Recent numerical weather prediction ensembles from sources including the Korea Meteorological Administration and global models indicate afternoon highs in Busan on September 13 clustering near 28–29°C under stable high pressure, with light southerly winds and partly cloudy skies. This setup supports the market’s tight clustering of implied probabilities around 30–31°C, as modest variations in insolation from cloud timing and boundary-layer mixing can shift the daily maximum by 1–2°C. Historical September baselines for the region average near 27°C, but current dry conditions and weak sea-breeze development raise the potential for brief spikes above 30°C before any evening cooling. Updated model runs and local observations over the next 48 hours will refine these thresholds ahead of market resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Gimhae Intl Airport Station in degrees Celsius on 13 Sep '26.
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.Recent numerical weather prediction ensembles from sources including the Korea Meteorological Administration and global models indicate afternoon highs in Busan on September 13 clustering near 28–29°C under stable high pressure, with light southerly winds and partly cloudy skies.
