Korea Meteorological Administration's latest short-term forecast projects Seoul's high temperature at 24°C on April 15 amid an early heatwave, with minimums around 12°C, partly cloudy skies transitioning to clear, and low precipitation risk of 20% in the morning. Trader consensus on Polymarket, however, clusters tightly around 18–20°C (implied probabilities 21–27%), reflecting adjustments for resolution at Incheon International Airport station—typically 3–5°C cooler than central Seoul due to coastal marine influences and less urban heat island effect. Recent volatility, including a resolved cold snap and April 13 highs reaching 25–28°C regionally, underscores model ensemble spread in upper-air patterns and cloud cover variability, with historical mid-April averages near 18°C providing baseline context. New KMA updates due within 24 hours may refine exact peak.
