Seoul experiences significant temperature variation in mid-April as spring transitions toward warmer weather. The weather prediction market for April 18 trades the possibility of the daily high reaching exactly 14°C. At 0% odds, traders currently assess this outcome as extremely unlikely, suggesting market consensus that Seoul's peak temperature on that date will either exceed or fall below this specific threshold. Historical April data for Seoul shows daily highs typically ranging from 12°C to 20°C, though specific precision at single-degree resolution is inherently uncertain. Weather prediction markets rely on official meteorological data from Korea's Meteorological Administration to determine whether the highest recorded temperature matches the exact threshold. The lack of trading activity at 0% odds reflects the narrow probability band—most traders view it more probable that Seoul will experience warmer conditions fitting the broader spring warming pattern. Volume of $3,780 over 24 hours indicates modest but consistent interest in daily temperature markets for the Seoul region.
