Recent forecasts from sources including the China Meteorological Administration and international models point to a minimum temperature near 24°C on September 10 in Guangzhou, driven by northerly winds advecting slightly cooler air and overnight cloud cover with scattered showers that limit radiative cooling. This aligns with the market-implied 24°C outcome at 23% while supporting elevated odds on 19°C or below (39.5%) amid model spread and historical precedent of rare dips to 19.4°C. Average September 10 lows hover around 24.6°C, but current steering patterns and 65–70% storm probabilities introduce downside uncertainty that traders are weighting heavily ahead of final observational 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=zggg
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.
