Recent Korea Meteorological Administration guidance favors a daytime maximum of 28–30 °C in Busan on May 18, driven by a strengthening high-pressure ridge and southerly flow that advects warmer maritime air while promoting subsidence and reduced cloud cover. These synoptic conditions align with the market’s tight clustering around 29 °C and 30 °C outcomes, reflecting modest uncertainty in sea-breeze onset and afternoon mixing that can cap or slightly elevate the peak reading. Mid-May climatology for coastal Busan typically centers near 20–22 °C, so the current setup represents an above-average anomaly tied to the ridge’s persistence. Traders are monitoring the next KMA update and any shifts in boundary-layer moisture or timing of onshore winds, which could nudge the observed high into the adjacent bins before resolution.

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 May '26.
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.Recent Korea Meteorological Administration guidance favors a daytime maximum of 28–30 °C in Busan on May 18, driven by a strengthening high-pressure ridge and southerly flow that advects warmer maritime air while promoting subsidence and reduced cloud cover.
