Highest temperature in Madrid on July 13?

Prediction market odds often diverge from traditional meteorological forecasts because they incorporate real-time trader sentiment and broader information flows. While weather analysts rely on numerical models and historical data, this market aggregates the collective judgment of participants betting on the actual outcome. Traders may price in uncertainty, recent weather patterns, or climate anomalies that official forecasts weight differently. Comparing the market's implied probability to published analyst predictions can reveal where consensus is strongest or where contrarian views are gaining traction.
