This market tracks whether Tokyo's highest temperature on April 20, 2026, will be exactly 20°C—a narrow prediction target that requires precise meteorological conditions. Tokyo's spring temperatures typically range from 15–22°C in mid-April, depending on weather systems moving across the region. The specificity of 20°C makes this scenario relatively uncommon, reflected in the current 4% YES odds. This low probability suggests traders view this outcome as unlikely based on typical April weather patterns in Tokyo. Temperature predictions require precise meteorological data; the market resolves using official readings from Tokyo's meteorological stations on the specified date. Weather at 20°C in April represents mild, temperate conditions common during spring transition periods, but hitting exactly this figure requires favorable atmospheric conditions. Over the next 24 hours, odds may shift as weather forecasts update and as April 20 approaches. Historical April data indicates Tokyo temperatures typically drift across a wider range, from cool mornings to warmer afternoons, making exact matches less frequent. This market appeals to weather enthusiasts and prediction market traders who closely monitor Japan's seasonal temperature patterns and enjoy precision-based weather trading.
