Recent forecast models from sources like the GFS and local observations show Shanghai experiencing clear to partly cloudy skies with light northeast winds, supporting radiative cooling overnight but moderated by urban heat effects and residual warmth from recent days. This has positioned the minimum temperature near 23–24°C, aligning with the market's leading implied probabilities for 24°C and 25°C as traders aggregate real-time model consensus and historical September baselines around 20–22°C. No significant cold air advection or frontal systems have emerged to push values lower, while daytime highs near 29–30°C limit further nocturnal drops. Updated agency briefings and next model runs will refine resolution criteria tied to official station readings.

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.
