Latest official forecasts from regional models place Jeddah’s daytime maximum near the late-May climatological average of 36°C under persistent high pressure, clear to hazy skies, and moderate northwest winds off the Red Sea that limit further warming. These conditions align with historical May baselines where strong solar heating is modestly offset by coastal moderation, producing negligible precipitation risk and keeping peaks from exceeding the mid-30s. Trader consensus at 36°C reflects this model agreement and the narrow historical range for the date. Shifts in steering winds, unexpected afternoon cloud cover, or stronger interior heat advection could still trim or add a degree before the official station reading is finalized.
