This market tracks whether Seoul's daily maximum temperature will be exactly 17°C on April 19, 2026. Late April falls within Seoul's spring season, when daily highs typically range from 15°C to 22°C depending on weather patterns and atmospheric conditions. The current 1% odds reflect the specificity of this prediction—hitting an exact temperature is inherently unlikely, as weather varies in decimal increments throughout the day. Traders are pricing this as a near-zero probability event, suggesting Seoul is expected to trend cooler or warmer based on seasonal forecasts. The market will resolve using official data from Korea Meteorological Administration, which records the daily high at Seoul's primary weather station. As April 19 approaches, odds may shift if weather forecasts indicate conditions moving toward or away from 17°C. This recurring weather market appeals to traders expressing granular temperature views, with the specificity making it a niche vehicle for weather enthusiasts and climate-focused traders.
