Recent forecasts from regional models indicate a high near 27°C for Busan on September 16 under partly cloudy skies, northeast winds of 10–18 km/h, and stable high pressure around 1017 hPa, supporting the tight clustering of market-implied odds between 28°C and 29°C. These outcomes hinge on the balance between daytime solar heating over the coastal plain and moderating sea breezes plus variable cloud cover that can suppress peak readings by 1–2°C. With no active typhoon or frontal systems nearby, the main variables remain the precise timing of maximum insolation and any late-day marine layer development, factors that KMA observations and ensemble guidance will clarify in the next 48 hours.

The resolution source for this market will be information from NOAA, specifically the highest 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.
