Seoul experiences variable spring weather in April, with daily high temperatures typically ranging from 12°C to 22°C depending on weather patterns. On April 18, 2026, traders are predicting whether the city's highest temperature will reach exactly 16°C. This market resolves based on official temperature data from Seoul's meteorological stations. Currently trading at 1% YES odds, the market signals strong conviction that the peak temperature on April 18 will not be exactly 16°C—traders assess that conditions will either be cooler or warmer than this specific threshold. The low odds likely reflect the difficulty of predicting a precise temperature rather than a range. Historical April weather in Seoul shows highly variable conditions depending on weather systems moving through East Asia. The market will settle once the daily high temperature is officially recorded, making this a binary outcome tied directly to verifiable weather data. Early trading volume of $5,848 in the past 24 hours reflects active interest in Seoul's daily temperature markets among weather prediction traders.
