Korea Meteorological Administration (KMA) short- and medium-range forecasts project Busan's highest temperature on April 13 at 21–22°C, driving the 94.5% market-implied probability for 20°C or higher amid a high-pressure ridge promoting subsidence, clear skies, and southerly flows that enhance spring solar heating. Current observations on April 11 show daytime highs near 20°C with light winds and low humidity, aligning with model ensembles like those from ECMWF and GFS analogs integrated by KMA, which indicate minimal cloud interference or cold air advection through mid-week. This positioning reflects trader consensus on climatological norms—early April averages of 17–18°C—now exceeded by persistent warming trends. Realistic challenges include an unanticipated northerly wind shift or thickening marine stratus, potentially capping peaks at 19°C, though ensemble spreads suggest low risk; monitor KMA updates issued twice daily for refinements ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Gimhae Intl Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
