**Northeast winds and clear-to-partly cloudy skies are supporting radiative cooling overnight in Shanghai, positioning the daily low near 22–24 °C.** Official and model guidance from sources including Chinese meteorological services and international forecasts consistently project a minimum between 21–23 °C (roughly 70–73 °F) under light-to-moderate northeasterly flow and dew points in the mid-teens °C, limiting further nocturnal temperature drops. This aligns with climatological September averages for the city, where mid-month lows typically range 21–23 °C. With the market heavily favoring 24 °C (77.5 % implied probability) followed by 23 °C (23 %), traders appear to be weighting the upper end of the forecast envelope, possibly reflecting recent model runs showing slightly warmer boundary-layer conditions or minimal cloud cover reducing heat retention. No major synoptic shifts or precipitation are expected to alter the pattern before dawn, keeping the outcome range narrow and data-driven.

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.
