Ensemble forecasts from GFS and ECMWF models drive the tight trader consensus for Jeddah's highest temperature on April 16 at King Abdulaziz International Airport, projecting peaks of 33–36°C amid persistent high pressure and hazy skies following early April's unusual cold wave and thunderstorms. These implied probabilities—clustered around 30–31.5% for 33–36°C—reflect climatological mid-April highs near 34–35°C, with minor divergences arising from uncertainties in Red Sea sea breeze timing, which moderates coastal peaks, and variable low-level humidity affecting afternoon heating. Recent National Center of Meteorology updates confirm sunny conditions ahead, but new 12-hourly model runs could shift the balance before resolution.
