**Forecast models from sources like WeatherBug, LUFT TIME, and Yr.no indicate overnight lows for Guangzhou on September 21 in the mid-20s °C (roughly 25–27°C), driven by persistent cloud cover, high humidity near 70–80%, and scattered thunderstorms expected overnight.** Light southeasterly winds and the subtropical monsoon pattern limit radiative cooling, keeping temperatures above the historical average low of 23.7°C for the date. Model consensus shows minimal spread in minimum readings, with precipitation timing as the main variable that could nudge the exact low by 1–2°C. This supports trader focus on mid-range outcomes while the near-even split between sub-20°C and 30°C+ bets reflects broader uncertainty around convective activity and any late model shifts rather than current observational data or climatology.

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.
