Highest temperature in Buenos Aires on June 15?

Prediction market odds often diverge from traditional weather analyst forecasts because they incorporate real-time trader sentiment and financial incentives alongside meteorological models. While professional forecasters rely on physics-based climate simulations and historical data, this market aggregates the beliefs of many participants with money at stake, sometimes surfacing consensus faster or highlighting uncertainty that models alone may not capture. Comparing the implied probabilities here to published forecasts from regional meteorological services can reveal where market participants expect conditions to differ from baseline predictions.
