Korea Meteorological Administration's (KMA) latest short-term forecast projects Seoul's May 16 morning low—measured 3-9 AM KST at the official station—near 15°C amid partly cloudy conditions and a 20-60% chance of light rain overnight May 15-16, driving tight market-implied odds with 15°C at 27% slightly ahead of 16°C at 24%. This reflects genuine uncertainty in global model ensembles, where GFS runs trend 1°C cooler than ECMWF due to divergent simulations of nocturnal radiative cooling under variable cloud cover and light southerly winds mixing warmer air aloft. A warmer-than-average 2026 spring raises the climatological baseline (historical mid-May lows cluster 12-16°C, median ~14°C), but recent frontal influences introduce cooling potential; watch KMA's 11 AM and 5 PM updates May 15 for shifts ahead of resolution.

The resolution source for this market will be information from Wunderground, specifically the lowest 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.
