**Recent forecasts from multiple meteorological sources indicate a nighttime low in Shanghai of 22–24°C on September 20, 2026, under clear to partly cloudy skies with light northeast winds of 5–10 km/h and moderate humidity (60–80%).** These conditions favor moderate radiational cooling overnight after daytime highs near 29–30°C, consistent with late-September subtropical patterns in the region. Trader consensus, reflected in the 60% implied probability for 24°C and 30% for 25°C, aligns with model consensus from GFS and local agencies showing stable high pressure and no significant frontal activity or precipitation to alter temperatures. Historical September lows average near 20–22°C, but current observations and short-term model runs support slightly warmer readings due to urban heat retention and weak onshore flow. Updated hourly data through evening will refine the exact minimum recorded at official stations, with resolution hinging on the final overnight reading before dawn.

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.
