Recent forecast updates for Busan highlight strengthening northeasterly winds and mostly clear to partly cloudy skies on September 7, promoting greater overnight radiative cooling and supporting the market's emphasis on cooler minimums near or below 20°C. Official guidance from Korean meteorological sources projects daytime highs of 26–29°C with overnight lows around 21–23°C, though model runs show divergence on exact clearing and wind strength that could push the daily minimum lower. Historical early-September averages for Busan lows near 22°C provide context, while the absence of significant precipitation or tropical systems reduces warming influences. Traders appear to weigh these factors against remaining forecast uncertainty ahead of final observational data.

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.
