Recent forecasts from multiple sources project Guangzhou's overnight low on September 20 around 25–27°C amid persistent subtropical heat, with daytime highs near 34–36°C and scattered thunderstorms possible. This setup favors moderate radiative cooling under partial cloud cover rather than extreme drops or retained warmth, explaining the tight 50% market-implied odds on ≤21°C versus ≥31°C. Thunderstorm timing, humidity levels near 60–70%, and light southerly winds represent key variables that could shift the minimum by several degrees, while historical September 20 lows average 23.8°C. Updated model runs from regional meteorological agencies will likely refine these thresholds ahead of resolution.

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.
