Highest temperature in Los Angeles on July 12?

Prediction market odds often diverge from traditional weather forecasts because they incorporate real-time trader sentiment and incentivize accuracy through financial stakes.

Traders may price in factors like historical volatility, recent weather patterns, or model disagreement that analysts emphasize differently. Comparing the market's implied probability to official forecasts can reveal where the crowd sees upside or downside risk relative to expert consensus.
