Highest temperature in Jeddah on June 29?

Prediction market odds reflect aggregated trader beliefs and often diverge from traditional meteorological forecasts. While weather analysts rely on physics-based models and historical data, this market incorporates real-time information, trader conviction, and financial incentives to be accurate. Comparing the implied temperature range from market odds to official forecasts from agencies like the Saudi National Center of Meteorology can reveal where traders see gaps or disagreement in the data. Such divergences sometimes signal emerging consensus about extreme heat or cooler-than-expected conditions.
