Ensemble forecasts from GFS (NOAA) and ECMWF models, updated in the last 24 hours, project Jeddah's highest temperature at King Abdulaziz International Airport on April 15 around 34–36°C under persistent subtropical high pressure promoting subsidence and clear skies for strong daytime heating. This drives the tight market-implied odds clustering at 33–36°C, with 34°C leading at 32.5% trader consensus. Differentiating factors include model spread on sea breeze timing from the Red Sea—which could moderate peaks via onshore flow and marine layer development—and potential afternoon cumulus clouds; earlier onset favors 33°C, delays push toward 36°C+. Historical April highs average 33°C amid rising seasonal trends, but inherent short-range uncertainty persists ahead of final 12z runs and observations.
