Madrid experiences variable spring weather in April, with daily highs typically ranging from 15°C to 20°C during this season, though occasional warm spells can push temperatures higher. This market resolves on April 20 at midnight UTC based on the official highest temperature recorded in Madrid on that specific date, as measured by local meteorological authorities. A market price of 0% YES odds suggests traders overwhelmingly expect Madrid's peak temperature to fall outside the exact 22°C mark on April 20. Historical weather data shows such precise temperature targets in spring are relatively rare—April highs must exceed current seasonal averages by 2–3°C for this condition to resolve to YES. The market reflects broader meteorological patterns: Madrid's April temperatures fluctuate significantly day-to-day based on pressure systems, Atlantic weather patterns, and seasonal warming cycles, making exact-degree predictions inherently uncertain and volatile. Current liquidity of $9,464 with modest 24-hour volume ($1,248) indicates moderate trading interest in this niche weather market. Traders can adjust positions continuously as new forecast updates refine temperature projections closer to April 20, allowing for dynamic risk management.
