Forecast consensus from the Korea Meteorological Administration and supporting models points to a 34°C daytime maximum in Busan on August 21, driven by typical late-summer conditions under the North Pacific High that sustain warm, humid air with limited cloud cover or precipitation. This aligns with August climatology where daily highs often reach 30–32°C but can peak higher during stable anticyclonic patterns, as confirmed by recent observational trends and ensemble runs. The market-implied odds reflect traders' assessment of these verified forecast outputs over historical baselines. A stronger-than-expected afternoon shower or shift in steering winds could cap readings below the threshold, while clearer skies or delayed cooling might push localized measurements higher.

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 21 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.
