**Forecast models for Guangzhou on September 3, 2026, point to overnight lows primarily in the 23–25°C range, shaped by increased cloud cover, scattered showers, and northwesterly flow associated with an early-September frontal system.** This setup favors radiative cooling under overcast skies while limiting daytime heating, keeping the daily minimum near or slightly below the 1991–2020 climatological average of 25°C. Historical records show the date’s all-time low at 22.7°C (2022), so cooler outcomes remain plausible if rainfall is heavier or winds strengthen. Multiple short-range guidance suites (including GFS/ECMWF analogs) currently cluster around 24–25°C minima, with some runs dipping toward 22–23°C amid 40–80% precipitation probabilities. Warmer scenarios (26°C+) would require clearer skies or a delayed system, while sub-22°C readings would need stronger northerly advection or prolonged rain-cooled air. Updated model runs and official guidance from regional meteorological centers in the next 24–48 hours will likely refine these ranges and influence market-implied probabilities, particularly around the 24–25°C cluster currently favored by traders.

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.
