**Forecast models indicate an overnight low near 22°C for Busan on September 14, driven by a stable warm air mass, light variable winds, and high regional sea-surface temperatures that limit radiative cooling.** Partly cloudy skies and moderate humidity further moderate temperature drops, consistent with late-summer climatology where Busan lows typically range 20–23°C. Multiple sources, including global and regional models, converge on this range with low precipitation risk, supporting market-implied probabilities clustered around 20–22°C while assigning meaningful weight to warmer outcomes if the marine layer or wind patterns shift. Traders weigh these factors against normal early-autumn variability and any late model updates.

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=rkpk
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.
