Official Korea Meteorological Administration forecasts for Busan on August 20, 2026, indicate a daytime maximum of 32–33°C under mostly cloudy skies with light westerly flow and low precipitation chances, driving the market's near-certain positioning on 33°C. This aligns with regional summer climatology where August highs often reach the low 30s amid humid conditions, supported by current observational data showing temperatures climbing toward that threshold. Model consensus from agencies like KMA reinforces this outcome, with traders weighting official guidance heavily due to real-time verification of the daily high. A shift in steering patterns or unexpected cloud cover could cap readings below 33°C, while clearer skies or stronger warm advection might push the peak higher, though such revisions appear unlikely given the latest model runs.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Gimhae Intl Airport Station in degrees Celsius on 20 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Gimhae Intl Airport Station, available here: https://www.wunderground.com/history/daily/kr/busan/RKPK.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
