Current ensemble forecasts from global and regional models indicate a September 22 minimum in Qingdao near 19–21 °C, driven by clear skies under a subtropical ridge and light southerly flow that limits nocturnal radiative cooling. Recent surface analyses show no strong cold-air advection or frontal passage expected in the next 48 hours, keeping temperatures above seasonal norms for mid-autumn. Trader sentiment remains split because small shifts in wind direction, cloud cover timing, or boundary-layer moisture could alter the overnight low by 2–4 °C, pushing outcomes toward either the cooler cluster (14–18 °C) or the warmer bin (23 °C+). Updated model runs and local observational data through September 21 will likely tighten the range before 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=zsqd
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.
