurement differences. An unexpected surge in cloud cover or a sharper wind shift could still nudge readings slightly, though such shifts appear unlikely 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.
