Seoul experiences significant temperature variation throughout April, with highs typically ranging from 12 to 18 degrees Celsius during the spring season. April 20 falls in the latter part of spring, when the city transitions toward warmer weather patterns. This market specifically tracks whether Seoul's highest temperature on that date will be exactly 14°C—a precise daily temperature prediction common in weather markets. The current YES odds of 23% suggest traders assign roughly a one-in-four probability to this exact outcome occurring. Resolution depends on official meteorological data from Seoul's primary weather station, making this market directly tied to verifiable real-world conditions. The specificity of predicting an exact daily high adds significant complexity; weather systems rarely produce precisely calibrated temperatures. Recent volatility in Seoul's April temperatures has kept these precision markets moderately active, with participation concentrated around realistic seasonal ranges. Traders assess both historical April temperature patterns and current weather forecasts to evaluate the likelihood of hitting this specific threshold. The market's $1,771 daily volume and $3,493 liquidity demonstrate moderate engagement in daily temperature prediction markets.
