This market predicts whether Milan's highest temperature on April 20, 2026 will be exactly 19°C. Milan in late April typically experiences mild spring weather, with average highs in the 18–22°C range, making a precise 19°C outcome plausible but dependent on specific atmospheric conditions and synoptic patterns that day. Spring in northern Italy is characterized by variable weather as cold air masses interact with warming Mediterranean air, creating conditions where day-to-day temperatures can shift significantly. The market's 3% YES odds suggest traders expect temperatures to deviate substantially from this exact point—either warmer, which is more likely given seasonal trends and current climate patterns, or cooler. The market resolves against official meteorological data from Milan's primary weather station, ensuring accurate and unambiguous settlement. Current odds reflect the inherent difficulty of predicting exact temperature points rather than broader ranges, combined with the uncertainty in short-term weather forecasting. Daily temperature precision markets demonstrate how weather prediction becomes exponentially less probable as specificity increases.
