Trader consensus strongly favors 27°C as Shanghai’s lowest temperature on September 3 due to real-time observations and model consensus showing an overnight minimum settling near that level. Persistent light rain, high humidity near 80-90%, and northeasterly winds have moderated radiative cooling under overcast skies, preventing sharper drops typical of clearer conditions. This aligns with early-September climatology for the region, where daily minima often range 24-28°C amid monsoon influences. A sudden clearing of clouds could allow additional cooling to 26°C or below before official station readings finalize, while continued precipitation and cloud cover would reinforce the current positioning. Market resolution depends on the final verified minimum from authoritative meteorological data.

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.
