Trader consensus on Polymarket reflects tight forecast uncertainty for Seoul's highest temperature on March 27, with models implying a narrow range around 13–15°C as the most probable outcomes. Korea Meteorological Administration (KMA) and global ensembles like ECMWF and GFS show consensus highs of 12–16°C, driven by lingering cold continental air masses from Siberia clashing with early spring warming under weak high-pressure ridging. Recent 72-hour model runs indicate slight divergence: ECMWF leans marginally warmer at 14–15°C due to enhanced southerly flow, while GFS favors 13°C amid potential cloud cover from an approaching low-pressure system. Historical March 27 averages hover at 12°C, but positive temperature anomalies from El Niño decay add upside risk. Daily KMA updates through March 26 will refine land surface conditions and boundary layer stability, potentially tipping the balance.

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.
