Highest temperature in Panama City on June 28?

Prediction market odds often diverge from traditional meteorological forecasts because traders incorporate real-time data, historical patterns, and risk sentiment into their pricing. While weather analysts publish point estimates and confidence intervals based on atmospheric models, this market aggregates dispersed trader knowledge into a single probability. Comparing the two reveals whether the crowd is more bullish or bearish on extreme heat than official forecasts suggest, offering a complementary lens on outcome likelihood.
