Highest temperature in Munich on June 18?

Prediction market odds often diverge from traditional meteorologist forecasts because they incorporate real-time trader sentiment and financial incentives alongside official models. While weather agencies publish point estimates and confidence intervals based on atmospheric data, this market aggregates the beliefs of participants who profit or lose based on accuracy. Comparing the implied probabilities here to published forecasts from national weather services can reveal where the crowd expects surprises—such as unusual heat or cooler-than-expected conditions—offering a complementary perspective to institutional predictions.

Major weather model updates, seasonal forecasts, and real-time atmospheric patterns will drive significant price swings in this market. A shift toward a heat wave or an unexpected cold front could rapidly reprrice the odds.
