Forecast models from sources including ECMWF runs and regional observations indicate a September 26 minimum temperature in Jeddah near 28–30°C, driven by typical late-summer conditions: clear skies overnight, northwest winds of 3–7 m/s moderating radiative cooling, and elevated dew points near 23–25°C from Red Sea moisture that limits temperature drops. Recent days showed stable high pressure with no significant synoptic systems, though a brief dip to 26.7°C on September 23 highlights potential for short-term variability tied to wind shifts or humidity changes. Trader consensus clusters around 30°C while assigning notable probability to 26°C or below and 36°C+, reflecting model spread in nocturnal boundary-layer processes and the narrow resolution thresholds for daily minimums in this humid coastal environment. Updated forecasts and local station data will clarify the exact outcome before resolution.
