Recent forecast guidance from the Korea Meteorological Administration and supporting models highlights a peak daytime high near 29–31°C for Busan on August 18, shaped by the North Pacific High maintaining warm, humid maritime air while afternoon sea breezes along the southern coast provide measurable cooling. Scattered cloud cover and isolated showers or thundershowers introduce variability that limits extreme heating, aligning with historical late-August climatology of 29–31°C maxima. These factors concentrate trader-implied probabilities on the 29°C and 30°C outcomes, with shorter-term updates on convective timing and marine layer depth likely to refine resolution based on official daily maximum observations.

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 18 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.
