Recent global forecast models, including GFS runs, point to a minimum temperature in Jeddah near 29–30°C on October 8, driven by persistent high humidity near 70–80% overnight, light northwest winds, and mostly clear skies that limit radiative cooling along the Red Sea coast. These conditions align with typical early-autumn climatology for the region, where urban heat retention and warm sea-surface temperatures often hold nighttime lows above 28°C. The tight clustering of market-implied odds around 30°C versus 25°C or below reflects model consensus tempered by uncertainty in exact wind shifts or minor cloud increases that could permit a brief dip toward 27°C. Updated high-resolution model outputs and local observations expected early on October 8 will likely resolve the narrow spread between these outcomes.
