This market will resolve to the temperature range that contains the highest temperature recorded at the Incheon Intl Airport Station in degrees Celsius on 17 Apr '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 Incheon Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/kr/incheon/RKSI. 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.Korea Meteorological Administration's latest aviation forecast projects a maximum temperature of 17°C in the Seoul area on April 17 under cloudy conditions, following recent warmer highs of 19–23°C on April 15–16 amid a high-pressure ridge. This aligns with trader consensus implying 54% odds for 18°C or higher, balanced against 19.5% for exactly 17°C, reflecting spring forecast uncertainty where models like ECMWF and GFS often diverge 48 hours out due to frontal passages and variable cloud cover. Mid-April climatology averages 16–18°C highs, with recent erratic patterns—fluctuating hot-cold swings—driving bets on upside potential from clearer breaks. Watch KMA short-term updates tomorrow for refined guidance ahead of resolution.
